Assembly and Installation<br />
If the differential has cotter pins or capscrews,<br />
lock the adjusting rings only with<br />
cotter pins or capscrews. If the differential<br />
has roll pins, reuse the roll pins. Do not<br />
force a roll pin into a cotter pin hole. Damage<br />
to components can result.<br />
7. Install the capscrews, cotter pins, roll pins<br />
or lock plates, if equipped, that hold the two<br />
bearing adjusting rings in position. Use the<br />
following procedures.<br />
A. Install capscrews between the lugs of the adjusting<br />
ring and through the boss of the bearing<br />
cap. New capscrews include a locking<br />
patch, which can only be used once. If you<br />
are installing used capscrews, apply Loctite®<br />
threadlocker to the capscrew threads<br />
before install the capscrews. Figure 5.59.<br />
B. Install cotter pins between the lugs of the<br />
adjusting ring and through the boss of the<br />
bearing cap. Bend the two ends of the cotter<br />
pin around the boss. Figure 5.59.<br />
C. Use a drift and hammer to install the roll pin<br />
through the boss of the bearing cap until the<br />
roll pin is between the lugs of the adjusting<br />
ring. Figure 5.59.<br />
D. Install the lock plate in the bearing cap so<br />
that the tab is between the lugs of the adjusting<br />
ring. Install the two capscrews and<br />
washers that hold the lock plate to the bearing<br />
cap. Tighten the capscrews to the correct<br />
torque value. See the Section 8. Figure 5.59.<br />

Adjusting Ring Gear Thrust Screw<br />
1. Rotate the differential assembly in the repair<br />
stand until the back surface of the ring gear is<br />
toward the DOWN.<br />
2.Install the jam nut in the thrust screw. Thread<br />
the jam nut to the middle of the thrust screw.<br />
Figure 5.60.<br />

3. Install the thrust screw in the ring gear. Use a<br />
feeler gauge to verify that the clearance between<br />
the thrust screw and the ring gear is<br />
0.025-0.045-inch (0.65-1.14 mm).<br />
4. Loosen the thrust screw one-half turn or 180<br />
degrees. Figure 5.61.<br />
