Axle Halfshafts

REMOVAL & INSTALLATION



See Figures 1 and 2

The following procedure only pertains to axle shafts on vehicles with multi-link rear suspensions.

On vehicles with a multi-link suspension, the axles are actually halfshafts, bolted to the differential. Each halfshaft has a constant velocity (CV)-joint at each end, allowing a full range of motion as the vehicle passes over bumps and depressions.

  1. Loosen the large halfshaft retaining nut in the center of the wheel bearing housing.
  2.  
  3. Loosen the halfshaft retaining nut.
  4.  
  5. Raise and safely support the vehicle.
  6.  
  7. Remove the wheel(s).
  8.  
  9. At the center of the vehicle, remove the eight bolts holding the upper and lower sections of the final drive housing.
  10.  
  11. Remove the bolts holding the halfshaft to the final drive unit (differential) and remove the shaft from the wheel bearing housing.
  12.  
  13. When the shaft is removed, inspect the rubber boots for any sign of splitting or cracking. The boots must be intact and waterproof or the joint within is at risk. A light coat of silicone or vinyl protectant applied to a CV-boot will extend its life.
  14.  

To install:
  1. When reinstalling, fit the threaded end (at the wheel) first, then position and secure the inboard end. Always use new, lightly oiled bolts and tighten them to 70 ft. lbs. (95 Nm).
  2.  
  3. Reinstall the lower section of the final drive housing. Before tightening the eight mounting bolts, install two 12mm long bolts (or 12mm drifts) into the centering holes and align the panel. This is essential to insure correct wheel alignment when finished.
  4.  
  5. Tighten the eight mounting bolts to 52 ft. lbs. (71 Nm) PLUS 30 degrees of rotation.
  6.  
  7. Use a new, lightly oiled halfshaft retaining nut and install it on the threaded end of the shaft. Tighten it until it is snug, but do not final-tighten at this time.
  8.  
  9. Install the wheel(s).
  10.  
  11. Lower the vehicle.
  12.  
  13. Apply the hand brake and tighten the halfshaft nut to 103 ft. lbs. (140 Nm) PLUS 60 degrees of rotation. Double check the wheel lugs for correct tightness.
