REMOVAL AND INSTALLATION (Continued)
(9) Slowly tighten the nut in 6.8 N·m (5 ft. lbs.)
increments until the rotating torque is achieved.
Measure the rotating torque frequently to avoid over
crushing the collapsible spacer (Fig. 23).
(10) Check rotating torque with an inch pound
torque wrench (Fig. 23). The torque necessary to
rotate the pinion gear should be:
• Original Bearings — The reading recorded dur-
ing removal, plus an additional 0.56 N·m (5 in. lbs.).
• New Bearings — 2 to 5 N·m (15 to 35 in. lbs.).
