Correcting the misalignment of air-sprung 
axle(s) and tandem axle suspension
-

The misalignment of the axle can be 

corrected by fitting a hardened steel ring 

(DAF no. 0202838) between the torque rod 

and the torque rod bracket. This ring is 3 mm 

thick. Grind the ring, if necessary. The 

application of more than one ring is not 

acceptable. The application of more than 

one ring would increase the risk of a 

loosening connection.

-

The thickness of this shim in mm should be 

equal to the rear axle misalignment in mm/m.

Correcting the misalignment of a leaf-sprung 
trailing axle suspension
The driven axle can be repositioned to correct a 

misalignment (non-parallelism) between the 

driven axle and the trailing axle.

The alignment of the driven axle is determined by 

a metal block (A), which is placed in a recess of 

the axle seat.

This block contains a hole for the spring 

assembly centre bolt. Replacing this block with a 

block with the hole further to the front or the rear 

will cause the entire axle to shift forward or 

backward at that side.

For this purpose blocks (B) without a hole can be 

ordered, (DAF no. 0893145). 

The hole must be custom drilled in the correct 

position.

1.

Have a block without a hole at hand.

2.

Determine the misalignment of the driven 

axle relative to the trailing axle in mm/m.

3.

The misalignment value is the distance 

between the centre of the hole to be drilled 

and the centre of the block (distance L in the 

adjacent drawing).

4.

Very accurately drill a 

 17.5 mm hole in the 

block in the correct place. Check the 

distance.

5.

Remove the nuts from the U-bolts.

6.

Jack up the chassis until there is sufficient 

clearance between the spring assembly and 

the axle seat. Support the chassis in a safe 

way.

7.

Remove the metal block which is now loose 

in the axle seat.

8.

Place the new block in the axle seat, making 

sure that the position of the axle is adjusted 

in the right direction.

9.

Install the U-bolt nuts and tighten them to the 

specified tightening torque, see "Technical 

data".

Correcting the misalignment of a leaf-sprung 
axle suspension
A leaf-sprung suspension can only be corrected 

to a very limited degree.

The only possible correction is using the available 

play between the spring bracket and the chassis.

1.

Loosen the spring bracket attachment bolts 

and slide the spring bracket as far as 

possible in the desired direction.

2.

If this is insufficient, the spring bracket on the 

opposite side of the chassis can be moved in 

the opposite direction.

3.

Make sure that the contact surfaces between 

spring bracket/chassis are absolutely free 

from paint, grease and dirt. Tighten the 

spring bracket attachment bolts to the 

specified torque. See "Technical data".
