Diagnosing vehicles damaged in an accident
When repairing vehicles damaged in an acci- dent, it is sometimes the case that damage to the chassis or components suspension is not discovered and this may subsequently result in severe consequential damage. When inspecting vehicles which have been damaged in an acci- dent where it is suspected that considerable stresses were involved, it is therefore necessary to pay particular attention to the following com- ponents - irrespective of the check of the chassis alignment which should always be carried out as well:
If it is suspected that the floor assembly has been damaged and/or twisted, the vehicle has to be inspected on the frame straighten-
ing rig and straightened, if necessary.
Inspect the steering and steering linkage to ensure that they operate properly over the entire movement. Carry out a visual inspec- tion for twisting or cracks.
Inspect all components of the running gear such as steering arms, suspension struts, steering knuckles, anti-roll bars, subframe, axle beams and the attachment points of such parts for twisting or cracks.
Examine wheels, tyres for signs of damage, concentricity and imbalance. Examine the tyres for cuts to the tread and the side walls. Check the tyre inflation pressure.
Examine the suspension of the engine, gear- box, axles and exhaust system for signs of damage.
The final step is a reasonable road test after carrying out repairs as an assurance that the vehicle is safe for the road and can be han- ded over to the customer without hesitation.
