3.1 Checklist for evaluating running gear of
accident vehicles
Damage to running gear may go unnoticed during repairs to load-
bearing and suspension parts of accident vehicles. Under certain
circumstances, this undiscovered damage could lead to serious
consequential damage during later vehicle operation. Therefore,
the following parts of accident vehicles must be examined in the
manner and order described independent of wheel alignment
which may have to be performed. If no deviations from specifica‐
tions are measured during wheel alignment, there are no defor‐
mations of the running gear.
Visual and functional check for the steering system.
♦ Visual examination for cracks and deformation.
♦ Examination for play in track rod joints and steering box
♦ Visual examination for tears in boots
♦ Examination of electrical wiring and hydraulic lines and hoses
for chafing, cuts and kinks.
♦ Check hydraulic lines, threaded connections and steering box
for leaks.
♦ Check steering box and lines for secure seating
♦ Check for flawless function from lock to lock by moving the
steering from stop to stop. In the process, the steering wheel
must turn with a constant force without resistance.
Visual inspection and functional check of the running gear.
• Adhere to the sequence of the following inspection steps!
♦ Check all components shown in the assembly overviews for
deformation, cracks and other damage
♦ Renew damaged parts.
♦ Align the vehicle axles using a wheel alignment unit authorised
by SEAT.
Visual and functional check of wheels and tyres
♦ Check for true running and imbalance.
♦ Check tyres for cuts and impact damage in tread and on flanks.
⇒ page 311
♦ Check tyre inflation pressure; information on mandatory tyre
inflation pressure can be found on a sticker attached to B-pillar
on driver side or to inside of tank flap.
If rim of wheel and/or tyre is damaged, renew tyre. This also ap‐
plies if the circumstances of the accident and the damage to the
vehicle indicate possible damage which is not visible.
A further factor in the decision is the age of the tyre. Tyres should
not be older than 6 years.
If in doubt, the following always applies:
• Whenever a safety risk cannot be excluded, the tyre(s) must
be renewed.
