Checking axial run-out.
12. Place dial gauge to the crown wheel rear
side.
13.
Turn input flange and check Axial run-out
crown wheel max. 0.08 mm.
If the permitted axial run-out is not
obser
ved, check and correct contact of

14. Measure distance from the front face of the
AA02.060.628 [T
est device] to the front face
of the bearing inner ring. Measure distance of
each hole and calculate average.
Distance A = e. g. 59.44 mm

15. Remove AA02.060.628 [Test device].
16. Use AA01.266.870 [Load-lifting equipment]
to remove the differential from the axle
housing.
17. Check contact pattern
(See Check contact
pattern)
.
Correct deviations from the contact

ern.
If the shim for the contact pattern is
changed, proceed as follows:
