Replacing a CV joint on a Lada Kalina: how to change it yourself

A constant velocity joint (CV joint) is a unit through which torque is transmitted from the transmission unit to the drive wheels. This device is also popularly called a “grenade”. There are both external CV joints, which directly engage the wheel hub, and an internal CV joint, which is adjacent to the gearbox. Both hinges on one side of the car are connected to each other by a metal pipe, and the entire structure is called an axle shaft. It happens that malfunctions appear, so many drivers are interested in how to change them.

The CV joint device is not particularly complicated. The unit includes a housing, a boot and a bearing, the separator of which is capable of rotating at different angles to the axle shaft, providing the ability to transmit rotation when the wheels are turned through the steering, therefore, using the tips, you can figure out on your own how to change the CV joint.

The video demonstrates the procedure for replacing the CV joint in the Lada Kalina chassis:

For models of domestic origin, including the Lada Kalina, failure of the hinge we are considering is a fairly common case. The most common factor causing the breakdown of this unit is a torn boot. This is due to the fact that dirt and moisture enter the working area of the hinge, eventually washing away the bearing lubricant, which causes wear and loss of functionality. And the outer CV joint needs to be replaced. You can do this procedure yourself.

Step-by-step algorithm for replacing a CV joint

The process should be started if there is complete confidence in the failure of the specified unit. Replacing the outer CV joint step by step if you do it yourself.

We loosen the tightening of the wheel fasteners and the hub nut (first remove the cotter pin) on one of the sides of the car.
We hang up this side with a jack and install stops under the wheels of the stern, and a safety support under the body.
We completely remove the wheel.
Unscrew the two bolts holding the ball joint to the steering knuckle bracket and the hub nut.
We turn the steering wheel of the Lada Kalina as far as possible to the side, move the axle and remove the axle shaft from the splined engagement of the hinge and the hub. If there are difficulties with the free exit of the axle shaft, then use a hammer, applying impact forces to the shaft through a drift.
When the axle shaft is released, we begin to dismantle the outer joint boot in combination with the clamps. These items must be replaced.
Now we move on to removing the CV joint. To do this you will need a special puller. If it is missing, then use the hammer again. It is forbidden to apply an impact load to the separator, so we apply gentle blows to the body in an outward direction. The joint will come off if the retaining ring compresses, allowing the cage to slide off the axle shaft.
When it is necessary to dismantle the entire axle shaft, the algorithm of actions up to point No. 7 is similar, and then, using a mount, we remove the shaft of the designated CV joint from engagement with the side gear in the transmission differential. Before such manipulation, drain the oil from the box. We take out the axle shaft as an assembly, after which we perform the necessary disassembly steps, etc.
Removing the internal hinge involves the identical procedure given in point No. 7. To make disassembly easier, we use a vice in which we place and fix the structure.

How to replace a grenade on a Lada Priora?

According to the manufacturer's advice, replacing a grenade on a Priora means installing a new front wheel drive assembly - 2 CV joints and an axle shaft on each side. Because the newest unit costs a lot of money, together with the work it comes out to a very large sum. Therefore, in practice, only the worn-out part of a given unit is replaced - the external or internal grenade, or even both. If you know how to change these parts without the help of others, you can significantly save on car service costs.

Assembly procedure step by step

We carry out the entire list of assembly operations in a Lada Kalina car in strictly reverse order. During the procedure, it is necessary to take into account some nuances.

First, we put the boot on the axle shaft. If this is difficult, then its surface can be lubricated with the grease supplied with the new hinge kit.
Now we fill the same grease into the CV joint bearing, and the remainder into the internal cavity of the boot.
We install the hinge on the axle shaft. We also use a hammer, applying a shock load to the body. The retaining ring should be replaced.
When the “grenade” “sits” in its place, we push the boot, after squeezing it with our hands to remove excess air. We install clamps.
We do the same when replacing the internal hinge.
Now we install the axle shaft into the transmission housing until the shaft engages with the side gear. Don’t forget to fill the unit with oil afterwards.
We insert the outer joint into the steering knuckle until it fully engages with the splined race of the hub. Screw on the central nut (do not tighten it).
We return the ball joint to its place.
We hang the wheel and do not tighten its fasteners too much.
We lower the car (we do not unload the jack completely). Tighten all fasteners to the required torques. We remove the jack and stops. Replacement of the outer CV joint is complete.

The owner of LADA Kalina will spend no more than 3 hours of his time to complete the full list of replacement actions. We check the correct installation of the hinges. To do this, we start driving the car with the wheels turned out as far as possible. We observe the absence of crunching and other characteristic sounds from the axle shaft. Now you know how to change a faulty CV joint.

Preparing for work

To replace grenades, you need a car lift or an inspection ditch, since part of the disassembly work is done from below. The following tools and devices will be needed:

a regular set of socket heads with a knob;
mount;
open-end wrenches;
metalworking tools, which include screwdrivers, hammer and pliers;
a device that helps press the control rod ball pin out of its socket in the rack.

If you don’t have a puller for the control rod, then it’s easy to find one from familiar car enthusiasts or just buy it, it’s cheap. This is a metal cylinder with a slot and a bottom into which an extrusion bolt is screwed. To carry out the replacement in the inspection hole, a jack with a wheel wrench is also useful to lift the car. To completely disassemble the unit, it is better to have a vice and purchase CV joint-4 thick lubricant.

How to determine a breakdown?

Limonka is a ball bearing, the cages of which have transverse grooves. Due to this, the angle between the driven and driven axle shaft changes. Thus, the CV joint not only transmits torque, but also changes the angle between the axle shafts. In view of this, over time, development is created on it. video instructions for replacing the rear wheel bearing with your own hands on VAZ cars: 2110-2112 2113-2115 2109-2108 Kalina Granta Priora. In places where the parts do not fit tightly, free movement and extraneous noise appear. In fact, this is accompanied by a corresponding crunch. It appears due to large wear on the balls that move along the grooves. The crunch can appear both during straight-line movement and when turning. In the latter case, most likely, the outer lemon of the Kalina requires replacement. This sign should not be ignored, as the bearing may fall apart at high speed.

Where is the best place to shop?

If the lemon valve in a Priora car has failed, then you need to start looking for the latest spare part. There are many places for selling such parts in Russia. Therefore, the motorist should not have any problems with the choice.

It is recommended to decide on the place of purchase in advance. In total, the owner of a Priora has three options:

Visit a store that sells Russian and imported spare parts.
Go to the car market.
Consider offers from online auto parts stores.

The choice of location depends on preferences regarding the manufacturer and financial status. If you want to purchase an unusual part from the AvtoVAZ plant, then it is better to make a purchase in a special store. Nowadays, almost everyone orders auto parts from online stores. But it is necessary to be aware of all the dangers that a motorist faces when choosing this place of purchase:

They may send you a defective part.
They may send you a used spare part instead of a new one.
They may ask you to transfer funds and not send anything.

If you want to save money and the popularity of the manufacturer is not important, then you can visit the car market. Parts from little-known companies are sold here. You may come across a Chinese counterfeit of a famous brand. Therefore, when choosing a car market as a place of purchase, you must be careful.

Varieties

CV joints are classified according to their design features into four types:

Ball bearings (more common, found in all types of rear-wheel drive passenger cars).
Paired (used very occasionally, have a complex system).
Rusks (they are mostly equipped with buses and trucks).
Tripoid (used in internal systems, characterized by axial movement).

Based on their location, grenades can be divided into two types:

External (connects wheel hubs and axle shafts).
Internal (connect the axle shafts and the box).

Depending on the design, grenades may have:

According to the manufacturer, all CV joints on Priora can be divided into two types:

The extreme ones are the cheapest. They are represented by the following brands:

There is also systematization by place of purchase of the part. According to it, CV joints are:

From an online auto parts store.
From the car market.
From a store that sells spare parts for cars.

How to extend the resource?

Typically, these bearings travel for 250-300 or more thousand km. Replacing the CV joint boot in a Renault Logan can be done either with your own hands or at a hundred; the boot can be internal or external, as well as left or right. They have a very strong construction. But there are several reasons that can significantly reduce their durability. This is the condition of the anther. It is because of this that water, dust, and sand get inside. As a result, the lubricant is converted into a thick abrasive, which has a destructive effect on the bearing. How to prevent this? During operation, you should periodically inspect the condition of the boot on the CV joint. If it has cracks or tears, it must be replaced urgently. By finding a breakdown at an early stage, we can maintain the serviceability of the hinge. It can still “walk” on a cracked boot for some time (but still not necessary, especially in wet weather).

Reasons causing breakdown

CV joint malfunctions can occur for a variety of reasons, for example, when hitting a curb, falling into a hole, etc. However, most often this unit fails due to banal damage to the boot.

The boot (corrugated rubber or silicone cover) protects the CV joint parts from dust, dirt, moisture, etc. In addition, to increase service life, the CV joint boot is filled with a special liquid lubricant made on the basis of barium. The lubricant envelops the surfaces of parts and must maintain its properties in the temperature range from -30 to 160°C.
