REMOVAL & INSTALLATION
See Figures 1, 2 and 3
- Raise and safely support the vehicle.
- Remove both rear wheel and tire assemblies.
- Matchmark the driveshaft and pinion yoke so they may be reassembled in the same position. Remove the driveshaft.
- Using a suitable inch pound torque wrench on the pinion yoke nut, measure and record the pinion bearing, axle bearings and seal preload.
- Using a suitable tool to hold the pinion yoke in place, remove the pinion yoke nut and washer.
- Place a suitable container under the differential to catch any fluid that may drain from the rear axle. Using a suitable tool, remove the pinion flange.
- Use a suitable tool to remove the pinion seal.
- Inspect the seal surface of the pinion flange for tool marks, nicks or damage and replace, as necessary. Examine the carrier bore and remove any burrs that might cause leaks around the outside of the seal.
- Install the seal 0.010 in. (0.25mm) below the flange surface using a suitable seal installer.
- Apply suitable seal lubricant to the outer diameter of the pinion flange and the sealing lip of the new seal.
- Install the pinion flange on the drive pinion by taping with a soft hammer until a few pinion threads project through the pinion flange.
- Install the washer and pinion flange nut. While holding the pinion flange, tighten the nut a little at a time and turn the drive pinion several revolutions after each tightening, to set the bearing rollers. Check the preload each time with a suitable inch pound torque wrench until the preload is 5 inch lbs. (0.6 Nm) more then the reading obtained during disassembly.
- Install the driveshaft.
- Install the rear wheels and tires. Check and add the correct lubricant, as necessary.
