Inspection of axial steering ball joint play
1.

Check the axial steering ball joint play using

special tool (DAF no. 1329426).

2.

First jack up the axle until the wheels come

off the ground and put the axle on stands.

3.

Make sure that the castle nut split pin (if

fitted) at the nut does not come into contact

with the head of the threaded end.

4.

Screw the thrust washer (8) onto the

threaded spindle.

5.

Fit the spring retainer (3), spring (4) and

pressure sleeve (6) into bracket (1).

Fit the locking screw (5). It should be

possible to move the pressure sleeve (6)

freely.

Note:

Fit the correct pressure sleeve (6).

The pressure sleeve (6) must abut the outer

edge of the steering ball joint (7).

6.

Loosen thrust bolt (2) until the flange of the

pressure sleeve (6) abuts the bracket (A=0

mm).

7.

Fit the special tool over the steering ball

joint (7) and turn the threaded spindle (9) by

hand until the special tool is tight around the

steering ball joint (7).

8.

Tighten thrust bolt (2) until its head abuts

bracket (1).

9.

Measure play "A" between the pressure

sleeve and the bracket using a feeler gauge.

Compare the reading with the maximum

permissible steering ball joint play, see

'Technical data'.

If necessary, replace the steering ball joint.

2.7 INSPECTION OF AXLE HOUSING

General
When the vehicle has been involved in a collision

or when abnormal deviations are measured

during the inspection of the wheel alignment, it

may be wise to inspect the axle housing.

A number of the following measurements can

also be carried out using alignment equipment.

Consult the alignment equipment manual for this.

The special tools required cannot be obtained

from DAF and should be manufactured by

yourself.

Inspection of axle housing
1.

Remove the vehicle's axle and both swivel

axles. See 'Removal and installation'.

2.

Place a straight edge over the spring seats of

the axle housing and check whether they are

aligned.

3.

Place a straight edge over both spring seats

and check whether they are parallel with

each other.

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.

2.8 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.
