Assessment Of The Steering Of A Vehicle Involved In An Accident
The steering gear may remain in the vehicle if all the following conditions are met:
No visible damage to such front-axle parts as wheel rims, spring struts, wheel carriers, control arms, steering arms, tie rods, suspension sub-frame, the steering shaft or to the points on the body where wheel suspension parts are bolted on.
No impermissible rise in torque and no jamming or catching when the steering gear is turned from stop to stop. When the steering is turned, the front wheels must be free (front axle raised) and, in addition, the engine must be switched off (pump of power steering undriven).
The permissible tolerances for wheel alignment must not be exceeded.
The steering gear must be replaced by a new or exchange unit if one of the following points applies:
Visible or perceptible damage to the steering gear.
Fire damage (e.g. steering bellows burnt).
Permanent deformation or breakage of:
Steering-gear mountings
Tie rods
Steering arms
Spring struts
Wheel carriers
Control arms
Suspension sub-frame
If the listed criteria are insufficient for a decision, we recommend that the steering gear be replaced with a new or exchange unit.
