Test Values For Friction Torque Of Rear Axle Differential:

Special Tools:

Component Identification:

1 Attach spreader (058) to the rear axle housing; to do this, tighten collar bolts (arrows) (guidance value: approx. 50 Nm).

Component Identification:

2 Position measuring yoke (059) for expansion dimension measurement on spreader (058) and press against the two bolts from below. Set dial gauge to "0" with 3 mm preload.

The stop pin (arrow) on the contact arm must touch the contact surface on the rear axle housing.

Component Identification:

3 Turn the even surface (arrow) of the thrust piece to the opening of the locking ring (29).
4 Screw in the threaded spindle (058a) of the spreader (058) by hand until the thrust piece abuts the tapered roller bearing outer race.

Component Identification:

5 Screw in the threaded spindle (058a) of the spreader (058) until the rear axle housing has reached a spread dimension of 0.10 to 0.13 mm. Do not exceed the spread dimension when spreading. Otherwise the rear axle housing may become damaged.
6 Remove contact arm (059).

Component Identification:

7 Remove left circlip (29) from rear axle housing using pliers (064)
8 Mark the left circlip (29).
9 Unclamp the rear axle housing and detach spreader (058).
