3.9 REMOVAL AND INSTALLATION, TANDEM AXLE SPRING ASSEMBLY

Support the vehicle securely and 

work safely.

Removing tandem axle spring assembly
1.

Support both axles and remove the wheels.

2.

Jack up the chassis under the central 

suspension.

3.

Loosen the nuts (1) of the tie rods (4) until the 

centre bolt comes off the pivot pin shackle.

4.

Lower the chassis until the spring assembly 

rests on wearing plates (2).

5.

Remove the tie rods (4) and the bottom 

spring plate (3). The spring assembly is now 

ready to be taken off.

Before the spring assembly of a 

trapezoidal leaf spring assembly is 

taken off, it must be turned upside-

down. If this is not done, the spring 

assembly will tip over when being 

removed.

6.

Turn the spring assembly of a trapezoidal 

leaf spring assembly upside-down. Remove 

the spring assembly.

Installing tandem axle spring assembly
1.

Put the spring assembly on the brake drums. 

Turn the spring assembly of a trapezoidal 

leaf spring assembly right side up again, so 

that the short side is on top.

2.

Put the spring assembly side by side on the 

wearing plates. This will prevent the 

trapezoidal leaf spring assembly from tipping 

over.

3.

Fit the tie rods (4) and the spring plate (3).

When tightening, check that the centre bolt 

head is located in the recess of the bearing 

support and that the alignment plates fit onto 

the cams of the bearing support.

4.

Lower the chassis.

5.

Tighten the tie rods (4) to the specified 

torque. See "Technical data".

Make sure that the attachment nuts fully 

engage the tie rod.

6.

Apply grease to the threaded ends of the tie 

rods sticking out above the attachment nuts.

7.

Put the wheels back on.

8.

Re-torque the tie rod nuts after 2,500 km.
