Not only the maneuverability of the car, but also your safety depends on the serviceability of the steering. In some situations, losing control of a car moving at speed can lead to irreparable consequences. If you detect the slightest changes in the behavior of the car or extraneous sounds emanating from the elements of the control system, you should immediately stop driving and take measures to identify and eliminate malfunctions. In this article we will talk about the reasons why a knock occurs in the steering rack when turning the steering wheel, and the possible consequences of this phenomenon using the example of a VAZ-2109 car. We will also try to figure out how to diagnose a malfunction of the rack and pinion mechanism and fix it ourselves.
Types of control systems
The steering design of modern cars can be of two types:
Almost all models of classic VAZs are equipped with the first. It is called a worm because the main element of the mechanism here is the so-called worm, which is a kind of continuation of the steering shaft. It is in constant engagement with a roller mounted on the shaft of the bipod, which, in fact, transmits force to the steering rods. This design allows the wheels to be turned at a large angle and perfectly dampens shock and vibration coming from the wheels.
Front-wheel drive VAZs of the Samara and Lada families are equipped with rack and pinion steering mechanisms. Their mechanism has a different design. Everything is a little simpler here. The end of the steering shaft is equipped with a gear, which, pressing against a special rack that has teeth on the upper side, forces it to move in a horizontal direction. This design is simple, compact and highly reliable.
Disassembly, general progress of work
Before starting repairs, be sure to check that you have a special repair kit on hand. There are two configuration options: full and incomplete. An incomplete set does not include a gear and rack, which will only require a major overhaul of the VAZ 2109 steering rack. A big advantage of the chosen car model is the relatively low cost of component materials, which means that repairing the VAZ 2109 steering rack with your own hands is not only a useful activity in terms of gaining experience , but also quite economical.
So, the painstaking work of disassembling and reassembling began.
More details about the rack and pinion mechanism
At first glance, the design of the rack and pinion mechanism may seem quite complicated. If we take into account only its main parts, not counting the steering wheel and column, then there will be more than twenty of them. The rack itself looks like it has been ground down to half the shaft.
On its upper part there are longitudinal teeth that engage with the drive gear. The rack is enclosed in an aluminum housing filled with a special lubricant. Its central part has holes for attaching the inner tie rod ends. In this place the crankcase has a cut, covered with a rubber boot. Inside, the rail is held in a certain position thanks to a support sleeve, usually made of fluoroplastic. To adjust its mobility, a special stop is used.
As you can see, in fact, there is nothing complicated about the rack and pinion mechanism. If you understand what all the elements are for and how they work, you can service and repair it yourself without any problems.
Assembly removal process
You will not be able to diagnose unless you dismantle the mechanism. This is quite labor-intensive work associated with disassembling several units at once. There are several methods of dismantling, here is one of them:
- Secure the vehicle so that the front is higher than the rear. Place shoes under the wheels to prevent them from moving. Remove the front wheels.
- To ensure you have full access to the steering rack, disconnect the wires and gas canister. Set these details aside.
- Align the wheels with the steering wheel and unscrew the spline bolt near the pedals. To do this, you will need a spanner or universal joint head.
- Clean the tie rod nuts from dirt, then start twisting them with pliers, and then remove them completely with a spanner.
- Use a puller to remove the rods.
- Unscrew the rods from the steering rack housing. You can remove them together with the crankcase, and finally disassemble them in a vice.
- Pull the rack out through the wheel arch. Clean it from dirt and clamp it in a vice for subsequent repairs.
Knock in the steering rack
On average, the stock steering rack of VAZ cars lasts up to 100 thousand kilometers. Naturally, in normal operation. In some cases, it may fail much earlier. The main symptom of a faulty steering rack is a knocking sound. It appears either when the steering wheel is turned sharply, or when it is turned too much, or when it hits a bump. Knocking in the rack can occur due to:
- loosening the thrust nut;
- loosening the tie rod bolts;
- natural wear of the rack or drive gear;
- malfunction of the support sleeve;
- wear of mechanism parts caused by rupture of the boot.
