Grand Cherokee 2WD V8-5.2L VIN Y (1998)
Tightening Pinion Nut
14. Using yoke holder 6958, a short length of 1 inch pipe, and a torque wrench set at 474 Nm (350 ft. lbs.), crush collapsible spacer until bearing end
play is taken up.
NOTE: If the spacer requires more than 474 Nm (350 ft. lbs.) torque to crush, the collapsible spacer is defective and must be replaced.
15. Slowly tighten the nut in 6.8 Nm (5 ft. lbs.) increments until the rotating torque is achieved. Measure the rotating torque frequently to avoid over
crushing the collapsible spacer.
16. Check bearing rotating torque with an inch pound torque wrench. The torque necessary to rotate the pinion gear should be:
-
Original Bearings - 1 to 3 Nm (10 to 20 inch lbs.).
-
New Bearings - 2 to 5 Nm (15 to 35 inch lbs.).
17. Install differential in housing.
Rear Axle - 216RBI
NOTE: The ring and pinion gears are service in a matched set. Do not replace the pinion gear without replacing the ring gear.
REMOVAL
1. Remove differential assembly from axle housing.
2. Mark pinion yoke and propeller shaft for installation alignment.
3. Disconnect propeller shaft from pinion yoke. Using suitable wire, tie propeller shaft to underbody.
