  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Drain the rear axle fluid.
  4.  
  5. Remove or disconnect the following:
    NOTE
    The brake calipers and pads or drums must be removed so that there is no additional drag when measuring pinion bearing preload.



    Driveshaft
     
    Wheels
     
    Brake calipers and pads or drums
     

  6.  
  7. Use an inch lb. torque wrench and measure and record the amount of torque required to maintain pinion rotation through several revolutions.
  8.  
  9. Remove or disconnect the following:

    Flange nut
     
    Pinion flange
     
    Pinion seal

To install:


NOTE
Use a new collapsible spacer and flange nut for assembly.

  1. Install or connect the following:

    Collapsible spacer
     
    Pinion bearing
     
    Pinion seal
     
    Pinion flange
     

  2.  
  3. Rotate the pinion flange occasionally while tightening the flange nut to make sure the pinion bearings seat correctly.
  4.  
  5. Take frequent bearing preload torque readings. Tighten the flange nut to achieve the preload torque readings originally recorded.
    CAUTION
    Never loosen the pinion nut to reduce bearing preload. If it is necessary to reduce bearing preload, install a new collapsible spacer and pinion nut. Maximum pinion nut torque should be 220-280 ft. lbs. (298-380 Nm).

  6.  
  7. Install or connect the following:

    Driveshaft. Torque to 46 ft. lbs. (63 Nm).
     
    Brake calipers and pads or drums
     
    Wheels
     

  8.  
  9. Fill the differential with gear lubricant and check for leaks.
