We change the rear struts on a VAZ-2110 with our own hands and which shock absorbers are better to choose

Rice. 1

Many owners of the “ten” are sometimes forced to do suspension tuning. Firstly, to be honest, the quality and service life of the factory suspension struts (especially the front ones, which are more loaded) leave much to be desired. Secondly, the already short-lived racks suffer most from the poor quality of our roads. Thirdly, with a very significant volume of luggage compartment, the “tens” do not have a high load capacity, so the inveterate summer resident and car traveler willy-nilly have to strengthen the elastic elements of the rear suspension.

The main requirements for the shock absorbers of the front and rear suspensions are as follows: ensuring a smooth ride, stability and controllability of the car, reducing body roll during sudden braking, reducing the possibility of the wheel lifting off the road.

As a rule, when tuning, factory hydraulic telescopic shock absorbers are replaced with gas-filled ones - single-tube or double-tube. This allows you to raise the car slightly (increase ground clearance). The vehicle's handling and stability will also improve, since on uneven surfaces, stiffer shock absorbers allow the wheels to maintain contact with the road longer. The downside of such modifications to the car is a slight deterioration in the smoothness of the ride.

When replacing shock absorbers, it is necessary to comply with the characteristics and overall mounting dimensions of the factory shock absorbers and those installed when replacing them. The suitability of shock absorbers is determined using interchangeability tables compiled by manufacturers. The main dimensions of shock absorbers are shown in Fig. 1 and in the table.

Basic parameters of shock absorbers

The entry is not entirely suitable for a BZ, but since these are still spare parts from front-wheel drive VAZs, we’ll leave it here.

On many forums you can often see that people are looking for information about how the VAZ-2108 and VAZ-2110 racks differ. I came across two front pillars that were already coming apart.

Luckily for me, one is from a VAZ-2115, the second is from a VAZ-2110. I knocked the dirt off the racks as best I could and examined them.

What is the main difference? The problem is that the body of the “tenth” rack is shorter than the body of the “eighth” one. I didn’t take the dimensions, I’ll do it later and correct the text - this is for those who are interested. And here is the rod: on the “eighth” the rebound limiter is installed higher on the rod than on the tenth, and at its “own” height. Otherwise the sizes are completely the same.

Front shock absorbers VAZ 2110, 2111, 2012

Front shock absorbers on VAZ 2110, 2111, 2012 are divided into right-hand and left-hand, gas and oil. Since the first modifications had collapsible bodies, and later solid Priorov ones, it is recommended to install front shock absorbers in accordance with their design. If you switch from shock absorber (strut) 2170 to 2110, everything will turn out to be much more financially expensive, since this will require changing such spare parts as: shock absorber (liner) 2110, shock absorber body 2110, factory nut securing the shock absorber to the body 2110, spring 2110, upper front support shock absorber 2110, spring plate 2110, shock absorber boots 2110, shock absorber bumpers 2110.

To choose a rack, you need to correctly determine its main dimensions; the data in the tables below will help you with this.

Replacement and installation of parts

If your garage has an inspection hole, install the car on it. If not, jack up the front of the car and place it on bricks or cinder blocks. Before lifting, don’t forget to put the car on the handbrake and place wheel chocks under the rear wheels!

These are the stabilizer links

The procedure is as follows:

1. Unscrew the nuts securing the stabilizer struts from the right wheel suspension, then from the left wheel suspension.
2. Unscrew the nuts securing the boom brackets on the right and left sides of the machine.
3. Remove the complete set with stands.
4. Set the original parts aside.
5. After this, it is necessary to modify the kit from Priora.
6. Take the assembled modified parts, at this point you will need the help of a friend, he will need to help with installation.
7. Place the modified rod in place, tighten the nuts securing the brackets until there is no gap in the cushion cuts.
8. Tighten the nuts securing the struts until there are no gaps between them and the arms.
9. If you raised the machine, only fully tighten all the mounting nuts when the machine is on the ground.

It is necessary to tighten the nuts of the strut with a force of 43-53 N•m, of the bracket - 13-16 N•m.

Refinement of the Priora rod is necessary because the dimensions of the engine compartment of the VAZ 2170-72 differ from the dimensions of the engine compartment of the VAZ 2113-15. When installed, the stabilizer from Priora, without a little tuning, will rest against the edge of the tunnel in which the exhaust gas system pipelines and the gearshift lever pass. When the car moves, this will cause an unpleasant creak and increased wear of the stabilizer struts.

