Grand Cherokee 4WD V8-4.7L (2003)
4. Install yoke with Installer C-3718 and Spanner Wrench 6958 (Fig. 39).
5. Install yoke washer and new nut on the pinion gear. Tighten the nut to remove all end-play. Tighten the nut to a minimum torque of 298 Nm (220
ft. lbs.).
CAUTION: Never loosen pinion gear nut to decrease pinion rotating torque and never exceed specified preload torque. If preload torque or
rotating torque is exceeded a new collapsible spacer must be installed.
NOTE: New collapsible spacers require high initial torque to start the collapsing of the spacer. This may reach 678 Nm (500 ft. lbs.).
6. Hold yoke with Spanner Wrench 6958 and a torque wrench set at 380 Nm (280 ft. lbs.), (Fig. 40) 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 (Fig. 41).
