Notes
^
Tapered roller bearings for differential are low friction bearings. Therefore friction torque can only be used for check measurement in a limited
way. A correct adjustment is only possible by determining the total thickness "Stotal".
^
Do not grease new tapered roller bearings additionally for Action torque measurement. The bearings are already greased with a special oil from the
factory.
Total shim thickness "Stotal" for adjustment shims "S1" + "S2", determining
(adjust preload of tapered roller bearing for differential)
Drive pinion removed or ring gear detached from differential housing
-
Pry out drive flange seal using tire iron.
-
Remove tapered roller bearings for differential and remove adjustment shims-, Refer to Differential Assembly, Service and Repair
-
Press tapered roller bearing outer race for left side of differential housing (housing side) together with shim "S2" into differential housing, Refer to
Differential Assembly, Service and Repair. Use a shim "S2*" with a 1.00 mm thickness for measurement purposes (1 shims with 0.80 and 1 with
0.20 mm).
Note: All measurements are performed shim S2 with 1.00 mm thickness. The shim will be indicated by "S2*" in the following procedures. After
determining backlash, S2*"is replaced by final shim S2.
-
Press in tapered roller bearing outer race for right side (cover side) of differential without adjustment shims to stop, Refer to Differential Assembly
, Service and Repair, See Fig. 8.
-
Insert differential in housing. Ring gear is on the right side (cover side).
-
Install cover and tighten bolts to 25 Nm.
-
Install VW521/4 locking sleeve and 521/8 sleeve press tool into differential housing on housing side.
-
Rotate cover side of differential housing upward.
-
Turn differential 5 rotations in each direction to seat the tapered roller bearing.
-
Place VW385/17 magnetic plate onto differential.
