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.
