(14) Tighten the pinion nut until there is zero
bearing end-play (Fig. 30).
(15) Tighten the nut to 271 N·m (200 ft. lbs.).
CAUTION: Never loosen pinion nut to decrease pin-
ion bearing rotating torque and never exceed spec-
ified preload torque. If preload torque or rotating
torque is exceeded a new collapsible spacer must
be installed. The torque sequence will then have to
be repeated.
(16) Using Holder 6719 and a torque wrench set at
474 N·m (350 ft. lbs.), crush collapsible spacer until
bearing end play is taken up.
NOTE: If the spacer requires more than 474 N·m
(350 ft. lbs.) torque to crush, the collapsible spacer
is defective and must be replaced.

(17) Slowly tighten the nut in 6.8 N·m (5 ft. lbs.)
increments until the desired rotating torque is
achieved. Measure the rotating torque frequently to
avoid overcrushing the collapsible spacer (Fig. 31).
(18) Check bearing rotating torque with an inch
pound torque wrench (Fig. 31). The torque necessary
to rotate the pinion should be:
• Original Bearings — 1 to 2.5 N·m (10 to 20 in.
lbs.).
• New Bearings — 1.7 to 2.5 N·m (15 to 22 in.
lbs.).
(19) Install the differential in the axle housing.
