Durango 4WD V8-5.9L VIN Z (1998)
Collapsible Preload Spacer
9. Install a new collapsible preload spacer on pinion shaft and install pinion gear in housing.
10. Install pinion gear in housing.
11. Install yoke with Installer C-3718 and Yoke Holder 6719.
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. It will not be possible at
this point to achieve zero bearing end-play if a new collapsible spacer was installed.
13. 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.
14. Using Yoke Holder 6719, crush collapsible spacer until bearing end play is taken up.
Check Pinion Gear Rotating Torque
15. Slowly tighten the nut in 6.8 Nm (5 ft. lbs.) increments until the desired rotating torque is achieved. Measure the rotating torque frequently to
avoid over crushing the collapsible spacer.
16. 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.).
17. Install propeller shaft.
