How to remove a grenade on a VAZ 2110 - useful tips from mechanics

Replacing an external grenade on a VAZ 2110 can be a serious problem if you don’t have some special tools at hand. However, for every non-standard situation there is a non-standard way out. How to change a grenade on a VAZ 2110 quickly and without difficulty is in the article.

To begin with, what is a CV joint? This is the correct name for the grenade, the second is a popular name, due to the specific shape of the part. There are 6 bearings installed inside it, on which the inner race rotates. Therefore, torque can be transmitted to the hub at any angle.

Tools for replacing the external CV joint of Lada 2110

There are several specific tools here that you can’t do without. To begin with, you need a 32mm socket, as well as a huge lever to unscrew this very grenade.

Next you will need something like a reverse hammer. The weight of the cargo is about a kilogram. If it is not there, then we will go along the second path, we will describe it below. You will also need a device for removing and installing clamps, either pliers, or just a screwdriver, we’ll talk about this a little later.

We change a grenade on a VAZ 2110 without removing the drive

This is the first, shortest path, which implies the presence of all the specified tools. Everything is quite simple.

• Before jacking up the car, you need to unscrew the grenade nut. To do this, we seat the assistant in the cabin; he must press the brake pedal with all his might and hold the steering wheel. In order to unscrew a grenade after a conscientious tightening, you need a lever of about a meter, sometimes more. The threads are usual everywhere, right-handed.
• Then we remove the wheel bolts, jack it up and remove the wheel.
• We unscrew the two 17mm bolts that hold the ball joint, disengage the splines, and move the hub to the side.
• Now, using a tool for removing clamps or a screwdriver, depending on the type of clamp, remove it. Don't forget about the small clamp.
• Now we screw the reverse hammer with a welded nut onto the grenade. We clamp the drive with a gas key so that it rests against the forged lever (saber). This is necessary in order not to tear the drive out of the box, otherwise you will have to take the second path. With a sharp blow we rip the grenade off the slots.
• We remove the boot; as a rule, the grenade fails precisely because it has broken through.

Important! Under no circumstances should you install the anthers that come with the grenade. They are made of very low-quality rubber, become tanned at the slightest cold snap and burst. Therefore, you will soon have to change the grenade again.

• We install a new boot. We do this very carefully, preferably after washing the slots first. The main problem is the thrust ring; carefully throw the boot over it with a screwdriver.
• Now we tighten the inner clamp, screw the new grenade onto the hammer, and then hammer it into place. Theoretically, this can be done with a hammer through an old nut; knocking a grenade down with a hammer is also possible, but there is a risk of damaging the slots if you are not used to it.
• We take CV joint lubricant, it is usually included in the kit. We squeeze it out in a circle onto the balls, removing the boot and turning the grenade inside out.
• Next, tighten the clamp.
• We put everything back together in reverse order.
• It is very important to tighten the nut just as tightly and be sure to tighten it.

"Grenade" defects

Before replacing CV joints on a VAZ 2110, you need to make sure that they are made with high quality and can effectively perform their job in a new place.

Alas, sometimes replacing the inner CV joint on a VAZ 2110 does not give the expected result, since product defects appear during manufacturing or installation.

The literature indicates that CV joints are made from special high-strength alloys that practically do not wear out. But in practice everything looks a little different. Whatever one may say, there are no eternal parts, and CV joints are no exception.

Defects may be as follows:

• Low quality of alloys used in manufacturing;
• Banal fakes and defective components;
• Poor quality or complete lack of lubricant, which leads to rapid failure of even a new grenade;
• Damaged anthers, due to which all kinds of debris get into the grenade.

Regarding the replacement of CV joint boots on a VAZ 2110, we recommend watching a video that will help you cope with the problem that has arisen. This issue should be approached thoroughly.

Types of clamps on the CV joint boot

Now it’s time to talk about what kinds of clamps there are, how to deal with them, and which clamps for the CV joint boot are better?

First type

Let's start with the most popular. This is the so-called “Ford” clamp. Recently, it can increasingly be found in kits from various manufacturers of grenades for the VAZ 2110 and other domestic cars. Among its advantages, of course, is the full connector, that is, if you accidentally forget to put it on in advance, you can do it at any time. Besides, you can’t “pull him over.”

