Install the nut onto the pinion shaft using a torque wrench, the
J 42172 (1), and the
DT-48007 (2).
Tighten Tighten the nut to 500 N·m (370 lb ft).
Using a punch, stake the areas of the nut into the notches in the end of the pinion shaft.
Measure the rotating torque of the pinion shaft using the
DT-48007 . A properly assembled pinion shaft and bearings should have a rotating torque of 1.4-2.8 N·m (12-25 lb in).