Next, we will look at each of the reasons in more detail, but first we will figure out how to correctly and accurately diagnose a breakdown.
Advantages and disadvantages of DIY assembly
At first glance, there is nothing complicated in such work:
You can save money by purchasing only a repair kit and lubricant, the cost of which is quite reasonable. And at the service you will have to pay for the services of the master. And if the contractor is not entirely honest, then the parts may not be completely new, which will quickly necessitate a second repair. But there are also disadvantages that can affect the operation of the machine immediately or after a short operating period. To avoid mistakes in operation, you should carefully watch the video on how to properly repair the steering rack.
If you notice signs of a faulty steering rack, this does not always mean that a complete replacement of this unit is necessary. In some cases, repairs are sufficient. Stores sell special kits for this. Let's figure out in what cases it is necessary to repair the VAZ-2109 steering rack.
Fault diagnosis
So, if you notice that the steering rack is knocking, you need to determine where exactly this knock is coming from and discard the possibility of malfunctioning elements of the car’s chassis. Let's start with general points. Place the car on a level surface. Leave the cabin, open the hood. Start turning the steering wheel left and right, turning it all the way. If during this process the steering rack knocks, making a characteristic sound when turning the steering wheel sharply, you can be sure that it is definitely it, and not the shock absorbers or CV joints. To be more convincing, ask an assistant to turn the control wheel, and you yourself place your palm on top of its housing. When the wheels turn, you will definitely feel the vibration with your hand during this very knock. These signs are typical for wear of the rack itself, the drive gear, or a malfunction of the support sleeve. Similar symptoms can also appear when the stop nut is loosely tightened.
If the knocking noise does not appear when turning the wheels, pull the steering rods by holding them with your hands. If there is a problem, you will definitely find a corresponding play.
Signs of breakdown
By means of steering racks, rotational movements from the steering wheel through a rack and pinion mechanism are transmitted to the rotary levers, which turn the front wheels with rods.
If you find one of the symptoms listed below on your car, be sure to conduct a full diagnosis of the condition of the unit, and then repair it.
Signs of a faulty steering rack include:
- A grinding noise is observed in the rack area when the steering wheel is rotated;
- The steering wheel periodically sticks;
- Lubricant begins to leak from the seals;
- The steering wheel has noticeable play.
These symptoms may also indicate problems in other components of the steering mechanism, but first you must check the condition of the rack, disassemble it and decide whether to replace or repair it.
Node diagram
Loosening the thrust nut
Often the steering rack knocks due to the loosening of the stop nut, which serves to adjust its movement inside the crankcase. The more it is tightened, the tighter the steering wheel will rotate, and vice versa. In other words, a nut that is loosened more than expected causes play to occur between the rack and the stop. This is what causes the knocking.
It is not difficult to check that the steering rack is knocking precisely for this reason, but for this you will need a special octagonal wrench for 17. You can buy it at any car store. Now you need to find the location of the nut. And it is located on the lower part of the rack housing in the area of the vacuum brake booster. It is usually protected by a plastic or rubber cap that will need to be removed. When this is done, try using a wrench to tighten the nut by turning it counterclockwise. A normal tightening is considered when the nut is screwed in all the way and then loosened by 24 degrees. This ensures a gap between it and the stop equal to 12 mm.
Screw puller
This is a more complex device. To make it you will have to use a welding machine. This device itself works by tightening a nut in a cylinder cut off on one side. Thus, the finger is squeezed out of the socket with minimal effort. You can do something like this:
- We find a suitable cylinder; it should be made of metal 2-4 millimeters thick. On one side, you need to cut a strip along the entire length of the cylinder, its thickness should be no more than 3 centimeters;
- Next, a circle of suitable diameter is cut out of a good iron plate. A notch is cut in it. It should coincide with the empty strip of the cylinder. After which, the workpiece is welded to one of the ends of the cylinder;
- We take a fairly thick plate of iron. Preferably at least 5 millimeters. And also cut out a circle from it. A hole (10) is drilled in its middle. It will need to be threaded. We weld the resulting part to the free end of the cylinder;
- All you have to do is screw a suitable bolt into the hole, and the device is ready for use.
