14. Using yoke holder 6958, a short length of 1 inch pipe, and a torque wrench set at 474 Nm (350 ft. lbs.), crush collapsible spacer until bearing end
play is taken up (Fig. 56).
NOTE: If the spacer requires more than 474 Nm (350 ft. lbs.) torque to crush, the collapsible spacer is defective and must be replaced.

15. Slowly tighten the nut in 6.8 Nm (5 ft. lbs.) increments until the required rotating torque is achieved. Measure the rotating torque frequently to
avoid over crushing the collapsible spacer (Fig. 57).
16. Rotate the pinion a minimum of ten times. Verify that the pinion rotates smoothly. Check bearing rotating torque with an inch pound torque
wrench (Fig. 57). The torque necessary to rotate the pinion gear should be:
-
Original Bearings - 1 to 2.25 Nm (10 to 20 inch lbs.).
-
New Bearings - 1.7 to 3.4 Nm (15 to 30 inch lbs.).
17. Install differential in housing.
