Removal & Installation



  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Remove or disconnect the following:

    Rear driveshaft by matchmarking it
     
    Companion flange nut, by loosen the staked portion
     
    Companion flange, using a screw-type extractor
     
    Oil seal, using an extractor
     

  4.  

To install:

  1. Install a new oil seal, to a depth of 0.039 in. (1.0mm) below the lip, using a seal driver.
  2.  
  3. Lubricate the seal lip with multi-purpose grease.
  4.  
  5. Install or connect the following:

    Companion flange, coat the threads with multi-purpose grease
     
    New companion flange nut. Tighten it to 109 ft. lbs. (147 Nm).
     

  6.  
  7. Measure the bearing preload, using a torque wrench. The correct preload should be 8-11 inch lbs. (0.9-1.2 Nm) for a 2 spider gear differential or to 4-7 inch lbs. (0.4-0.8 Nm) for a 4 spider gear differential.
    NOTE
    If the preload is greater that specified, replace the bearing spacer. If the preload is less than specified, tighten the companion flange nut in 9 ft. lbs. (13 Nm) increments until the correct preload is achieved. Maximum torque for the nut is 325 ft. lbs. (441 Nm). If the value is exceeded, the bearing spacer must be replaced; do not back off the flange nut to lower the torque or preload.
