The ball joint is the most important element of the front suspension of a car. It allows you to perform basic control functions, turns and provides stable movement in a straight line. The design of the part ensures that the wheel is fixed in the vertical plane and rotates freely in the horizontal plane when turning. The ball joint was invented 40 years ago by an Italian engineer from the Fiat corporation, and its design has remained almost unchanged all this time.
Ball joint Lada Largus - device
The ball joint on the Lada Largus is a non-separable part, consisting of a one-piece cast body, pin, boot and polymer liner. In the ball device you can also find pressure washers that serve as clamps. Below you can see what the ball joint looks like in cross-section.
When you fall into a hole or run over an uneven surface, the polymer liner of the ball joint takes the entire impact and wears out over time. When a gap occurs between the body and the ball pin, the ball joint begins to play and makes a characteristic knock when driving on an uneven road.
Ball joint Lada Largus article number (401604793R, 8200298455)
Two types of ball joints were installed on the Lada Largus. They differ in the method of fastening, namely with a finger. On some, the finger has a cut in a circle, and on others - only in one place. How do you know which ball joint is needed?
If the car was manufactured from 2012 to 2014, then you need to buy a ball joint with article number 401604793R. It looks like this:
Cars from 2014 to the present have been equipped with ball joints with article number 8200298455. This ball joint has a slightly different cut in the pin for bolt fixation.
If you have a transitional model from 2014, then it is difficult to say for sure which ball joints are installed on your car. The easiest way is to remove the ball and select a similar one in the store.
Ball selection, articles
In many ways, the operation of the car depends on the choice of spare parts for the suspension. Since the ball joint is responsible for the angle of inclination of the wheels at the moment of movement, the selection of this part must be taken seriously.

Replacing the ball joint Lada Largus
The first step is to remove the wheel bolts from the front wheels and jack up the car. Be sure to place wheel chocks under the rear wheels.
Next, unscrew the bolt from the steering knuckle to remove the ball joint pin. The seat may rust, so we spray everything with penetrating lubricant and, if necessary, clean everything with a wire brush.
Unscrew the stabilizer bar bolt and the two rear lever mounting bolts.
We take out the lever together with the ball joint and proceed directly to replacing the Lada Largus ball joint.
It is necessary to remove the old ball joint from the lever. There are two ways to go. Either simply knock out the ball with a hammer (quick and easy), or press it out using a vice or garage press (not fast, but easy). Since this ball is no longer required to be reinstalled, I try to choose the easiest way - knock out the ball with a hammer.
But before that, you need to remove the ring stopper. Just pry it up with two flathead screwdrivers and remove it.
We rest the edges of the lever against a pipe of the appropriate diameter and knock out the support with a sharp blow into the ball rod.
We clean the mounting hole of the ball joint in the lever from rust with a wire brush.
We unpack the new Lada Largus ball joint and begin pressing. We do not remove the protective cap of the ball joint until the ball is installed in the lever.
Using a press or vice, press the new ball into place until it stops. Don't forget to put the stopper in place. We do this without removing the protective cap so as not to damage the boot.
Important! Do not press or drive the ball through your finger! In this case, you can damage the polymer liner, which will lead to rapid failure of the entire assembly.
We assemble the lever in the reverse order. If it is necessary to replace the ball joint on the second side, then we perform a similar procedure.
Ball support with circular groove for VAZ Largus
Dear customers, in order to avoid mistakes when sending a ball bearing with a circular groove to the lower front suspension arm of the Lada Largus / LADA Largus produced before June 2013, in the “Comment” line indicate the ball bearing with which groove is lateral or circular, the model of your car, the year of manufacture.
The front suspension of the Lada Largus / LADA Largus is independent, MacPherson type, with triangular wishbones and a stabilizer bar.
The basis of the suspension is a telescopic shock absorber strut, which allows the wheels to move up and down when driving over uneven surfaces and at the same time dampen body vibrations. The rack is attached from below with two bolts and nuts to the steering knuckle, and from above - with a nut through a rubber-metal support to the body.
1 – lever; 2 – subframe; 3 – bolt securing the lever to the subframe; 4 – anti-roll bar; 5 – bracket for attaching the stabilizer bar to the subframe; 6 – shock absorber strut; 7 – steering knuckle; 8 – elements for fastening the stabilizer bar to the lever; 9 – coupling bolt of the terminal connection of the steering knuckle and the ball joint pin; 10 – ball joint
To effectively dampen body vibrations and improve the controllability and stability of the Lada Largus / LADA Largus car, a double-pipe gas-filled shock absorber is installed in the strut body, which has higher characteristics than a conventional hydraulic shock absorber.
The lower spring support cup is welded to the middle part of the strut body, and a bracket for attaching the strut to the steering knuckle is welded to the bottom of the strut.
A compression stroke buffer is installed on the shock absorber rod, made integral with the protective cover. From above, the spring rests against the upper support cup mounted on the shock absorber rod. A thrust ball bearing is installed between the upper spring cup and the upper strut mount, allowing the strut body to rotate with the spring while the shock absorber rod remains stationary.
Braking and traction forces when driving a Lada Largus / LADA Largus are perceived by suspension arms connected through ball joints to the steering knuckles and through silent blocks to the subframe.

