  11. Press off the bearing and install the new one by pressing it into position.
  12.  
  13. Press on the new retainer.
  14.  

Do not attempt to press the bearing and the retainer on at the same time.

To install:

  1. Pack the cavity between the seal lips with wheel bearing lubricant and lubricate a new wheel bearing with the same.
  2.  
  3. Using a suitable driver, install the bearing until it bottoms against the tube. Install the oil seal.

  5. Slide the axle shaft into place. Be sure that the splines on the shaft do not damage the oil seal. Make sure that the splines engage the differential side gear.
  6.  
  7. Install the axle shaft "C" lock on the inner end of the axle shaft and push the shaft outward so that the "C" lock seats in the differential side gear counterbore.
  8.  
  9. Position the differential pinion shaft through the case and pinions, aligning the hold in the case with the hole for the lockscrew.
  10.  
  11. Install the pinion shaft lockscrew. Using a new gasket, install the carrier cover. Be sure that the gasket surfaces are clean before installing the gasket and cover.
  12.  
  13. Fill the axle with lubricant to the bottom of the filler hole.
