REMOVAL & INSTALLATION
See Figures 1, 2, 3 and 4
- Raise and safely support the front end on jackstands.
- Matchmark and disconnect the driveshaft from the yoke.
- Using a yoke holding tool, such as J-8614-01, or its equivalent on the yoke, and remove the pinion nut.
- Remove the yoke, using tools J-8614-01, -02, and -03, or their equivalents.
- Using tool seal removal tool -25180, or its equivalent, remove the seal.
- Coat the new seal's outer rim with sealer, then install it using a driver.
- Install the yoke, pinion washer and a new pinion nut. Torque the nut to 210 ft. lbs. (285 Nm).
- Connect the driveshaft, then check and refill the differential housing fluid as necessary.
See Figures 5, 6, 7 and 8
- Raise and support the vehicle safely.
- Matchmark and remove the driveshaft.
- Rotate the pinion gear three or four times with a torque wrench attached to the yoke nut. Measure the amount of torque necessary to rotate the pinion. Note for installation reference.
- Matchmark the pinion yoke and gear for installation reference.
- Using a holding tool, remove the pinion yoke nut and washer. Discard the nut.
- Punch the seal with a pin punch and pry it from the seal bore.
- Apply gear lubricant to the lip of the replacement seal and install using a seal installation tool.
- Install the yoke, noting the reference marks. Tighten just enough to remove the end-play.
Set bearing preload as follows:
- The required pinion gear bearing preload torque is 6 inch lbs. (0.7 Nm) over the noted release torque as measured above.
- Rotate the pinion gear three or four times with a torque wrench attached to the yoke nut. Measure the amount of torque necessary to rotate the pinion.
- Using a holding tool and tighten the yoke nut in small increments and remeasure until the specified torque is obtained.
- Install the driveshaft. Torque the strap bolt nuts to 14 ft. lbs. (19 Nm).
New strap bolts be used whenever the driveshaft is disconnected.
- Add lubricant if necessary. Lower vehicle.
