Cherokee 4WD L6-4.0L VIN S (1998)
Tightening Pinion Nut-Typical
14. Using yoke holder 6958 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.
Check Pinion Gear Rotating Torque
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 a (inch lbs.) 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.
8 1/4 Axle
The ring and pinion gears are serviced in a matched set. Do not replace the pinion gear without replacing the ring gear.
REMOVAL
1. Remove differential from the 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.
4. Using Yoke Holder 6719 to hold yoke and remove the pinion yoke nut and washer.
