Ball support "Lada Largus": description, possible malfunctions, replacement. Restoring ball bearings

"Lada Largus" is a Russian wagon,built on the basis of "Renault Logan". The machine has been serially manufactured since 2012. The wagon has a classic suspension scheme, where MacPherson struts stand in front. For the implementation of the rotation of the wheel in the design also provides a ball bearing. Lada Largus is equipped with this element at the top and bottom of the hub. What is this part, what are its faults and how to replace it with your own hands? All this you will learn in our today's article.

Characteristic

An integral part of the chassis of the car"Lada Largus" - ball joint. This part is the link between the steering wheel and the triangular suspension lever. Element helps rotate the hub in different positions. The part itself has a conical shape with a ball tip (whence such a specific name), which simultaneously swings and rotates. Thus, the Lada Largus ball bearing ensures that the hub rotates, keeping the wheel itself in a horizontal plane. In this case, the disk can move freely in a vertical position (when the machine falls on a pit or any other unevenness).

Possible malfunctions

In 90 percent of cases, the cause of failureThe ball bearing is contained in an untight boot. It is a small piece of rubber covering the joints. Over time, the anther cracks and cracks. As a result, water and dirt get inside, acting like an abrasive. Also in the support are formed and corrosion processes, which significantly reduce its life.

The next cause of failure is natural.wear. The service life of the Lada Largus ball bearing with side groove is from 150 thousand kilometers. This is a very reliable and hardy knot. But over time, he loses his strength. The part is charged with the load from all over the car. It is at this point that the entire mass of the vehicle is concentrated (at least its front end). At the junction of the articular junction, the element may break (especially if the quality of the road surface leaves much to be desired). Also at the junctions of the surfaces, generation is formed. This increases the gap between the part body and the finger. As a result, the Lada Largus ball bearing stops holding the wheel in a horizontal plane.

Instruments

To perform the operation to replace this part, we need:

  • Balonnik.
  • Jack.
  • Torque wrench.
  • Thick slotted screwdriver and small hammer.
  • Spanner wrenches, as well as the head "at 16", "at 18".

Getting Started

So, how is the replacement of the “LadaLargus? First we need to loosen the mounting bolts of the wheel itself (if there are “sekretki”, unscrew them too). Next, hang out the front of the car, using the jack. After that, disconnect the fasteners rod stabilizer bar. If there is a metal engine protection, remove it.

Then using the head "16" unscrewa bolt nut that tightens a ball pin with a steering knuckle. On the other hand, we hold the bolt with a wrench of the same diameter. We take out an element outside. Now we need to unclench the connection of the support pin and the knuckle. It’s not easy to do - you need a powerful minus screwdriver (you can use it to knock the bolt “16” if it is stuck in the slots). Then we deduce the ball from the hole of the knuckle. Be careful - the item may not give in. Therefore, at the same time shaking knuckle, holding the brake disc.

How is the ball bearing replaced atLada Largus with your own hands? In the next step, unscrew the nut of the rear bolt of the suspension arm. We will need a head with a ratchet "18", as well as an open-end wrench of the same size. Last we will keep the part from turning (as in the previous case). Then we get the bolt out. If it is tight, knock out with a slotted screwdriver. Now you can safely remove the lever out. But that is not all.

Remove the support from the lever

Now that the item has been removed from the car,proceed to disassemble it. Using a screwdriver, hook up the support under the shoulder. We press the ball out of the lever, resting on its edge. Next, we look at the state of the element itself. The hole in the lever should not have cracks and any gaps. If everything is in order, we clean it of dirt with a cloth dipped in gasoline or white spirit, and proceed to press in a new support.

To do this, we need to insert the part into the hole andPlace a pipe of suitable diameter under the lever. Light blows of the hammer press the element into the slots. Make sure that there is no skew. After that, the lever assembly with the ball can be installed in place. The assembly procedure is performed in a similar manner in reverse order.

Moments of puffs

When assembling it is important to properly tighten all the bolts.So, the nuts of fastening the silent blocks of the lever are tightened with a force of 105 Nm. Linkage - 21 Nm. The bolt that tightens the knuckle and ball, tightens with a force of 62 Nm.

note

After successful replacement of the ball, be sure to go through the procedure of adjusting the alignment.

The angles of the wheels after the repair may change, which will cause uneven wear of the rubber and drive the car to the side.

Repair parts or restoration?

Ball bearings can only be repaired.small workings. But doing it yourself is rather difficult. The cost of restoring ball bearings to the service station is about a thousand rubles. Plus removal and installation - 1400 rubles. Based on this, a better solution would be to purchase and install a new ball bearing on the “Lada Largus”.

The price of one item is 850 rubles (original from Renault). The cost of parts with a side groove (a kind of analog) - 620 rubles.

Conclusion

Ball bearing is a very important element indesigns of any car. Safety of driving depends on his condition without exaggeration. After all, a worn-out ball can simply jump out of the mountings, and the wheel will come off. At high speed, this can lead to serious consequences. Therefore, it is necessary not to ignore the problem and to diagnose the element at the first deaf impacts of the suspension. The wheel should not backlash when the car is on a lift or on a jack.