Among the disadvantages, of course, is its disposability; you can use it a maximum of 2 times. Many may think that there is always a new one in the kit, but they would be extremely mistaken. It also happens that he is not there. Anything can happen.

To install it, you will need pliers or regular bokoser-nippers. We just tighten it as much as we can with our hands, then squeeze it.

Second type

These are purebred Chinese clamps. As soon as you see them, you will immediately understand why there is such an opinion about them. These clamps are simply made almost from foil. That is why they are tightened in two turns. To install, simply place a screwdriver into the plastic to avoid turning, then tighten, bend, bend the antennae, and cut off the excess.

The advantages include ease of installation; absolutely no tools are needed except a screwdriver. Well, the downside, as with the previous option, is that it is disposable, since after installation you will have to cut off the extra tail of the clamp with scissors.

Third type

The third type can only be found on grenades for domestic cars. On the one hand, they are the most convenient, since they are made of thick metal, which, by the way, is quite soft; installation takes about five seconds. It can be installed at least 10 times, it all depends on accuracy. Of course, there is one drawback - the need for a special clamp, the cost of which is several times higher than the cost of replacement at a service station. Of course, if you plan to buy only the same grenades, then you can buy the necessary thing.

Which CV joints should I buy?

It is worth keeping in mind that the highest quality components are considered to be factory parts marked VIS or Lada IMAGE. It is these brands that mean factory original parts produced by AvtoVAZ.

Their price, of course, is not the lowest and ranges from 900 rubles for one “grenade”, but you should not save on this, because the price of the work can also be decent and you are unlikely to want to change it all again every month.

But there are owners who are accustomed to repairing their cars with their own hands, and among VAZ 2110 lovers there are many of them.

Replacement of outer CV joints (grenades) without removing the entire drive. Instructions

To work, you need a garage, but if you wish, you can do it outside. A good jack, rags, a 30mm head and a wrench, 17 and 19mm wrenches, a hammer and a set of CV joints. A puller for steering tips, VD-40, a flat-head screwdriver, pliers , a knife. And also hard wire. 1. We put the car at speed and, if possible, use the handbrake. We fix the three wheels with rollback wheels or bricks. 2 We remove the protective plastic cover from the hub, if possible, align the wrapped hub nut and unscrew it with a wrench and a socket by 30. Let me tell you straight away that it will not work easily. 3 We lift the wheel with a jack, for self-confidence we also put some kind of timber; it’s dangerous to place bricks, they can burst. We remove the wheel. 4 You will need to remove the caliper and hang it. The caliper is held in place by two bolts, use a 17 wrench to unscrew them. 5 Unscrew the two fastening bolts with a ball wrench at 17!6 It will also be necessary to pull the steering tip pin out of the front strut. Remove the cotter pin from the steering tip nut fixation hole and then unscrew the nut with a wrench at 19. Use a puller to remove the pin from the strut. And now you can remove the old CV joint from the hub by pulling the strut towards you and moving the rack to the side.7 Now the CV joint is free, remove the two clamps securing the boot. Cut the boot with a knife and throw it in the trash.8 Using a rag, remove the old grease from the drive and CV joint and use a hard wire to the stationary part of the suspension so that the drive does not jump out. Take a hammer and We knock down the CV joint with one good blow. Remove the retaining ring for fixing the CV joint. This is complete with dismantling the outer CV joint. Then everything is done in reverse order. I HOPE THE INSTRUCTIONS WILL BE INTERESTING TO ALL OWNERS OF FRONT WHEEL VASES!

Replacing a grenade on a VAZ-2110, 2111, 2112

The car drive part responsible for transmitting torque from the gearbox to the wheel is called a CV joint (constant velocity joint) or is also called a grenade due to its external similarity.
The CV joint is a ball bearing that rotates transversely rather than longitudinally. Despite its simple design, the hinge performs a very important function in the vehicle’s chassis system.

The grenade normalizes the constantly changing angle of the axle shafts connected to each other, which allows the front wheels to freely turn left and right.

There are two CV joints in one car:

1. The internal one is designed to transmit rotation from the gearbox to the shaft.
2. The external one transmits rotation from the shaft to the hub.

Functionality check

The condition of the inner and outer CV joints should be examined separately, since the procedures and symptoms are somewhat different.

