Place the proper thickness pinion depth shim
on the pinion gear.
(5) I n s t a l l the rear bearing (and slinger i f used) on
the pinion gear w i t h Installer 6448 (Fig. 29).

(6) I n s t a l l a new collapsible preload spacer on pin-
ion shaft (Fig. 30).
(7) I n s t a l l pinion gear i n housing.

(8) I n s t a l l yoke w i t h Installer C-3718 and holder
6958.
(9) I n s t a l l the yoke washer and a new n u t on the
pinion gear. Tighten the n u t to 298 N - m (220 ft. lbs.)
m i n i m u m . D o not over-tighten. M a x i m u m torque is
380 N - m (280 ft. lbs.).

(10) Using yoke holder 6958, a short length of 1 i n .
pipe, and a torque wrench set at 380 N - m (280 ft.
lbs.), crush collapsible spacer u n t i l bearing end play
is taken up.
(11) Slowly tighten the n u t i n 6.8 N - m (5 ft. lbs.)
increments u n t i l the r o t a t i n g torque is achieved.
Measure the r o t a t i n g torque frequently to avoid over
crushing the collapsible spacer (Fig. 31).
(12) Check bearing r o t a t i n g torque w i t h an inch
pound torque wrench (Fig. 31). The torque necessary
to rotate the pinion gear should be:
• Original Bearings — 1 to 3 N - m (10 to 20 i n .
lbs.).
• New Bearings — 2 to 5 N - m (15 to 35 i n . lbs.).