We disassemble the rack
Now we move on to faults that cannot be detected without dismantling the steering mechanism. If you have eliminated the play between the rods and the rack, as well as between it and the stop, but the knocking does not disappear, then you will have to dismantle the entire device.
Repairing VAZ steering racks is not a complicated process. Once you take it apart yourself, you will immediately understand the principle of its operation. First, remove the rubber support located on the right side of the crankcase and remove the rubber boot. On the left side you also need to remove the protective cap and support. Using an octagonal wrench, unscrew the stop nut and knock out the stop.
Using a screwdriver, pry up the rubber boot of the drive gear and remove it. Unscrew the bearing fixing nut with a 24mm wrench. Remove the gear from the crankcase. After this, you can pull out the rail itself.
Eliminating backlash
Of course, major repairs are not necessary in every case, and replacement of component parts is also not always necessary, because:
- On the VAZ 2109, the steering rack is adjustable, and if you know how to tighten the steering rack mechanism, then you can remove steering knocks without any financial investment at all
- This is possible, of course, if the knocking is caused by operational or factory control play
- To adjust, you should use a trestle or inspection hole, find the adjusting nut under a layer of dirt, then use a special wrench “17” to tighten it
We disassemble the rack
When you have eliminated the play, but the knocking has not disappeared, then the steering rack on the VAZ 2109 must be disassembled and repaired:
- Repairing the rack yourself will not be difficult, of course, if you know in what sequence the operations need to be performed
- First, we remove the steering rack, and if everything is in order with the rods, then it is not necessary to remove them, just unscrew them from the unit and that’s it
- Then we clamp it in a vice or in a special device for repair.
- And then remove the clamps securing the protective cap, boot, right support and spacer ring
- Subsequently, all other parts are removed (photo with diagram below), including complete pressing out of the bearings
- Then the parts should be cleaned of dirt as thoroughly as possible, followed by washing them in kerosene
- And after cleaning all the parts, they should be very carefully inspected for signs of tears or other damage.
- If small scuffs can be easily removed with sandpaper, all heavily worn parts, and especially damaged ones, must be replaced
- The same approach applies to bearing troubleshooting.
- In their particular case, if there is the slightest doubt about the performance of these devices, parts should be replaced immediately
- You should also understand that tightening the steering rack itself, the procedure, in principle, is not a difficult operation to perform with your own hands
- But disassembling the steering wheel, and even more so replacing it, may require special skills from you; in addition, you will need competent instructions
- When you have absolutely no time or desire to carry out such operations yourself, or you do not want to delve into all the intricacies of this process, then the best option for you would be to perform all repair work in a specialized automobile workshop
- You, of course, understand that the price of specialist services will cost more than self-repair
- Moreover, the amount of the invoice that you will receive may vary greatly.
- For example, carrying out troubleshooting is one cost, but a complete repair is a completely different one.
Schematic structure of the steering rack, it clearly shows what is removed and then put back on
- It is worth noting that the steering rack is not the cheapest component of a car, so few people dare to replace the whole thing right away.
- Everyone starts by trying to repair the existing device.
- It happens that it is enough to simply adjust it so that the malfunction disappears, or perform a partial repair by replacing the bearings
- Of course, the diagnostic procedure, as well as subsequent repairs, is impossible without disassembling
- Only by disassembling the steering rack will you get a complete picture of the condition of its parts, which parts require improvement (grinding, for example), and which should definitely be replaced
- Repair in almost any case will be much cheaper than a complete replacement
- And if you repair the rack yourself, you will also save on the cost of auto mechanic services
- To carry out independent repairs, as has been mentioned more than once, you will need a repair kit, specific keys, as well as a set of bearings and grease.
