4.

Place the two gauge bars in the swivel axle

holes.

Place a straight edge with a protractor on the

spring seat. Measure the angle of the gauge

bars in relation to the spring seats. The angle

measured should be 90

.

5.

Measure the king pin inclination (KPI) by

placing a straight edge with a protractor on

the spring seats.

By placing the straight edge of the ruler

parallel with the gauge bar, the angle can be

read.

6.

If a deviation is found during one of the

inspections, the axle housing should be

replaced.

The axle housing should not be

straightened. This could affect the

material strength.

2.11 INSPECTION OF WHEEL RIM

General
1.

Inspect the wheel rims for the following

points:

-

deformation of the wheel rims, wheel

disc and/or Trilex parts. In the case of

twin wheels, also inspect the inside

wheel.

-

deformation or cracking of the wheel

stud holes.

-

corrosion, including at the tyre side of

the rim and on the rim ring.

2.

Cracked or damaged wheel rims or wheel

rims with cracked or deformed wheel stub

holes should be replaced.

It is prohibited to weld wheel rims or repair

these in some other way. After some time,

the weld will crack again due to the dynamic

load.

When removing such a damaged

wheel rim from the vehicle, deflate

the tyre (remove the tyre valve) in

view of possible tensions in the

wheel rim.

3.

To prevent damage to the tyre due to

corrosion and/or indirect tension cracks (due

to notching), the anti-corrosion treatment of

the wheel rim should stay fully intact.

For the removal of corrosion and repair of the

paint layer, see 'Paint treatment'.

Before re-spraying, remove the old paint

layer to prevent the total paint layer from

becoming too thick. The total paint layer

thickness should not exceed 50 microns.

At a total paint layer thickness (wash

primer and finishing paint) of more

than 50 microns, the pre-tension of

the wheel studs might be reduced if

this layer were to be crushed. This

could result in the wheel nuts

coming loose.

2.12 INSPECTION OF WHEEL SPEED SENSOR RING

1.

Remove the wheel hub unit. See 'Removal

and installation'.

2.

Check the sensor ring (1) for deposits.

Special attention should be paid to deposits

between the sensor ring teeth

Clean the sensor ring if necessary.

3.

Check the sensor ring (1) for damage. Even

the tiniest damage may cause a failure.

Replace the sensor ring if necessary, see

chapter 'Removal and installation'.

4.

If possible, the sensor ring (1) should be

checked for the maximum admissible axial

end play. See 'Technical data'.

5.

Check the sensor (2) for freedom of

movement.

If the sensor cannot move freely, remove,

clean and refit it. See chapter 'Removal and

installation'.

Never tap the sensor into the swivel

axle using a hammer. This may

damage both the sensor and the

sensor ring.

6.

Check the operation of the EBS or ABS

system.
