8. Apply the park brake until a torque of
54-70
N-m
(40-52
lb ft) is required in order to turn
the drive pinion gear.
Important: A test made without loading .the gears will
not give a satisfactory pattern.
9. Use .the following procedure in order to obtain a
ring gear tooth contact pattern:
9.1. Turn the pinion gear yoke with a wrench so
that the ring gear rotates one full revolution.
9.2. Reverse the rotation so that the ring gear
rotates one revolution in the opposite
direction.
10. Inspect the differential ring gear teeth for a tooth
contact pattern (1 ). ·
11. The pattern is acceptable if the area of differential
drive pinion gear contact (1) remains in the center
of the differential ring gear tooth. If the pattern
is not acceptable, proceed to Step 14.
12. If the differential ring gear tooth pattern is
acceptable, remove J
39446.
13. Install the rear axle housing cover. Refer to
Rear (
Axle Housing Cover and Gasket Replacement.
14. Inspect the differential ring gear teeth for
a
low
flank contact pattern (2). -
15. If this contact pattern (2) exists, repair the low
flank contact by decreasing the shim thickness
of the bearing on the differential drive pinion gear.
This moves the smaller diameter of the
contact (2) out toward the center line (1) of the
differential ring gear.