The ball joint 401604793 with a circular groove is the most important element of the front suspension of the Lada Largus / LADA Largus. It allows you to perform basic control functions, turns and provides stable movement in a straight line. The design of the part ensures that the wheel is fixed in the vertical plane and rotates freely in the horizontal plane when turning. The ball joint was invented 40 years ago by an Italian engineer from the Fiat corporation, and its design has remained almost unchanged all this time.
The ball joint on Lada Largus models produced before June 2013 had a pin with a diameter of 16 mm and an annular groove.
In the supports that are installed on new models, the pin diameter is 18 mm, they have a side groove.
Ball joint 401604793 with a circular groove is very important in the design of the Lada Largus / LADA Largus car. It adjusts the angle of the wheels. Damage to the support becomes a significant problem, since if it falls out on the road, it can cause damage to other elements of the car, and further movement will become impossible.
Experts recommend removing the lever to replace this part, but this is not necessary.
Diagnostics of the ball joint Lada Largus / LADA Largus:
- 1. You need to pay attention to the condition of the boot. If it has cracks or is torn, then it must be removed and the ball should be inspected.
- 2. Suspend the wheel a little and rock it up and down with your hands. If there is play, the ball joint needs to be replaced.
- 3. The presence of a squeak, as well as heavy turning of the steering wheel, can also be signs that the ball joints are in critical condition.
- 4. Instability in control, namely departure from the trajectory of movement to the left or right, with the steering wheel in a level position, indicates that the ball joint is out of order.
The ball joint consists of a main load-bearing element - a pin made of high-carbon steel. On one side there is a sphere, and on the other there is a groove for mounting with a steering knuckle. The spherical part of the finger is located in a metal case filled with polymer, which dampens vibrations and shock loads when the car is moving. The support body is pressed into the suspension arm, and a boot is placed on top of it to prevent dirt and dust from entering.
Ball joints are subjected to heavy loads, so stringent requirements are placed on their design and manufacturing technology. The support pin must withstand a force of up to 5 tons to be pulled out of the body. To ensure the high quality of this important unit, GOST 52433-2005 “Ball joints. Technical requirements and test methods”, which should guide both Russian and foreign manufacturers.

545009976R — right front suspension arm assembly (ball with side groove and salen blocks) Lada Largus / LADA Largus.
The subframe is rigidly attached to the body with four bolts, two rear bolts also secure the stabilizer bar brackets to the subframe. On the front bolt securing the suspension arm to the subframe, a bracket is secured with a nut, the second end of which is attached to the body.
The ball joint housing is pressed into the hole in the suspension arm, the support is covered with a rubber boot. The ball joint pin is secured with a clamp connection to a coupling bolt in the steering knuckle eye.
A closed-type double-row angular contact ball bearing is pressed into the hole of the steering knuckle, and the wheel hub is pressed into the inner rings of the bearing.
The inner rings are tightened (through the hub) with a nut on the threaded part of the shank of the outer wheel drive joint housing.
In operation, the bearing is not adjustable and does not require replenishment of lubricant. On a Lada Largus / LADA Largus with ABS, the front wheel speed sensor master disk is one of the two wheel bearing protective washers.
Wheel bearings for Lada Largus cars with and without ABS are not interchangeable. The hub bearing nuts for both wheels are the same, with right-hand threads.

