11.1.11. Diagnostics of malfunctions of a suspension bracket and steering

Before starting checks of components of a suspension bracket and a steering drive make sure that a cause of infringement is not the wrong rating of tires, installation of tires of a various standard size or "prikhvatyvaniye" of brakes. Also check a condition of kardanny hinges of a steering column, reliability of fastening of components of a suspension bracket and the steering mechanism, and a condition of wheel bearings.


Symptom Possible reason
Course stability of the car is broken Tires of a various standard size are established, or protectors (are non-uniformly worn-out see. Head Steering).
Springs (are broken or gave see. Head Steering).
Adjustment of corners of installation of lobbies or back wheels of the car (by cm Head the Steering) is broken. Brake mechanisms of forward wheels (are faulty see. Head Brake system).
Abnormal or excessive wear of tires takes place Adjustment of corners of installation of lobbies or back wheels of the car (is broken see. Head Steering).
