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.

driven axle is free.

Note:

Ensure that both the chassis and axle are 

well supported with stands.

2.

Loosen the U-bolt nuts so that the correct 

key can be fitted to position (A).

3.

Tighten the U-bolt nuts evenly on both sides 

to the specified torque.

4.

Check the caster again.