- Not a lot of money is spent on purchasing components
- However, if you have replaced all the bearings, as well as seals and lubrication, and still have problems with the operation of the machine, then you will still need the services of specialists to determine the exact cause of the failure or replace the “serious” (major) components
- The most remarkable thing is that in the conditions of the modern total “deficit” of finance, a complete replacement of the entire unit is resorted to only in extreme cases, when there is nothing left to repair in the old one
Wear
Pay attention to the condition of the drive gear. Its teeth should not show any signs of mechanical damage.
If they are present, it needs to be changed. The same applies to the rack teeth. Place the gear on it and watch how they engage. If wear is evident, it is better to replace the mechanism. Repairing steering racks, which involves restoring them, is possible, but hardly justified. Even if we manage to do something, it won’t be for long. Over time, the malfunction will definitely manifest itself.
If the mechanism is worn out, there is only one way out - a new steering rack. The price of the assembled spare part is about 3,500 rubles. Agree, it’s not that expensive when it comes to safety.
Post navigation
Many car enthusiasts are mistaken in believing that the steering rack on a VAZ is not adjustable and it is impossible to do it yourself. This is a misconception and adjustment of the steering rack on a VAZ car can be carried out by any car enthusiast independently. We will now explain how to tighten the steering rack on a VAZ-2115.
On the website of the official Moscow VAZ dealer, read the description of the entire model range, pay attention to the Lada Largus - what configuration the car is currently offered, with what engines and in what version. For each Lada Largus model, exact prices are indicated. Choose a new car!
Now let's tighten the steering rack:
Support sleeve
Are the rack and pinions ok? Go ahead. We remove the fluoroplastic bushing from the crankcase. It is because of this that the VAZ-2109 steering rack most often knocks, or rather, because of its wear. If it is worn out or deformed, we replace it immediately, since it costs mere pennies. But it is best to buy not just one, but a repair kit, which also includes a stop with a nut and a spring, as well as a set of seals and gaskets. By replacing the bushing and all these small elements, you will get a completely working steering rack.
Repair kit contents
If the question you are interested in is “which one to choose,” then there will be practically no recommendations here, because the design of all mechanisms in VAZ car models is almost identical. So:
- Just remember that you should beware of counterfeits when purchasing.
- And one more thing you should definitely know before purchasing a steering rack repair kit is the fact that they come in different configurations
- The simplest and, therefore, the cheapest repair kit includes only a washer, nut, and bearing, as well as fluoroplastic bushings, since bushings are consumables
- The average-priced kit is the same kit, only complete with all bearings and shafts
- And finally, the most expensive configuration option, which is used to perform major repairs, is equipped directly with a new steering rack
We have completed a detailed diagnosis of the problems, there will be another article about detailed repairs, so as not to search for it, it’s better to watch the repair video.
Boot rupture and mechanism wear
The rubber boot on the crankcase serves to protect the entire steering mechanism from dirt, dust and moisture. In addition, it prevents lubricant from leaking out of the crankcase. You've probably heard the phrase “steering rack is leaking.” So, this lubricant leaks out through the torn boot. Damage to it will inevitably lead to premature failure of the control mechanism. In addition to leaving it without lubrication, moisture and dust will seriously accelerate the wear process. If you discover that the steering rack is leaking in your car, immediately go to the store for a new boot. And don't forget to buy lubricant.
The cause of knocks from below can be faults not only in the suspension, but also in the steering of the car.
The condition of the steering greatly affects both the ease of driving and traffic safety.
The cause of knocks and vibrations on the steering wheel can be the condition of the ball joints of the steering rods and steering mechanism, and the condition of the car's wheels.
To check the steering, place the car on a horizontal platform, open the hood and perform the following operations.
1. Turn the wheels to the right until they stop. In this position, the left wheel tie rod ball joint becomes accessible, which can be seen from under the left wing of the car.
2. Check the integrity of the rubber protective boot of the steering rod joint.
3. Have an assistant rock the steering wheel from side to side and observe the connection between the ball joint and the telescopic strut arm.
