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".