Shock absorber struts on the VAZ-2114, like on any other car, play the role of absorbing unevenness in the road surface, and also take the load of the entire car: cargo and passengers. Therefore they must be strong. The choice of struts should be treated carefully, since it depends on them whether the car will be hard or soft, and how loud the potholes will be, of which there are plenty on our roads.

Very often, when replacing a shock absorber strut or liner, preference is given to foreign manufacturers, since their products are relatively cheap and have a high level of quality. The most popular are the racks presented in the table.

By strength

As you understand, these two elements work, as they say, “side by side.” But they have different indicators in terms of strength and wear.

The spring is a very durable element, if you don’t break it on purpose (don’t overload the car), don’t “reckless” the car when entering 90-degree turns at maximum speed, don’t fly into curbs - then it can last a very long time, there were cases when we walked 200 – 300,000 kilometers.

The shock absorber is the weaker part of the suspension, the whole point is that it is much more complex in structure, it has a bunch of O-rings, and there is liquid or gas inside. And damage to one of the elements entails failure of the entire structure. And with our roads and potholes, you can kill him for several thousand (50 - 60). This is not Europe, where they travel 150–200 thousand kilometers.

Accordingly, we change shock absorbers much more often than springs.

How to lower the Priora correctly

There are several ways to lower the landing position on the Priora. Each of them is worth dwelling on in more detail.

Air suspension

Air suspension is considered one of the best, but at the same time expensive, ways to lower a car. The driver can raise or lower the car body as necessary. In addition to the high cost of such equipment, the work must be carried out by specialists who understand the electronics and chassis of the car. Therefore, most Prior owners prefer less expensive methods of undervaluation.

Suspension with adjustable ground clearance

The Priora can be equipped with a special adjustable suspension kit. Height adjustment is carried out by means of struts, and springs with a selected lowering (-50, -70, -90) are compressed or stretched. Thus, the car can be raised for the winter and lowered for the summer. The springs that come with the kit are highly reliable and are designed to constantly change in length. The set in question consists of the following elements:

• front and rear springs;
• screw-adjustable struts and shock absorbers;
• front upper supports;
• spring cups;
• bumpers.

The procedure for implementing such a kit comes down to replacing the standard suspension elements with new ones:

1. Remove the rear shock absorbers along with the springs.
2. We install an adjustable shock-absorbing element.
3. We adjust the suspension height with special nuts, choosing the desired lowering.
4. Similarly, we change the front struts and make adjustments.

Lowered suspension

This method of lowering the suspension is less expensive than the previous one. It involves purchasing a set of shock absorbers and lowered springs (-30, -50, -70 and more.). The disadvantage of this kit is the impossibility of adjusting the ground clearance. However, you can install such a suspension yourself. To replace you will need the following kit:

• Demfi -50 racks;
• springs Techno Ressor -50;
• supports Sevi Expert.

You will also need to prepare the following tools:

• wrenches 13, 17 and 19 mm;
• 17 and 19 mm socket heads;
• breakdown;
• hammer;
• pliers;
• ratchet handle and knob;
• penetrating lubricant;
• spring ties.

Replacement of suspension elements is carried out as follows:

1. Apply penetrating lubricant to the threaded connections of the front struts.
2. Using sockets 17 and 19, unscrew the fastening of the struts to the steering knuckle.
3. Unscrew the ball pin nut and unscrew it.
4. Using a hammer and a pry bar or puller, press the ball pin.
5. Unscrew the upper support of the rack.
6. Remove the stand assembly.
7. We install springs and support bearings on new struts.
8. By analogy, we change the rear pillars, unscrewing the upper and lower fastenings and installing new elements.
9. We reassemble in reverse order.

Low profile tires

One of the options for lowering the suspension of the Lada Priora is to install low-profile tires. The standard tire size for the car in question has the following parameters:

• 175/70 R13 82T;
• 175/65 R14 82Н;
• 185/60 R14 82Н;
• 185/65 R14 86H;
• 185/55 R15 82H.

When lowering the seating position by installing low-profile tires, a small deviation from the standard dimensions should be maintained. Otherwise, the vehicle's performance may deteriorate, which will negatively affect not only driving performance, but also the wear of suspension elements.