There should be no visible play (play) in the ball joint.
Be sure to replace a tie rod end with a damaged joint boot or increased play in the joint with a new one.
When replacing tie rod ends, wheel alignment angles may be disrupted.
4. Check the condition of the right wheel joint in the same way.
5. A rack and pinion steering mechanism is installed on the front panel separating the engine compartment from the passenger compartment.
Ask an assistant to sharply shake the steering wheel left and right and watch the steering mechanism.
If the steering gear housing moves from side to side, it is necessary to tighten its mounting to the body.
Do not use excessive force when tightening the steering housing nuts as this may cause the studs to break and be difficult to replace.
The tightening torque of the steering gear housing mounting nuts is 15–19 Nm.
6. Pay attention to whether there are any gaps at the junction of the steering rods with the steering rack.
If the gaps cannot be eliminated by tightening the tie rod mounting bolts, then the rubber-metal hinges of the inner tie rod ends must be replaced.
7. Carefully inspect the front tires. Strong impacts from the road surface, especially when hitting potholes, can cause the cords in the tire carcass to delaminate and cause the tire to bulge ("bulge") or become misaligned.
A possible cause of vibration and shock in the steering wheel when driving at speeds above 70–80 km/h may be an imbalance of the front wheels.
Contact a car service center or tire shop to check the balancing of the front wheels.
If shocks and vibrations appear on the steering wheel when you press the brake pedal, contact a car service to replace the brake pads, repair or replace the front brake discs.
Knock on the control rack
Now we will talk about the situation when a knock appeared on the control rack, the prerequisites for this phenomenon and methods for eliminating them.
Adjustment
So, the situation is such that tightening the steering rack can still give a positive result. Therefore, you need to find out how to tighten the knot and what is required for this.
You can adjust the rack through the bottom of the car, removing the engine protection, or through the top. In the second case, the work will have to be done by touch. So decide for yourself what is more convenient for you.
- To adjust the steering rack, you will need to tighten the adjusting screw. You can find it in the steering mechanism. To be more specific, in the end cap.
- It is optimal to have an overpass or a pit at your disposal in the garage. If there are no such conditions, you can get by by raising the car with a jack. Only in this situation will it be necessary to additionally secure the car in order to avoid it sliding off the jack and the likely consequences.
- Before lifting the body with a jack, be sure to align the front wheels straight.
- You can measure the backlash using a backlash meter. Moreover, they can be old or electronic. The latter are more relevant and convenient to use, but some people don’t have to choose. What you find is what you will use.
- According to current norms and standards, for the VAZ 2109 the steering wheel play should not exceed 10 degrees.
- Find the adjusting screw and begin to tighten it gradually. The operation is carried out slowly. Periodically check the steering wheel movement and any play or knocking in the steering column.
- Use a special key for adjustment. It is available at any auto parts store.
- The key is inserted into the adjusting screw and turned counterclockwise. Scroll a little and check the result.
- The procedure may take a long time. Still, take your time.
- When you feel that the adjustment has reached the desired level, take a test drive in your car, feel how the steering wheel moves, whether the knocking or play has disappeared, how hard the steering wheel rotates.
- If the steering wheel has become too tight, you will have to slightly loosen the tension on the adjusting screw.
Rack and pinion control mechanism
A rack and pinion control mechanism is installed in most types of passenger cars.
Rack and pinion control mechanism
It is simpler in design and does not contain enough moving parts, which means it is more reliable.
The main elements of the rack and pinion control mechanism are the gear and the rack.
How does the control mechanism work?
Under impeccable conditions, the entire mechanism will be able to last up to 100 thousand kilometers of the car.
Also, the presence of a rack and pinion control mechanism significantly reduces the price of the car, which is also very important.
But nothing is perfect, and there are problems with the control racks that require both a professional and non-professional approach.
