5 Assessing damage
5.1 General notes
When repairing vehicles which have been involved in an accident,
damage to the running gear or engine/gearbox mountings, etc. is
not always identified; in some cases this may result in serious
damage later on. If the accident damage indicates a high impact
load on the vehicle, special attention must be paid to the following
components (in addition to the wheel alignment check, which
must always be performed):
♦ Check to ensure that the steering assemblies and steering
linkage operate correctly over the complete lock-to lock range.
Carry out a visual check for bent or cracked parts.
♦ Check for distortion or cracking of running gear and all running
gear components such as links, suspension strut, wheel bear‐
ing housing, anti-roll bar, subframe and axle beam, as well as
associated fastening elements.
♦ Examine rims and tyres for damage, eccentricity and imbal‐
ance. Examine tyres for cuts/slits etc. in tread and sidewalls
and check inflation pressure.
♦ Examine the engine/gearbox/axle/exhaust system mountings
for damage.
♦ Finally, a thorough road test after completing repairs will give
the assurance that the vehicle is completely roadworthy and
ready for handing back to the customer.
5.2 Checking weld seams and aluminium
node castings
The dye penetration test is suitable for identifying surface cracks.
The approved repair materials must be used.
Note
Do not brush off the relevant area prior to testing, as this would
fill in the cracks.
