9-6. REAR PLANETARY WHEEL ENDS REPLACEMENT (CONT)
Preload wheel bearings.
Seat bearings and related components by tightening the nut (15) to 100 lb-ft (135.58 N·m)
while wheel hub (2) is rotated in both directions.
Back off nut (15) to relieve preload on bearings. Torque on nut should be 0 lb-ft (0 N·m).
Use fabricated hub drag tool and a torque wrench to check rolling torque while hub is rotating
at a steady rate (not starting torque). Record torque.
Tighten nut (15) and check hub rolling torque again. The increase in rolling torque from zero
preload should be 3 - 5 lb-ft (4.07 - 6.78 N·m) for new bearings.
If bearings are to be reused, the increase in rolling torque should be 1.5 - 2.5 lb-ft
(2.03 - 3.39 N·m).
