Wheel alignment, mandatory sequence
of operations for checking


Overview of sequence of operations for
measuring wheel alignment

Vehicle must only be measured at curb
weight

Note:
Exception: when measuring the toe-in curve as
described in the alignment program instructions.

The following work sequences must be
adhered to

1 - Check front axle camber centering and
adjust if necessary page 44
-24
.

2 - Check rear axle camber and adjust if
necessary:

4 - If necessary, check toe-in curve on front
axle.

To determine if the toe-in curve or toe
constant "S" needs adjusting table on

.
The rear axle camber can be checked but not
adjusted on vehicles with front wheel drive.
If the readings are outside the allowable
tolerances the axle beam must be checked for
damage and replaced if necessary.

Rear axle toe (front-wheel-drive
vehicles), centering

Individual toe settings on the rear axle cannot be
adjusted.
By moving the rear axle within the elongated
holes it is possible to center the individual toe
settings.

- Loosen securing bolts on mounting brackets.

- Center individual toe settings by moving axle
beam within elongated holes at mounting
brackets.
If the overall toe setting is outside the allowable
tolerance, or if it is not possible to center the
individual settings, the axle beam must be
checked for damage and replaced if necessary.
The body alignment must also be
checked/measured in the area of the rear axle
mounting points and serviced as necessary.

Note:
The maximum adjustment range is 90 to the left or right of the center
position. - Loosen mounting nuts -1-.
- Adjust camber by turning eccentric bolt.- Tighten mounting nut, check camber again and if necessary re-adjust.

automatically alters the thrust angle of the axle.

- Adjust individual toe settings as necessary by turning eccentric bolt.
- Tighten mounting nut, check settings again and if necessary re-adjust.
