(14) Using yoke holder 6958 and a torque wrench
set at 474 N·m (350 ft. lbs.), crush collapsible spacer
until bearing end play is taken up (Fig. 46).
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.
(15) Slowly tighten the nut in 6.8 N·m (5 ft. lbs.)
increments until the rotating torque is achieved.
Measure the rotating torque frequently to avoid over
crushing the collapsible spacer (Fig. 47).
(16) Check bearing rotating torque with a (in. lbs.)
torque wrench (Fig. 47). The torque necessary to
rotate the pinion gear should be:
• Original Bearings—1to2N·m(10to20in.
lbs.).
• New Bearings — 1.5 to 4 N·m (15 to 35 in. lbs.).
(17) Install differential in housing.
FINAL ASSEMBLY
(1) Scrape the residual sealant from the housing
and cover mating surfaces. Clean the mating surfaces
with mineral spirits. Apply a bead of Mopart Silicone
Rubber Sealant, or equivalent, on the housing cover
(Fig. 48).
Install the housing cover within 5 minutes
after applying the sealant.
(2) Install the cover on the differential with the
attaching bolts. Install the identification tag. Tighten
the cover bolts to 41 N·m (30 ft. lbs.) torque.
CAUTION: Overfilling the differential can result in
lubricant foaming and overheating.
(3) Refill the differential housing with gear lubri-
cant. Refer to the Lubricant Specifications section of
this group for the gear lubricant requirements.
(4) Install the fill hole plug.