External grenade

The most obvious and main sign of wear of this element is the appearance of a sound similar to a crunch. It appears because the grooves have worn out and the balls do not move along them as well as before. The crunching becomes noticeable when entering turns, sharply pressing the gas pedal or passing difficult road sections.

Grenade

If you want to verify that the outer CV joint is faulty, do the following:

• When starting from a standstill, deliberately create jerks, but not strong ones;
• Try to accelerate sharply and slow down;
• Move the shaft transversely between the CV joints. If you feel any play, then the grenade is definitely worn out.

Internal grenade

It is noteworthy that the internal hinge is more durable and less subject to wear. Most often, the inner CV joint declares its malfunction when simply driving in a straight line or when passing through difficult sections. A check for play, similar to an external grenade, will allow you to verify problems.

But to understand whether an element really needs to be replaced, do this:

• Raise the drive wheels, which will allow you to bring the inner CV joint to its maximum angle;
• Start the engine;
• Turn on first speed;
• If the hinge is at the limit of wear, you will hear a characteristic crunch. This is a signal that you need to change the grenade.

Basic faults

The most common failures of a grenade include: failure due to contamination and due to wear of the part (end of service life or defect).

A faulty grenade can itself reveal its unsatisfactory condition in the form of crunching sounds, crackling sounds when turning wheels, and body vibrations. But in this case, you will have to buy a new part, but you can notice the malfunction much earlier (at the stage of damage to the cover) and prevent serious repairs.

There are several ways to identify a breakdown:

• shake the drive shaft with your hand. If play is detected, the element should be replaced;
• Turn the steering wheel all the way to the left, and then to the right, and at each stage assess the condition of the anthers. If damage (cracks, breaks) is detected, replace them.

The CV joint is protected by anthers from getting dirt into it, which disables the part. But their service life does not last forever; regular inspection of these parts is necessary (as described above) to prevent more serious damage to the grenade.

When operating a car with a faulty joint, also known as CV joint, there is a high probability of it breaking in half. In this case, the vehicle will not be usable. This means repairs will be required and most likely (if this happens on the road) expensive tow truck services.

It is recommended to replace the grenade in a timely manner to avoid unpleasant situations.

Price

An internal CV joint will cost an average of 1,500 rubles, an external CV joint will cost 1,300 rubles. For the anthers they will ask about 150 rubles each. Replacing anthers will cost much less.

Replacing CV joints at a car dealership will cost 1,200 rubles (600 rubles each).

It is recommended to buy a new part using an old one, so the likelihood of an incorrect purchase is minimized. In addition, the purchase of CV joints should be carried out in trusted stores. You should not buy these parts at a disassembly site; it is possible that a breakdown will occur within a few meters.

Determination of CV joint failure and causes of failure

Faulty grenade VAZ 2110

Before starting the process of replacing a grenade, it is recommended to determine which grenade needs replacement. Simply feeling the shaft play on the overpass is an accessible method for determining the malfunction of a particular grenade. As a rule, a working grenade should not create any play at all.

Note. It is worth noting that a faulty grenade does not necessarily occur on older cars. This situation is often observed when the CV joint fails on a car that has recently left the assembly line.

What are the main reasons why a grenade fails? Here they are, listed below:

• the quality of the grenade, which can be low or high (often a fake is sold instead of the original part or a defect is established);
• lubricant that is either completely absent or available in insufficient quantities;
• failure of the boot (see How to replace the boot on a vase), which leads to damage to the grenade (the boot is protection and if it is missing, various abrasive debris and water get into the grenade mechanism);
• incorrect driving style (aggressive driving style);
• poor condition of roads (especially important here in Russia).

Worn CV joint

So, you can determine the malfunction of the CV joint yourself, as mentioned above, by detecting play in the shaft. In addition, the malfunction of a grenade, like any other part or mechanism of a car, is caused by a change in properties, dimensions, formation of a hole, etc. As mentioned above, the grenade is a hinge, the structure of which contains elements that rub and are under constant load. If the CV joint is a kind of bearing, then its races must have transverse grooves. This is what allows you to change the angle between the drive and driven axle shafts. Since the grenade, forcing the car to move, transfers significant force to the wheels, over time it loses its performance and wear is formed on the part. It also increases the gap. And where there is no close contact between mechanisms and parts, knocking, noise, etc. occur.

