Cherokee 2WD L6-4.0L VIN S (1998)
7. Seat yoke on pinion shaft with Installer C-3718 and Wrench 6719.
8. Remove the tools and install the pinion yoke washer. The convex side of the washer must face outward.
CAUTION: Do not exceed the minimum tightening torque when installing the pinion yoke retaining nut at this point. Damage to collapsible
spacer or bearings may result.
Tightening Pinion Shaft Nut
9. Hold pinion yoke with Yoke Holder 6719 and tighten shaft nut to 285 Nm (210 ft. lbs.). Rotate pinion shaft several revolutions to ensure the
bearing rollers are seated.
Check Pinion Rotation Torque
10. Rotate the pinion shaft using an (inch lbs.) torque wrench. Rotating torque should be equal to the reading recorded during removal, plus an
additional 0.56 Nm (5 inch 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.
11. If the rotating torque is low, use Yoke Holder 6719 to hold the pinion yoke and tighten the pinion shaft nut in 6.8 Nm (5 ft. lbs.)increments until
proper rotating torque is achieved.
NOTE: The bearing rotating torque should be constant during a complete revolution of the pinion. If the rotating torque varies, this indicates a
binding condition.
