1

 Place spreader (01) on rear axle housing and tighten.

2

Insert differential with appropriately calculated shims into rear axle housing.

 Install the thinner shim on the ring gear side (arrow) so that the gear backlash is achieved in each case.

3

 Loosen and remove spreader (01).

4

Insert bearing bracket (16) and tighten bolts by hand.

 Observe the markings made on the bearing brackets (16) to indicate the original installation position.

5

Check gear backlash with  dial indicator holder and  dial indicator.

 The gear backlash can be adjusted by installing shims. If a thinner shim is installed on one side, a shim which is thicker by the same amount must be installed on the opposite side so that the preload of the differential housing bearing is retained.

6

Compare measured play with specified value and install different shims if necessary.

7

Tighten mounting bolts of bearing brackets (16).
