REMOVAL & INSTALLATION
See Figures 1 and 2
- Raise the vehicle and support with jackstands.
- Mark the driveshaft and pinion yoke for reinstallation. Remove the driveshaft from the pinion yoke and wire it up to the frame. Tape the U-joint caps in place to prevent dirt from entering the U-joint.
- Mark the position of the pinion yoke, pinion gear shaft and pinion yoke nut so the proper bearing preload can be maintained.
- Place a drain pan under the pinion yoke. Remove the pinion nut and washer using a pinion yoke remover J-8614-10 or equivalent.
- Remove the pinion yoke using removing tools J-8614-2, J-8614-3 and J-8614-10.
- Remove the seal with a slide hammer or by driving it out of the carrier with a blunt chisel. Do NOT damage the carrier.
- Clean all dirt, varnish, nicks and tool marks off of the yoke seal carrier with a small file or fine emery cloth.
- Install a new pinion seal using a seal installer J-23911 or J-22388.
- Lubricate the seal with differential fluid.
- Install the pinion yoke, washer and nut.
- Using the yoke holding tool, torque the nut to 1 / 16 in. (1.6mm) past the alignment marks.
- Install the driveshaft to the marks positions and lower the vehicle.