Filed the springs

One of the most budget-friendly ways to lower the suspension is to shorten the springs by cutting off a certain number of turns. To carry out such an upgrade you will not need to buy anything. It is enough to arm yourself with a grinder. The procedure consists of dismantling the shock absorbers and springs, followed by the removal of 1.5–3 turns. You can cut off more, the car will become lower, but the suspension will practically not work

Therefore, such experiments should be carried out with caution.

Which racks for VAZ 2110, 2111, 2112 are better?

What shock absorbers are better to install on the VAZ 2110-2112? It's hard to call the factory struts good for this car. According to technical parameters, they are suitable for average use. But they will not provide the desired efficiency and duration of operation with other styles of operation.

With a calm, even ride on decent city roads, hydraulic (oil) shock absorbers will create the greatest comfort and smoothness. Their main advantage is the price, and the disadvantage is their rigidity in winter. And if the road surface is full of holes, then they will not suit you at all. Gas struts are chosen by those who like to drive fast and off-road (by the way, the ground clearance will increase a little) while sacrificing comfort. The main disadvantages are: cost and increased shock loads on suspension parts and the body. But the golden mean is gas-oil - for fast driving on any roads. They are able to maintain sufficient comfort no matter how you drive the car. But despite all the pros and cons of shock absorbers, they very often use oil rear and gas-oil shock absorbers, or also “oil” shock absorbers for the front suspension

Among the foreign brands that have gained popularity among car enthusiasts are:

MONROE REFLEX – the advantages of this shock absorber include reliable and high-quality production of rods. Good car control, especially when cornering, does not throw the car. At first they behave rather harshly, then over time they become smoother.

KAYABA PREMIUM is one of the best oil shock absorbers, giving the car moderate softness and the ability to absorb all bumps on the road. Disadvantages include failure of the valve compression stroke mode at high speeds, the lack of boots included in the kit to protect the rods from moisture and dirt, and the lack of operating instructions in Russian.

Varieties of SS20

SS20 support diagram
Usually cars are equipped with standard medium stiffness, but some people want more comfortable ones or, on the contrary, stiffer ones.

The SS20 offers three options.

1. Racing. A sports modification of racks that have a shortened stem and body. The car is slightly lowered, rolls become softer, and stability is higher. The car feels better in turns, maneuvers well at high speeds, and improves handling quality.
2. Master. This series of racks is suitable for those who want to reduce noise while increasing flexibility. It is much easier to operate a car with them.
3. Queen. The load is distributed evenly due to the design of the products. The racks dampen noise and demonstrate high reliability. The warranty period for these racks is 3 years.

Method three: Air suspension.

Lada Priora with air suspension.
This method is the most expensive and difficult to install. To install the air suspension, the car must be completely disassembled. Install special equipment; besides, air suspension is not suitable for cold seasons. Quite often it happens that condensation appears in the tubes, which in cold weather can lead to a blockage in the air channel.

To install this method of understatement, qualified specialists will be required. Large set of tools and equipment. To install the air suspension you will need: a receiver, a compressor, hoses, pipes, special racks, sleeves, etc.

The installation of air suspension has not found much popularity due to its high cost and capriciousness. Due to the large amount of reagents on the road, air leaks often appear in the system, which makes it impossible to drive a car. Also, using a car in winter is quite problematic.

Advantages and disadvantages of air suspension

Pros of air suspension:

• Possibility of changing clearance

Disadvantages of air suspension:

• High cost and complexity of installation;
• Inability to move in cold weather;
• Taking away useful space in the trunk;

What else should you not do?

However, many of our “VAZ DRIVERS” don’t care at all; I’m already silent about the lowered Priors. When repairing suspension, and in particular replacing struts, many people prefer not to change other elements, even with high mileage.

I personally witnessed when a guy took the KYB struts, came to the service station, and said, “we leave the springs and support bearings (after a mileage of about 80,000).” Simply - HARD! Guys, turn on your brain. Companies do not always have interchangeable parts, even new ones! That is, you cannot take a KYB strut and install a spring from a VAZ supplier, this is no longer correct, and you are installing a new shock absorber on worn parts!

In the best case, the rack will fail in 10 - 15,000, and then this GUY will shout at every intersection that “I installed KYB, such a g..but!”

In the worst case, there is a possibility that it will fly off the road, because the sagging, tired, corroded “coils” will not be able to properly hold the car and dampen the amplitude of body vibrations. Which negatively affects maximum speeds, cornering, and braking. The body will pull more to the sides during maneuvers.

Therefore, the moral is not to save money, we buy a completely new set.
