bearing end play is taken up (Fig. 63). If more than
353 N·m (260 ft. lbs.) is needed to begin to collapse
the spacer, the spacer is defective and must be
replaced.
(10) Slowly tighten the nut in 6.8 N·m (5 ft. lb.)
increments until the rotating torque is achieved.
Measure the rotating torque frequently to avoid over
crushing the collapsible spacer (Fig. 64).
(11) Check bearing rotating torque with an inch
pound torque wrench (Fig. 64). The torque necessary
to rotate the pinion should be:
•
Original Bearings — 1 to 2 N·m (10 to 20 in.
lbs.).
•
New Bearings — 1.5 to 4 N·m (15 to 35 in. lbs.).
(12) Install differential assembly.
RING GEAR
NOTE: The ring gear and pinion are serviced as a
matched set. Do not replace the ring gear without
replacing the pinion.
REMOVAL
(1) Remove differential from axle housing.
(2) Place differential case in a suitable vise with
soft metal jaw protectors. (Fig. 65)
(3) Remove bolts holding ring gear to differential
case.
(4) Using a soft hammer, drive ring gear from dif-
ferential case (Fig. 65).
INSTALLATION
CAUTION: Do not reuse the bolts that held the ring
gear to the differential case. The bolts can fracture
causing extensive damage.