Essential elements
For a VAZ 2109, it is easier to repair the steering rack if you know the operating principle and purpose of each part. The design is very simple, consists of several basic elements:
- a gear rack with two threaded holes for attaching internal rod ends;
- drive gear with a splined shaft for connection to the steering clutch;
- support half rings ensuring smooth sliding;
- a stop mechanism that regulates the required design clearance of the gear pair;
- a crankcase into which the parts are assembled and fixedly attached to the car body;
- sealing elements and protection against dust and dirt.
The repair kit comes in two types: incomplete, which contains rubbing parts, rubber products that require periodic replacement, and disposable clamps. In case of breakage or wear of the teeth and ground surface, you will have to purchase a complete repair kit. It includes absolutely all parts except the crankcase, including a gear pair, needle and ball bearings, and a pressure spring.
Prerequisites for knocking
Knock on the control rack - where does it come from? Let's find the root cause.
Yes, the control rack is a more common system than the outdated worm type.
As previously mentioned above, even in Russian cars it “goes” 80-100 thousand km, without causing any problems for motorists.
But the early knock, as annoying as it may sound, appears from time to time.
The prerequisites are:
- On a VAZ-21099, for example, a knock on the control rack is often caused by insufficiently tightened fastening bolts. No, they were tightened for the sake of it, it was our amazing roads, creating vibrations, that spun them over time. It's not difficult to remove the knocking noise - you just need to tighten all the fasteners.
- On the VAZ-2110 and all cars in the tenth row family, the support bushing on one side of the rack often wears out. Since the support bushings here are made of plastic, their rapid wear does not become a miracle when traveling along our impeccable, so to speak, roads. Convexities contribute to the appearance of free movement of this element, which is why wear occurs at an accelerated pace.
- The situation is much more serious when the covers protecting the control rack are torn. Then dust and dirt have access to its jagged surfaces, which without undue drama looks like a disaster. The rack will not work for a long time without protection, which is why the unfortunate knock occurs.
- Corrosion of a part is generally a fatal problem, since the control rack will have to be completely changed. It is not cheap, but not more expensive than money and, most importantly, life with health.
- Occasionally, but there is a manufacturing defect. Here the rack in most cases knocks already on a brand new car. Fortunately, if the vehicle is considered to be under warranty, then the replacement of a bad component can be achieved through the “establishment” of the manufacturer of the car. Damage at the factory, poor production quality are more common cases of manufacturing defects.
- Lath material. Typically, it is soft and designed for driving on high-quality roads. When driving through our pits and as a result of constant vibration, metal is removed from the surface of the rack evenly layer by layer, micron by micron, and this leads to premature wear of the support sleeve. In this case, the problem can be solved using 2 methods. Either purchase a new rail or order a similar one made from stronger metal. Usually people who do this will advise you on suitable material.
All motorists, without exception, would like to know how to preserve and extend the life of the control rack, because this is not just an expensive, but also an important component, the failure of which often turns into a disaster.
Repair
The first thing you will need to carry out your own repairs is a repair kit. They are available at almost any auto parts store. However, we strongly recommend that you buy only high-quality kits so that the result of your DIY repair lasts as long as possible.
What you need for work
The proposed kits are incomplete and complete. You will definitely need the following kit components:
- Needle bearing;
- A pair of rubber seals for the bushing;
- Support sleeve made of plastic;
- Set of gaskets;
- Spring;
- Retaining rings;
- Support bearing;
- Drive gear;
- Boot cover;
- Rail;
- Set of ties for the boot.
Repair kit Now that the kit is ready, the tools are available, and there is enough free time, you can get to work.
- First, remove the boot, end caps and stops. As you disassemble elements, even the smallest and insignificant at first glance, be sure to evaluate their current condition. If necessary, all worn-out elements will be replaced with new ones taken from the repair kit.
- Using an octagon, unscrew the screw plugs, which will allow you to remove the springs, retaining rings, and thrust bushings.
- Remove the bearing and check if it has any play. The repair kit includes a new bearing, so if the old component is in satisfactory condition, it is better to replace it immediately. It’s not for nothing that you took on such a complex process to get everything done 50%.
