11. Remove the swivel axle from the axle end.

12. Disassemble the thrust bearing and grease 

the top side of bearing ring (3) (ribbed side 

with lubricating grooves).

13. Fit a new dust seal (1) to the thrust washer 

(2).

Make sure that the top of the dust seal is 

positioned under the top of the thrust 

washer.

14. Install the swivel axle with the correct shim 

on the axle end. See 'Removal and 

installation'.

15. Measure the play again.

Adjusting the swivel axle play, thrust bearing, 
assembled version
1.

Remove the swivel axle from the axle end. 

See 'Removal and installation'.

2.

Check the thrust bearing for wear or 

damage. If in doubt, replace the thrust 

bearing.

3.

Check the machined surfaces of the axle end 

and the swivel axle for damage.

4.

Fit the swivel axle with its original shim on the 

axle end.

5.

Fit the king pin. Hand tighten the nut.

6.

Place a jack under the swivel axle, pushing 

the thrust bearing against the axle end.

7.

Using a feeler gauge measure the gap 

between the shim and the swivel axle.

If necessary, use a shim with a different 

thickness until the specified axial play is 

achieved. See 'Technical data'.

Note:

The shim thickness can also be determined 

using the formula in the drawing.

8.

Remove the swivel axle from the axle end.

2.2 INSPECTION AND ADJUSTMENT, CASTER

General

-

The vehicle should be on a flat and horizontal 

surface, with the steering gear in the "straight 

ahead" position.

-

The caster can be measured using an angle 

measuring device or wheel alignment 

equipment.

Inspection of caster using angle measuring 
device
1.

Clean the spot where the angle measuring 

device is to be placed on the spring seat.

2.

Place the angle measuring device on a 

chassis side member and check whether the 

chassis is parallel with the floor.

If not, the caster reading should be adjusted 

to the chassis position.

3.

Place the angle measuring device on the 

spring seat and measure the angle.

Compare the reading with the specified 

value. See 'Technical data'.

4.

Carry out the caster measurement on the 

other axle side too.

If different readings are obtained, the front 

axle suspension should also be inspected for 

deviations.

Inspection of caster using wheel alignment 
equipment
1.

Use high-quality wheel alignment equipment 

for the inspection. The equipment must be 

calibrated regularly and preferably be of the 

type that can be calibrated before every use.

2.

Follow the instructions for the wheel 

alignment equipment carefully.

Adjusting the caster
1.

Fit a key of the required thickness between 

the spring seat and the spring. For the keys 

available, see 'Technical data'.

2.

Repeat the measurement once the key has 

been fitted.

2.3 INSPECTION OF CAMBER ANGLE AND KING PIN INCLINATION

Note:

In the following measurement, only the camber 

angle is measured. If the camber angle is correct, 

the king pin inclination must also be correct.

General

-

The vehicle should be on a flat and horizontal 

surface, with the steering gear in the "straight 

ahead" position.

-

The tyre pressure should be correct.

-

The camber angle can be measured using 

an angle measuring device or wheel 

alignment equipment.

-

The measurement should be carried out on 

both wheels.

Inspection of camber angle using angle 
measuring device
1.

Thoroughly clean the side of the wheel rim. 

Position the angle measuring device against 

the wheel rim. Keep the angle measuring 

device in the vertical position.

2.

Read off the angle shown. For the permitted 

angle, see 'Technical data'.

Inspection of camber angle using wheel 
alignment equipment
1.

Use high-quality wheel alignment equipment 

for the inspection. The equipment must be 

calibrated regularly and preferably be of the 

type that can be calibrated before every use.

2.

Follow the instructions for the wheel 

alignment equipment carefully.

For the permitted angle, see 'Technical data'.

The following points may cause the reading to 

deviate:

-

excessive swivel axle bearing play

-

bent front axle. In this case, the king pin 

inclination will also deviate from the values 

specified.
