    Removal & Installation



    Dana 60 And 70 Semi-Floating Axles
    1. Before servicing the vehicle, refer to the Precautions Section.
    2.  
    3. Raise the vehicle on a hoist or raise the rear end of the vehicle with a jack. Install safety stands under the frame rails and lower the jack or hoist enough to allow the rear axle to drop into the rebound position for working clearance.
    4.  
    5. Remove the rear wheel and tire assembly.
    6.  
    7. Remove the brake disc.
    8.  
    9. Remove the differential housing cover and drain the lubricant. Clean the gasket material from the differential housing cover and the differential housing.
      WARNING
      The differential assembly is equipped with either a Loctite® coated differential pinion shaft lock screw or a differential pinion shaft lock screw with torque prevailing threads. The Loctite® treated differential pinion shaft lock screw has a 5 / 32 inch hexagram socket head. Never, under any circumstance, reuse a Loctite® coated screw after removing it. Always discard the screw and install a new one. The torque prevailing differential pinion shaft lock screw has a 12-point drive head. This type of screw is reusable for no more than four installations. When in doubt about the number of installations of a torque prevailing differential pinion shaft lock screw, discard it and install a new screw.

    10.  
    11. Remove the lock screw.

    14.  
    15. Push the flanged end of the axle shaft toward the center of the axle and remove the U-washer.
      WARNING
      Do not damage the wheel bearing oil seal when removing the axle shaft.  


      WARNING
      Do not rotate the differential side gears when removing the axle shaft. Rotating the differential side gears causes the differential pinion gears and differential pinion thrust washers to turn to the differential case opening and fall out of the differential case.

    16.  
    17. Remove the axle shaft.
      WARNING
      Install the differential pinion shaft and the old lock screw (finger-tight) to prevent the differential side gears and differential pinion gears from rotating and falling out of the differential case.

    18.  
    19. Install the differential pinion shaft and the old lock screw in the differential case.
      WARNING
      It is not necessary to remove the rear wheel bearing if only installing a new wheel bearing oil seal. To remove only the wheel bearing oil seal, pry it from the axle tube. Do not damage the seal seating surface. If removing the rear wheel bearing and the oil seal, proceed to the following step.

    20.  
    21. Remove the wheel bearing oil seal from the axle tube. Discard the seal.
      CAUTION
      Make sure protective eyewear is in place. Failure to follow these instructions may result in personal injury.

    22.  
    23. Using the special tools, remove the rear wheel bearing and the wheel bearing oil seal as a unit. Discard the seal and the bearing.
      WARNING
      The bearing and seal seating surfaces must be free from burrs, nicks, and spalling.

    24.  
    25. Clean and inspect the bore in the axle tube. Wipe the bore in the axle tube with emery cloth to smooth the surface. Clean the bore with a standard metal-cleaning solvent. Wipe the bore with a soft, lint free cloth to remove any foreign material.
    26.  

    To install:

    1. If removed, lubricate the new rear wheel bearing with the specified axle lubricant.
      WARNING
      Install the rear wheel bearing with the identification numbers facing outward.


      WARNING
      Do not cock the rear wheel bearing in the axle tube.

    2.  
    3. Using the special tools, install the rear wheel bearing.
      WARNING
      Do not cock the wheel bearing oil seal in the axle tube.


      NOTE
      The following step shows an alternate method for installing the wheel bearing oil seal.

      WARNING
      Clean the mounting surface on the differential housing cover and the differential housing with a suitable solvent to remove all traces of oil film.  


      WARNING
      The differential housing cover uses silicone rubber sealant material as a gasket. Install the differential housing cover within 15 minutes of applying the silicone or it will be necessary to apply new sealant.

    20.  
    21. Apply a continuous bead of silicone sealant to the differential housing cover mounting surface.
    22.  
    23. Assemble two bolts into the differential housing cover at the eight o'clock and two o'clock positions. Using the two bolts as a guide, position the differential housing cover on the differential housing.
    24.  
    25. Install the remaining bolts. Tighten the bolts alternately and evenly. Tighten Grade 5 bolts to 47 Nm (35 ft. lbs. Tighten Grade 8 bolts to 61 Nm (45 ft. lbs.
      WARNING
      Allow 1 hour cure time before filling the axle with the correct amount of specified lubricant and operating the vehicle.  


      WARNING
      For limited-slip axles, first fill the axle with 7 ounces of friction modifier.

    26.  
    27. Fill the differential housing with 3.0L (6.3 pints) of the specified rear axle lubricant. For additional information, refer to Specifications.
