Replacement (See: Pinion Flange/Service and Repair) .
11. Using an inch-pound torque wrench, measure the rotating torque of the pinion should be between1.0-2.3 Nm (10-20 lb in) for used bearings, or
1.7-3.4 Nm (15-30 lb in) for new bearings.
12. If the rotating torque measurement is below1.0 Nm (10 lb in) for used bearings, or1.7 Nm (15 lb in) for new bearings, continue to tighten the
pinion nut in small increments, until the torque required in order to rotate the pinion is between1.0-2.3 Nm (10-20 lb in) for used bearings, or
1.7-3.4 Nm
(15-30 lb in) for new bearings.
13. Once the specified torque is obtained, rotate the pinion several times to ensure the bearings have seated.
14. Recheck the rotating torque of the pinion bearing and adjust if necessary.
15. Install the differential assembly. Refer to Differential Replacement (8.6, 9.5/9.5 LD Inch Axles) (See: Service and Repair/Removal and
