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.