- Remove and inspect the drive gear. Next, you can completely remove the rail itself.
- Be sure to replace the support shaft bushing, not forgetting about the rubber bands. They are also included in the kit.
- Take your time to remove the rubber bands from the sleeve. First, insert the element into the crankcase, after which you can cut off the elastic with scissors or a sharp knife.
- The most difficult step is replacing the needle bearing. To remove it, you will need a special key. But you can do without it. In this case, arm yourself with a 1.5 mm drill bit and a drill. Using a drill, make a hole in such a way as to loosen the end of the bearing. Use a punch to knock out the old bearing from the crankcase.
- Before installing the new needle bearing, be sure to thoroughly clean the steering rack housing of accumulated debris and steel shavings from drilling.
- The hole made cannot be left. To eliminate it, you can mix metal filings with superglue. This mixture will harden quickly and give an excellent result.
- Lubricate literally everything that can be lubricated in the steering rack assembly. Experts advise using Litol 24 or other lubricants of similar quality. It wouldn't hurt to lubricate the CV joints.
- Reassemble the unit by following the reverse sequence of dismantling.
If you don’t have a key to remove the needle Repairing the steering rack yourself allows you to significantly save on replacement, plus gain a lot of experience in performing far from the simplest work related to your VAZ 2109. But you can do it easier, without taking any risks, by contacting a trusted car service center. Unit in a vice
Checking status
Having completed the repair, you should not think that now the steering rack will serve tens of thousands of kilometers and will no longer cause you trouble. Like many other components, the condition of the rack must be periodically monitored.
What to look for
Your actions
These fasteners are subject to vibration after repair as they are used. Therefore, it is recommended to check and tighten them every 250-300 kilometers.
You can check it a little less often, approximately every 500-1000 kilometers, depending on the operating conditions of your car. Due to different quality, some anthers can last quite a long time, while others will require replacement after 10 thousand kilometers. The choice is yours which parts to use
The rack itself should be constantly monitored. Listen to the behavior of the steering mechanism, pay attention to the above signs of malfunction. As part of a scheduled technical inspection, be sure to include a check of the steering racks in the list of activities.
The repair cannot be called complicated, but it takes quite a lot of time. Plus, it is extremely important to perform all operations as carefully and efficiently as possible. Otherwise, the result will not last long and you will soon have to interfere with the design of the VAZ 2109 steering unit again
How to extend the life of a control rack
We will give only three pieces of advice:
- Treat your car very carefully, inspect key components more often, and visit diagnostic centers.
- If you find the slightest knock in the rack, immediately go to a car service center, preferably with a tow truck.
- Take a cautious driving style as expected: do not subject the steering to extreme loads, do not operate the steering wheel suddenly without any circumstances.
Do not overload the vehicle with cargo and passengers. Beware of busy driving on rough roads.
So, we have dealt with the common causes of knocking on the control rack and outlined preventive measures.
Read on the topic: Do-it-yourself repair of the VAZ 2110 control rack.
Even with the most careful, delicate driving, it is not possible to keep the car in perfect condition. Our roads, the harsh climate, and the driving style of other road users are all to blame.
If play occurs in the steering unit, it is quite possible to adjust the rack yourself. The process is not complicated, so it is not necessary to contact a service station.
The force on the front wheels of the VAZ 2109 is transmitted through a gear, which, in turn, interacts with a rack. To eliminate any gaps that arise in the engagement, pressure springs are used.
The rack adjustment is carried out in order to eliminate the resulting backlash, as well as to improve the clarity and obedience of the steering.
Node diagram
The steering rack can be adjusted in two ways.
If the rack is removed and adjusted, we are most often talking about repairing or replacing the unit with a new one. It is recommended to carry out such settings only in these situations
Without dismantling the unit
This method of adjustment is relevant if it is necessary to tighten the rack slightly, remove play, and get rid of knocking noises. Here it is quite possible to do without dismantling work, that is, to set up the mechanism directly on the car
Malfunctions
There are several typical steering rack malfunctions that VAZ 2109 owners encounter. In some situations, simple adjustments can be done, while in others, more detailed intervention in the design of the unit and its components will be required.
