The steering rack of the VAZ-2109 rarely needs to be replaced, much more often it is necessary to carry out its adjustment. You can perform all the actions in a garage environment. The reasons for which adjustment is necessary are most often hidden in knocks arising in the steering gear. All front-wheel drive VAZ cars of the ninth and tenth generations use the same rack designs.
Very often, drivers confuse the sound of the steering rack with a similar sound that comes from the side of the ball bearings. But if after diagnosing the hinge you find out that it is in perfect order, you need to check the steering. Usually, when driving on flat roads, no sounds are heard. But as soon as a collision with a bump or hole occurs, a knock appears. This may be due to the fact that the mounting of the VAZ-2109 steering rack has loosened.
Major breakdowns
All the malfunctions that appear in the steering mechanism are due to the fact that the car very often drives on rough and dusty roads. If you are used to driving on broken roads slowly, trying to go around all the big bumps, then this will save not only the VAZ-2109 steering rack, but also all the most important suspension elements.
Very often, "young" drivers run into curbs, which leads to quick wear of steering elements. But nothing beats the torn boot. If water or dust gets inside the mechanism, then the entire assembly will have to be changed completely, since all rubbing parts will wear out very quickly. Symptoms of breakdowns:
- In the area of the steering mechanism, extraneous sounds are heard.
- Significantly increased steering wheel play.
- The steering wheel sometimes locks.
- Grease seeps through the boot on the mechanism.
You cannot operate a car with faulty steering, so you need to start repairing as soon as possible. Just be sure to make sure that it is the rail that is faulty, and not the ball bearing or racks. Otherwise, only in vain will you repair and spend a lot of money.
