Grand Cherokee 2WD V8-5.2L VIN Y (1998)
Pinion Yoke Installation
8. Install yoke, or flange, with Installer W-162-B, Cup 8109, and Holder 6958.
9. Install the pinion washer and a new nut on the pinion gear. Tighten the nut to 216 Nm (160 ft. lbs.) minimum. Do not over-tighten. Maximum
torque is 352 Nm (260 ft. lbs.).
CAUTION: Never loosen pinion gear nut to decrease pinion gear bearing rotating torque and never exceed specified preload torque. If preload
torque is exceeded a new collapsible spacer must be installed. The torque sequence will then have to be repeated.
NOTE: If the spacer requires more than 352 Nm (260 ft. lbs.) of torque to crush, the collapsible spacer is defective.
Tightening Pinion Nut
10. Using Holder 6958, a short length of 1 inch pipe, and torque wrench set at 352 Nm (260 ft. lbs.), crush collapsible spacer until bearing end play is
taken up.
Check Pinion Gear Rotation Torque
11. 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.
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.).
