The deformation and bending of the rear axle of the automobile not only concentrate the load on the inner shoulder of the inner tire, but also reduce the landing area of the tire, increase the pressure per unit area and accelerate the wear of the inner tire. At the same time, the car will shake from side to side when driving, resulting in jagged or irregular wear on the shoulder.

The main reasons for the deformation of the rear axle are as follows:

1, the vehicle load is too large, and the rear axle house is overloaded, resulting in the deformation of the rear axle house.

2. Driving at high speed in the case of poor road conditions or uneven road surface.

3. The rear axle sleeve is loose or displaced.

4. Improper adjustment of the left and right wheel bearings of the rear axle leads to loose locking nuts or slipping teeth.

As long as we pay attention to the above four points in the daily use and maintenance of vehicles, we can avoid the deformation of the rear axle to the greatest extent.
