WM, 4883IN Assessment Of Rear Axle Steering After Accident Damage: Information: Fundamentals

Various kinds of damage can occur to the servo motor for rear axle steering in the event of accidents or driving conditions similar to accidents. In cases where the servo motor shows no external damage, it can sometimes be difficult and costly to detect damage. Nevertheless, this damage represents an unacceptable risk for the vehicle because it could lead to failure of the rear axle steering.

A comprehensive check on all individual parts of the servo motor is not usually feasible due to the relatively high cost and is not possible using ordinary workshop resources. Instead, consideration must be given to the condition of other components that are easier to check.

To decide whether the rear axle steering of a vehicle involved in an accident must be replaced or may continue to be used, the following guidelines are helpful.