Steering rack breakdowns are as follows:
- The steering rack fastenings are loose;
- The rack itself or its gears have worn out;
- Pair engagement is not adjusted properly;
- The bushings at the junction of the rack and steering rods have worn out.
It is not always possible to adjust the rack to eliminate its incorrect operation. This occurs due to the fact that an impressive production of components is formed inside. This can only be determined by dismantling. Therefore, if the adjustment does not bring the expected effect, you will have to remove the rack from the car and check what is wrong with it.

Tighten the Steering Rack of VAZ 2109
We correctly pull the control rack on a VAZ-2114 with our own hands: tips and the process itself
No one disputes the fact that a working steering wheel in any car guarantees not only the safety of the driver and passengers, but also uninterrupted operation in principle. Regardless of the type of drive, be it worm gear, rack gear or non-assisted, they all require a lot of maintenance. The VAZ-2114 and all second-generation Samara generators received a fairly reliable and familiar mechanism for managing repairs and adjustments. It does not have hydraulic booster, so it is easier to maintain and adjust.
Why pull the rail on a VAZ-2114
Diagnostics of rail control and control mechanisms
Before you tighten up the control bus on your VAZ-2114, you should consider the preconditions that will tell you when it's time to start repairs or lifting.
First of all, this is a free game.
Basically, AvtoVAZ guarantees a fairly long service life of the steering mechanism, namely ten years . However, you must understand that these are ideal working conditions. This assumes a smooth asphalt road, a constant supply of high-quality lubricant in the trunk pan and a gentle driving style.
Under normal operating conditions, this period is practically unattainable. It doesn’t matter the roads, the quality of spare parts and the often harsh conditions of the car lead to the fact that the mechanism makes itself felt much earlier.
The first symptoms of a faulty steering mechanism on a VAZ-2114
The first symptoms of a rail malfunction or the need for tightening are obvious:

2110 you will need a special octahedron key “in 17”, for a more modern one.
- Knock in the hood in the area of the engine shield, especially when driving unevenly.
On a VAZ-2114, knocking when driving on uneven sections of the road can occur due to a loose nut on the bolt that compresses the cardan clamp
The latter can be considered a glaring fault and can cause serious traffic problems.
In this case, most likely the situation cannot be corrected by an elevator, but in order to draw conclusions earlier, you can try to fix it. There are two ways to do this. both on the car and with the rack removed.
Complete disassembly of the steering rack and replacement of the repair kit
In the second case, adjustment is made after replacing the repair kit and completely repairing the mechanism. We will try to overcome a little blood and simply adjust the gap when the strut is engaged , thus eliminating play and knocking.

Most often, everything is Raising the stand. This is just selecting the engagement game and setting up the helmet game . If the wear of the mechanism parts (bushings, the gearbox itself, gears, seals and saw blades) is critical, repair and installation of the kit should not be avoided. However, the easiest way to check this is. pull the rail directly onto the car.
To adjust the strut, you will need a special wrench that is inserted into the adjusting nut in the steering gear housing. You can make this key yourself, but it is sold in any store, costs a pretty penny, and never hurts to have it in your toolbox. In addition, this will greatly facilitate the work not only when adjusting, but also when removing the rail if necessary.
The VAZ-2114 rail is adjusted as follows:
- It is recommended to install the machine either on an overpass or on an elevator. You can adjust the guide from under the hood, but it will barely work.

Video about adjusting the steering rack
When choosing a backlash, we do not hide the tool, but conduct a test drive, during which we evaluate the operation of the steering mechanism. If the steering wheel rotates freely but is not there, the adjustment can be considered complete. If the steering wheel is too tight, it is better to loosen the adjusting nut by turning it a few degrees counterclockwise.
Conclusion
The steering rack requires no less care than the steering ends
