Wheel alignment
2.1
Notes for wheel alignment
Wheel alignment may only be performed using wheel alignment
units approved by the Workshop Equipment department.
All of the information about wheel alignment can be gleaned
from the wheel alignment computer.
Vehicles pulling to one side and accident vehicles:
This may be due to the rack in the steering rack not being
exactly centred when vehicle is driven straight ahead.
Power steering assistance is thereby slightly one sided, rather
than central.
The vehicle will pull to one side as a consequence.
2.2
Prerequisites for wheel alignment
Important
•
Wheel alignment platforms and wheel alignment units must
be checked and adjusted as necessary during inspection
and maintenance at least once per year.
•
•
Check wheel suspension, wheel bearing assembly and
steering for excessive play and damage.
Tread depth difference on the same axle must not exceed
2 mm.
•
•
•
Tyres inflated to correct pressures.
Vehicle unladen.
Vehicle tool kit must be stowed in correct location.
Please note the following:
Important
•
Ensure that none of the sliding plates and turntables are at
the end stop during the measurement.
•
The test equipment must be properly adjusted and attached
to the vehicle; observe device manufacturer's operating in‐
structions.
If necessary, ask the manufacturer to show you how to use the
wheel alignment machine.
– Handle these highly sensitive devices carefully and consci‐
entiously.

– Front axle: balance out ride height by adding weights to
respective suspension turret.
– Rear axle: balance out ride height by placing weights in
luggage compartment at respective side.
2.5

Wheel alignment is necessary if:
♦ The vehicle does not handle properly.
♦ Vehicle has been involved in an accident or components
