9. Push the dial indicator downward until the needle
rotates about 3/4 turns.
10. Tighten the dial indicator in this position.
11. Set the button of J 36601 on the differential bear
ing bore (figure 22).
12. Rotate the tool slowly back and forth until the dial
indicator reads the lowest point of the bore. Set the
dial indicator to ZERO. Repeat the rocking action
of the tool to verify the ZERO setting.
13. After the ZERO setting is obtained and verified,
grasp the gaging arm by the flats and move the
tool button out of the differential side bearing bore
(figure 22). Record the dial indicator reading.
14. The dial indicator reading is equal to the required
shim size. Example: If the dial indicator reads
0.508 mm in step 8, a 0.508 shim is required.
Available shim sizes are listed in “ Specifications.”
NOTICE: Proper pinion depth setting is a
two-step procedure. Both procedures m ust
be performed to ensure proper axle perfor
mance and prevent system damage.
A. Setup dimension arrived at with the indica
tor is to be considered a starting point.
B. Gear tooth pattern check is necessary to
“fine-tune” the pinion depth and may indi
cate additional shim changes to the pinion
stem.
15. Remove the tool and bearing cones.

39. Bearinq Cup
F5868
Figure 21— Installing the Inner Pinion Bearing Cup
1. Shim (38) to the pinion gear (37).
• The shim must be of the proper size, as select
ed previously.
2. Bearing (39) onto the pinion gear using J 35512
(K1, 2 models) or J 36614 (K3 models) (figure 23).
3. New spacer (40) onto the pinion gear.
4. Bearing (41) into the case.
5. Seal (42) into the case using J 36366 (figure 24).
6. Pinion gear, with bearing and spacer, to the case.
7. Deflector (43), flange (44), washer (45), and nut
(46).
• Apply PST Sealant (GM P/N 1052080) or equiv
alent to the pinion gear threads and on both
sides of the washer.
• Tighten nut (46) until no end play is detectable
while holding the flange (44) with J 8614-01
(figure 11).
• No further tightening should be attempted until
the bearing preload has been checked.
t|Ji
Measure (Figure 25)
Pinion bearing preload. Use an inch-pound torque
wrench (figure 25). The correct preload is 1.7-2.8
N-m (15-25 lbs. in.).
1. Rotate the pinion with the torque wrench and
observe the reading.
2. If the preload torque is below specifications,
continue torquing the pinion nut in small incre
ments. Check the preload after each tightening.
Each tig h te n in g w ill increase the bearing
preload by several inch pounds. If the bearing
preload is exceeded, the pinion will have to be
re m o ve d , and a new c o lla p s ib le s p a c e r
installed.
3. Once the preload has been obtained, rotate the
pinion several times to make sure that the bear
ings have seated. Recheck the preload, and
adjust if necessary.
