Cherokee 4WD L6-4.0L VIN S (1998)
NOTE: Pinion depth shims are placed between the rear pinion bearing cone and pinion gear to achieve proper ring and pinion gear mesh. It the
factory installed ring and pinion gears are reused, the pinion depth shim should not require replacement. If required, refer to Pinion Gear Depth to
select the proper thickness shim before installing rear pinion bearing.
8. Place the proper thickness depth shim on the pinion gear.
Shaft Rear Bearing Installation
9. Install the rear bearing and slinger, if equipped, on the pinion gear with Installer 6448.
Collapsible Preload Spacer
10. Install a new collapsible preload spacer on pinion shaft and install pinion gear in housing.
11. Install pinion gear in housing.
12. Install yoke with Installer C-3718 and Yoke Holder 6719.
13. Install the yoke washer and a new nut on the pinion gear and tighten the pinion nut until there is zero bearing end-play. It will not be possible at
this point to achieve zero bearing end-play if a new collapsible spacer was installed.
14. Tighten the nut to 285 Nm (210 ft. lbs.).
CAUTION: Never loosen pinion gear nut to decrease pinion gear bearing rotating torque and never exceed specified preload torque. If preload
torque or rotating torque is exceeded a new collapsible spacer must be installed. The torque sequence will then have to be repeated.
