2.7 INSPECTION AND ADJUSTMENT, CASTER

Checking the caster
1.

Place the vehicle on a flat surface.

2.

Try to achieve a nominal axle load with the

trailing axle on the ground.

3.

Remove the prop shaft from the differential.

4.

Place an angle gauge on the drive flange and

measure the caster of the axle relative to the

chassis side member. See "Technical data"

for the specified caster.

Adjusting the caster, leaf-sprung trailing axle

Note:

The lowering of the lifting height of the trailing

axle reduces the caster. See "Technical data" for

the minimum lifting height of the trailing axle.

1.

Fit a block (B) (can be made by yourself)

under the stop block.

2.

Fit the stop block.

3.

If the correction made by this process is

insufficient, the caster must be corrected on

the driven axle.
