4.

Apply a thin and even layer of the prescribed

lubricant to the axle journal, see "Technical

data".

Note:

Do not overlubricate the axle journal. While

fitting the wheel hub unit, the excess grease

will collect at the backside of the wheel hub.

When the vehicle is used in daily operation,

this anti-corrosion agent can leak out so that

it looks as if the oil seal leaks.

5.

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

the axle journal.

6.

Attach the wheel hub unit (3) securely to a

movable lifting device.

7.

Position the wheel hub unit (3) exactly in

front of the axle journal using the movable

lifting device. Slide the wheel hub unit (3) on

the axle journal.

Take care that the wheel hub unit (3) does

not rest on the guide bush as the latter is not

strong enough to take the weight of the

wheel hub unit (3).

8.

Fit the thrust washer (2).

9.

oil to the abutting surface of the hub nut (1).
