Use a pinion setting gauge in order to measure
differential drive pinion gear depth. The gauge provides
a normal or zero pinion as a gauging reference.
i. Install J 21777-40, J 21777-42, J 21777-43, and
J 21777-45.
2. Install J 23597-11.
3. Install J 21777-42 into the rear axle housing.
Notice: Refer to Fastener Notice in Cautions
and Notices.
4. Install the drive pinion gear setting gauge nut into
the rear axle housing.
Tighten .
Tighten the differential drive pinion· gear setting
gauge nut. to 2.3 N-m (20 lb in). ·
5. Rotate J 23597~ 11 ih order to seat the following
components: . . .
• The differential drive pinion gear outer
bearing (2) · ·
• The differential drive pinion gear inrier
bearing (1)
6. Mount J 8001 onto J 23597-1.
7. Preload the dial indicator against the plunger
about 1.27 mm (0.050 in).
8. Install J 21777-45 onto J 23597-11.
Position this unit into the rear axle housing.
9. Install the following components:
• The carrier bearing caps
(3)
"The bearing cap bolts/screws (2)
Tighten
Tighten the differential.carrier bearing cap
bolt/screws (2) to75N·m (551b.ft).
10. Use the following steps in order to measure the
differential drive pinion gear depth:
10.1. Rotate
J
23597-1 slowly back and forth
until J 8001 reads the greatest deflection.
The deflection is the point where the needle
changes direction.
10.2. At the point of deflection, set J 8001
to zero.
10.3. Repeat the rocking action in order to verify
the zero setting.
10.4. After obtaining the zero setting, rotate
J 23597-1 until the plunger no longer
touches J 23597-11.
This action provides the gauge reference of
a zero or nominal drive pinion gear.
