case. Install left axle shaft into rear housing. Tighten nuts
diagonally to 36-43 ft. lbs. (49-58 N.m).
5) Install right axle shaft without shims and "O" ring.
Temporarily tighten to about 53 INCH lbs. (6 N.m). Using a feeler
gauge, measure clearance between bearing case and rear axle housing.
6) Remove right axle shaft. Install shims to equal bearing
case-to-axle housing clearance plus .002-.008" (.05-.20 mm). Install
"O" ring to right rear axle housing. Apply sealant to mating surfaces
of bearing case and shim. See Fig. 10.
