Replacing the steering in case of accident damage
A. General
Accidents or driving conditions similar to accidents may cause various types of damage to steer-
ing gears. if the outside of the steering gear is undamaged, tracing of damage is sometimes
difficult and requires considerable effort. This, however, constitutes an incalculable risk for the safety
of the vehicle as it may lead to steering failure.
Due to the fact that a comprehensive check of all steering gear components requires considerable
effort and is therefore not normally justifiable or even impossible to be carried out with standard
shop equipment, the condition of other components that are easier to be checked must be con-
sidered as a replacement solution.
The following guidelines (item B) should be observed to decide if the steering gear of an accident ve-
hicle requires replacement or may be used as t is.
8. Assessing the Condition of the Steering System of an Accident Vehicle
The steering gear may remain on the car if all the followlng conditions are met:
- No visible damage to front-axle components such as wheels, king pins, control arms, steering
arms, tie rods, to frontaxle crossmember, steering shaft, as well as to the suspension mountings
at the body.
- No inadmissible increase of torque and no binding or stiffness when the steering gear is turned
from lock lo lock. When moving the steering form lock to lock, the front wheels must be off the
ground (front axle raised) and the engine must be stopped (no drive to power steering pump).
- Admissible suspension alignment tolerances must not be exceeded.
The steering box muat be replaced or exchanged if any of the following points apply:
.
Damage to steering gear Is visible or can be felt
.
Burning damage (e.g. bellows of steering burnt)
