Chassis Alignment
The following points must be noted before chassis alignment:
- Use of the specified disc wheels as well as the tyre
sizes.
- Perfect condition of the disc wheels and the wheel bearing
units.
- Tyre tread uniform and in good condition.
- Correct tyre inflation pressure on each axle, left and right
identical - values see the respective Owner's Manual for the
vehicle or the "Inspection System" or "Inspection System/Service
Plan" brochure applicable to the model year.
- No visible damage to chassis (no play in track rods and ball
joints, chassis suspension).
- Regulations and instructions issued by chassis alignment system
manufacturer.
The following operations must be performed before chassis
alignment:
- Half fill fuel tank.
- Put vehicle into alignment position.
- Load both front seats with 70 kg.
- Put steering in straight ahead position.
- Push down on vehicle suspension several times to enable the
suspension to adopt its starting position.
Measure
Using the computer-aided chassis alignment system, establish
"actual values", see "Technical Data - Chassis Adjustment Values"
in group "E" and/or from MY '99 in the respective "Chassis
Adjustment Values" brochure valid for the model year for the
"required values". The instructions for users and stipulations of
the manufacturers of computer-aided chassis alignment systems must
be observed. Print-out of the vehicle and chassis data.
Note: Since
semi-independent suspension is used on this vehicle, it is not
possible to adjust the position of the rear axle. If the "actual
values" do not correspond to the "required values", the fixing
points of the rear axle on the underbody of the vehicle must be
checked and corrected if necessary - see operation "Quick measuring
method" in group "A".
If the fastening points of the rear axle on the vehicle
underbody are correct, a precise alignment of the rear axle should
be undertaken with KM-6002. The alignment of the rear axle is
described in the operation "Rear Axle, Remove and Install". After
aligning the rear axle, the vehicle must be realigned.
If, despite correct alignment of the rear axle, the "actual
values" do not correspond to the "required values", the rear axle
must be replaced.