How long do ball joints last on a Lada Largus?
Ball joints on Lada Largus are consumables that require constant inspection and periodic replacement. This is not to say that this is a weak unit that constantly fails.
In general, the chassis of the Lada Largus was borrowed from the Renault Logan, which was very, very good in terms of suspension reliability. Pay attention to taxi drivers who choose Renault Logan for work. Believe me, taxi drivers will not buy a brittle and damp car in order to constantly bother with its repair.
If we summarize the reviews from various forums and information sources, the ball joints on the Lada Largus last approximately 50-60 thousand km, after which they require replacement. Of course, there are isolated cases when ball bearings have traveled more than 100 thousand km, but this is most likely an exception to the rule than a pattern.
Here, not only the quality of the part plays a big role, but also the driving style. If the car is used by a careful driver and mainly in the city, then the ball joints last much longer. If the car is often used on bad roads, and even by not the most careful driver, then the ball joints will require replacement much earlier.
Ball joint with lever Lada Largus
There is an opinion that Lada Largus ball joints only come assembled with a lever. And many car owners change the lever assembly. This costs much more than replacing one ball joint.
However, in some cases, for example, if both rear silent blocks on the lever are torn, you can think about replacing the lever assembly. Most often, this is easier than replacing complete silent blocks and does not always cost more.
It happens that the mounting hole for the ball breaks and the only correct solution is to replace the lever assembly.
To order a ball joint with a lever for Lada Largus, you can use the following article numbers:

Diagnostics of the ball joint condition
Symptoms of the need to pay attention to the Largus ball joint are:
- there was a need to apply additional force when turning the steering wheel;
- driving over bumps, for example, a speed bump, is accompanied by a knocking sound from the front suspension;
- Uneven tire wear was detected;
- entering a turn is accompanied by extraneous sounds coming from the wheel arches;
- the steering wheel turns with a creaking or grinding sound;
- the car has become less obedient when entering a turn;
- When driving over bumps, controllability partially decreased and the car became unstable.
If you have the above symptoms, it is recommended to use the following algorithm for finding a ball fault.
- Hang it in front of Largus.
- Take the tire from above and below.
- Check that there is no play. To do this, you need to shake the wheel in a vertical plane. It should be borne in mind that the cause of movement may be not only the ball joint, but also worn steering tips or stabilizer links.
The main load-bearing element of the ball joint is the pin. It is made of high carbon steel. On one side of the finger there is a sphere, which is located in a metal case. It is filled with polymer or grease. To prevent moisture, dirt and dust from entering, a protective cuff is placed on top.
Abrasive particles and water pass through the boot freely if it is damaged. The sphere and its seat are subject to intense wear, and the lubricant dilutes and ceases to perform its functions. Therefore, when diagnosing a ball, it is important to pay attention to the condition of the boot. If cracks, punctures, holes or other holes are found, the support must be replaced.
Lada Largus ball with side groove
Ball joints on Lada Largus before 2014 and after are distinguished by the shape of the side groove on the pin. The ball body is no different, but the fingers differ in the shape of the side groove.
Until 2014, the side groove of the Lada Largus ball had this shape:
After 2014 and to the present time, the ball joints of the Lada Largus (van, crossover, station wagon) have the following side groove:
Accordingly, the Lada Largus ball mounting bolts before and after 2014 are different.
Article number and price for the original ball joint
On the Lada Largus car, two types of ball joints are used. Until June 2013, the knot had a finger with a diameter of 16 mm. An annular groove was made on the support. The article number for the old-style ball is 401604793R. The price of the part ranges from 680 to 850 rubles.
In the 2014 model range, new types of supports began to be used. The diameter of their finger was increased to 18 mm. The groove has also changed. It became lateral, which, according to the designers, increased the reliability of the unit. The catalog number of the new ball is 40160-2523R. The cost of the support is 500-1400 rubles.
Despite the fact that ball joints of different years of manufacture are successfully pressed into seats instead of each other, experienced car owners do not recommend doing this. Using a “foreign” support may cause a knock in the suspension, and a number of difficulties will arise during installation.
The balls are fixed using a bolt with an increased diameter inside. The old and new type support mounts are not interchangeable. When purchasing an unsuitable unit, car owners have to bore a groove for the bolt, which does not have the best effect on the reliability and safety of the suspension.
Repair of ball joint Lada Largus
If the Lada Largus ball joint is out of order and starts knocking, then it can be repaired. This is done as follows. A hole is drilled on the back side of the ball and a thread is cut into it. Next, molten polyamide is pumped through the hole. After which a special plug is screwed into the hole.
But due to the low cost of a new part, this procedure is not justified. Therefore, it is faster and cheaper to replace the ball joint with a new one.
