2.1 CHECKING THE DIFFERENTIAL OIL LEVEL

To prevent skin injury, avoid 

unnecessary contact with the 

drained oil.

1.

Position the vehicle on a level surface.

2.

Lower the trailing axle, if present, on a leaf-

sprung version.

3.

Remove the oil-level check/filler plug (A). 

The oil level should reach the level check/

filler opening.

4.

Fit the plug using the special tool 

(DAF no. 1329493) and tighten the plug to 

the specified tightening torque. See

2.2 CHECKING THE OPERATION OF THE DIFFERENTIAL LOCK

1.

Jack up the rear axle and support the axle on 

stands.

2.

Bring the air system to operating pressure.

3.

Engage the differential lock. The warning 

lamp should now come on.

4.

Check that there is a "rigid" connection 

between the driven wheels.

5.

Disengage the differential lock. The warning 

lamp should not light up and the "rigid" 

connection between the driven wheels 

should be broken.

2.3 CHECKING THE WHEEL SPEED SENSOR RING

1.

Remove the wheel hub unit.

2.

Check the sensor ring (2) for deposits. 

Special attention should be paid to deposits 

between the teeth of the sensor ring.

Clean the sensor ring if necessary.

3.

Check the sensor ring (2) for damage. Even 

the slightest damage can cause a failure.

If necessary replace the sensor ring.

4.

If possible, the sensor ring (2) should be 

checked for the maximum admissible axial 

end play. See "Technical data".

5.

Check the sensor (1) for freedom of 

movement.

If necessary, clean the sensor (1) and apply 

new grease.

4.

Remove the axle shaft using special tool 

(DAF no. 0694980), if required, see (B).
