Ball joints are the most short-lived suspension parts of the AvtoVAZ classic. Given the state of domestic roads, the ball joint on the VAZ 2107 is the first part that has to be changed after a certain run of the car. Novice motorists have questions about how to replace ball joints and which ball is better to put on the VAZ 2107.

The design of the front suspension with ball bearings has replaced the previously popular pivot mechanism and is the most common. The task of these nodes is to provide vertical movement and rotation of the wheel while driving. Ball joints are constantly exposed to strong alternating loads while the vehicle is in motion, and their breakage is fraught with a serious accident. Therefore, special requirements are imposed on the material and quality of production of ball joints. The rapid wear of the ball bearings during operation even forced the designers to develop suspension options without this "delicate" unit. But, as mentioned above, most cars (and the VAZ line of cars completely) include ball joints in the front suspension design.

"Ball" (as abbreviated as they are called) are made in two versions: jellied structures and products with a cermet insert. The first type is used in the upper, the second - in the lower ball joints. This is due to the different loads that the liners are subjected to. In the lower nodes, compression and tension occur alternately, in the upper ones, only compression.

On the Russian market, more than 30 companies offer ball on VAZ 2107... Of these, products of such brands are especially popular:

These brands, according to reviews of car service specialists and the results of a customer survey, do not cause any complaints in terms of quality and are in greatest demand. Units from other companies occupy no more than 5% of the market for this type of spare parts.

The reliability of the ball joints is extremely important for safety, therefore, their condition must be carefully monitored and replaced at the first sign of malfunction, which manifests itself in the following:

  • knocking while driving at low speed;
  • squeak when turning the steering wheel, emanating from the area of ​​\ u200b \ u200bthe attachment of the wheels;
  • unstable holding of the course;
  • uneven tire wear;

[warning] The lifespan of the ball joints depends on the driving style and the condition of the road surface. Given the important role of components, ball joints must be inspected before long journeys, not limited to regular maintenance.

At the slightest sign of wear, the ball must be replaced, as a worn ball can fly out a finger, as a result of which the wheel will turn out and the car will unpredictably change its trajectory. [/ Warning]

The replacement of the ball joints can be carried out independently without the involvement of car service mechanics.

It is better to replace the ball valves by lifting the car on a lift or placing it in an inspection pit. This will provide easy access to parts and a good overview. But you can do without it.

You will need the following tools:

  • a set of keys;
  • adjustable wrench;
  • puller for ball;
  • hammer;
  • drift;
  • solvent or liquid WD-40;
  • medical syringe;
  • grease.

Replacing ball joints does not require unique skills and is available to anyone who knows how to handle a wrench. Before starting work, it is necessary to hang the car on a lift or turn on the "handbrake" and put on the wheel chocks.

  1. Loosen the wheel bolts.
  2. Jack up the vehicle by hanging the wheels (or lifting on a lift).
  3. Unscrew the wheel bolts and remove the wheel.
  4. Clean the threads on the pins and bolts of the ball joints with a wire brush.
  5. Treat threaded connections with solvent or WD-40 to facilitate loosening.
  6. Using a 22 wrench, loosen the nuts on the pins of the upper and lower supports.
  7. Install the puller according to the instructions.
  8. Press out the supports (if you do not learn, you need to "help" with a hammer and a punch).
  9. Unscrew the nuts on the ball pins and remove the pins from the front wheel mechanism knuckle.
  10. Unscrew the nuts and remove the bolts securing the support to the lever.Image - DIY repair of ball joints VAZ 2107
  11. Remove the ball joints.

Installation of ball joints occurs in the reverse order of removal. Before installing in the ball (under the boot), you need to put grease. Special attention should be paid to the tightening torque of the ball nuts and the integrity of the anthers of the ball joints. If the boot is torn, dirt will get between the pin and the ball joint liner and the bearings will fail very quickly.

Now you know what ball joints on the VAZ 2107 are for, which ones are better to buy and how to independently replace worn-out ball joints with new ones.
