Grand Cherokee 2WD L6-4.0L VIN S (1997)
12. Install the yoke washer and a new nut on the pinion gear and tighten the pinion nut until there is zero bearing end-play.
13. Tighten the nut to 271 Nm (200 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.
14. Using yoke holder 6958, or equivalent 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 (60 inch 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 6 Nm (15 to 35 inch lbs.).
17. Install differential in housing.
