7.

Install the guide sleeve (A), which is part of 

the special tool set (DAF no. 1329496), on 

the axle journal.

8.

Remove the wheel hub unit (6) using a lifting 

device. Take care that the wheel hub unit 

does not rest on the guide bush (A) as the 

latter is not strong enough to take the weight 

of the wheel hub unit.

Installation of wheel hub unit
1.

Check the wheel hub speed sensor ring, see 

'Technical data'.

2.

Check the axle journal thread carefully for 

damage.

You must never fit a wheel hub unit 

on an axle journal with a damaged 

thread.

3.

Apply a thin and even layer of the prescribed 

anti-corrosion agent to the entire 

circumference of the axle journal, see 

'Technical data'.

Note:

Do not apply too much anti-corrosion agent 

to the axle journal. While fitting the wheel hub 

unit, the excess anti-corrosion agent will 

collect at the backside of the wheel hub. 

When the vehicle is used in daily operation, 

this can leak out so that the seal wrongly 

appears to be leaking.

4.

Install the guide sleeve (A), which is part of 

the special tool set (DAF no. 1329496), on 

the axle journal.

Check that the spring clip, located between 

the inner bearing races, is positioned

Position the wheel hub unit (6) precisely in 

front of the axle journal using a lifting device. 

Slide the wheel hub unit (6) onto the axle 

journal without twisting it. Take care that the 

wheel hub unit does not rest on the guide 

bush as the latter is not strong enough to 

take the weight of the wheel hub unit.

7.

Fit the thrust washer (5).

8.

Replace the hub nut (4). Apply a few drops of 

oil to the abutting surface of the hub nut. Fit 

the hub nut.

9.

Fit the hub nut (4) using the special tool set 

(DAF no. 1329496).

Fit the socket wrench (A) to the hub nut. Fit 

the socket wrench guide (B) to the wheel hub 

unit using four nuts. Tighten the hub nut (4) 

in the specified manner using a torque 

amplifier, see 'Technical data'.

10. Fit a new O-ring (3) to the hub cap (2).

13. Press the wheel speed sensor (2) against 

the sensor ring (1) by hand. While the vehicle 

is being driven, the air gap between the 

sensor and the sensor ring is adjusted.

remove, clean and refit it.

Never tap the sensor with a hammer. 

This may damage both the sensor 

and the sensor ring.

14. Check the operation of the EBS or ABS 

system.
