The procedure to remove and install axle shafts on vehicles that have multi-link rear suspensions consists of several steps. First, loosen the large halfshaft retaining nut in the middle of the wheel bearing housing, then loosen the halfshaft retaining nut. Next, jack up and safely support the vehicle and take off the wheel(s). At the center of the car, delete the eight bolts that secure the upper and lower pieces of the final drive housing. After that, remove bolts that support the halfshaft to the final drive unit (differential), and remove the shaft from the wheel bearing housing. Upon removal, examine the rubber boots for any evidence of splitting or cracking and make sure they are intact and waterproof to ensure protection to the joint. To install, fit the thread end at the wheel and then knock up and fit the inboard end by using new bolts that have been lightly oiled, tighten to 70 ft-lbs (95 Nm). Reinstalling the lower section of the final drive housing, and before the tightening of the eight mounting bolts, insert two 12mm long bolts or drifts in the centering holes to align the panel for proper wheel alignment. Tighten the eight mounting bolts 52 ft-lbs (71 Nm) plus an additional 30 degrees of rotation. Use a new, lightly oiled halfshaft retaining nut on the threaded end of the shaft and tighten it until it is snug, but not quite all the way. After installation of the wheel(s) and lowering the vehicle, engage the hand brake and tighten the halfshaft nut to 103 ft-lbs (140 Nm) plus 60 degrees of rotation, being sure to double check the wheel lugs for proper tightness.
