Grand Cherokee 2WD L6-4.0L VIN S (1997)
9. Install the yoke washer and a new nut on the pinion gear. Tighten the nut to 298 Nm (220 ft. lbs.) minimum. Do not over-tighten. Maximum
torque is 380 Nm (280 ft. lbs.).
CAUTION: Never loosen pinion gear nut to decrease pinion gear bearing preload torque and never exceed specified preload torque. If preload
torque is exceeded a new collapsible spacer must be installed. The torque sequence will have to be repeated.
NOTE: If the spacer requires more than 280 ft. lbs. torque to crush, the collapsible spacer is defective.
10. Using yoke holder 6958, or equivalent, a short length of 1 inch pipe, and a torque wrench set at 380 Nm (280 ft. lbs.), crush collapsible spacer
until bearing end play is taken up.
11. 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.
12. 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.).
13. Align previously made marks on yoke and propeller shaft and install propeller shaft.
14. Install differential housing into the axle housing.