Torn boot on a VAZ 2110 grenade

The appearance of a characteristic crunch when turning the wheels is the main sign of failure of the grenade, which most experienced drivers know about. Such a sound can only be produced by metal balls rolling along the gutters.

Note. Such a crunch can appear at any time, but, as a rule, when turning the wheels or sharply accelerating from a standstill. In addition, a characteristic sound may appear when overcoming obstacles.

Slight jerks when the car starts moving will also help to identify signs of a CV joint malfunction. Also, experts recommend changing driving dynamics to quickly identify faulty grenades. As was said, there are two types of grenade: external and internal. How to determine the malfunction of an external grenade, or as it is also called an external grenade, was indicated above.

Note. The external CV joint differs from the internal one, first of all, in that it is smaller in size and fails much more often than the internal CV joint.

So:

• To determine the malfunction of the external grenade in another way, you need to turn the steering wheel and move away. If the grenade is faulty, it will begin to “crunch”.
• To determine the malfunction of the internal grenade, you will need to drive not in a curved manner, as when checking the outer CV joint, but in a straight line. The internal grenade will especially clearly signal with a sound signal that it is time to replace it when overcoming holes, snowdrifts or shallow ditches.
• You can finally check the malfunction of the grenade on the lift. The front wheels will be suspended and if the CV joint is faulty, a characteristic crunch will appear.

Replacement

It is recommended to drive the car onto an inspection hole or overpass, put the handbrake on, engage the gears and support the rear wheels with wheel chocks to ensure safety during repairs.

We arm ourselves with the following tools: wrenches 17.19, socket 30 and 13-17, mount, wheel wrench, wrench, lift (jack), lubricant and pliers.

Both hinges, internal and external, are located on the shaft drive, which means replacing them is identical and the point is to get to this very drive.

1. At the rear on the crankcase protection we unscrew two nuts with a 19mm wrench, and at the front there are also two, but with a 17mm wrench.
2. Drain a little oil (less than half) from the box.
3. From the required side we tear off the wheel bolts with a balloon.
4. Unscrew the nut of the outer grenade using a 30mm socket.
5. We lift the vehicle using a jack.
6. We remove the wheel by unscrewing it first.
7. Find the bolts on the hub that secure the CV joint and unscrew them using a 13mm wrench (only two bolts).
8. Use a pry bar to move the hub away from the reaction rods.
9. We take the grenade pin out of the hub, to do this we pull the stand towards ourselves.
10. We move the shaft drive aside.
11. Now you need to remove the inner hinge from the box. To do this, open the hood and, using a pry bar inserted between the parts, jerk it towards the box. The CV joint must move, otherwise we repeat the action. As soon as it works, we go down to the wheel arch and remove the shaft drive with two CV joints.
12. Remove the clamps (large and small) of the protective cover from the hinges. If damage to the anthers is detected, we replace them; if the condition is satisfactory, we move them to the side.
13. Using a hammer, we hit the inner clip of the inner grenade with force, making sure that it flies off. We repeat similar actions on the other side.
14. We remove the old rings from the shaft drive, put on new ones and a boot.
15. We install the new hinge using a hammer and lubricate it and the boot with grease.
16. Using clamps, we fix the protective cover on the grenade and the shaft. We do the same with the second part.
17. We drive the shaft drive into the box, having first screwed the nut onto the CV joint.
18. We collect spare parts in reverse order.

Kinds

In a VAZ 2110 car, the CV joint may need to be replaced. But which one exactly? After all, in the “ten” there are two of them - internal and external. They are necessary in order to effectively overcome all obstacles. Here one CV joint will clearly not be enough.

Internal and external

1. The first grenade is internal, and it transmits torque to the shaft from the transmission.
2. The second grenade is external and engages with the car's wheel hub.

Despite the fact that their operating principle is the same, they differ in design and price.

Replacing CV joint VAZ 2110

A “grenade” or CV joint is a ball bearing with transverse rotation. On all front-wheel drive domestic VAZ cars, including 2110-2112, the front wheels rotate using constant velocity joints - CV joints. Thanks to it, all the torque that comes from the engine to the gearbox is transmitted to the front wheels; This part is used exclusively in front-wheel drive vehicles.

The grenade normalizes the constantly changing angle of the axle shafts connected to each other, which allows the front wheels to freely turn left and right. And it is these nodes that are subject to increased wear.
