10. Use Flange Wrench 6958, a length of 1 inch pipe and a torque wrench set at 500 Nm (368 ft. lbs.) and crush collapsible spacer until bearing end
play is taken up (Fig. 62).
11. 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. 63).
12. Rotate the pinion a minimum of ten times. Verify pinion rotates smoothly and check rotating torque with an inch pound torque wrench (Fig. 63).
Pinion gear rotating torque is:
-
Original Bearings: 1 - 2.25 Nm (10 - 20 in. lbs.).
-
New Bearings: 1.7 - 3.4 Nm (15 - 30 in. lbs.).
13. Invert the differential case and start two ring gear bolts. This will provide case-to-ring gear bolt hole alignment.
14. Invert the differential case in the vise.
