- Place differential case in holding fixture or vise. Lubricate side and pinion gears and all thrust washers. Install in case. Rotate side gears until holes in pinion gears and washers line up with holes in case.
- Install spacer block (if equipped) and differential pinion shaft. If old thrust washers are used, check for preload of side gears. Clearance between side gears and case should be 0.000 - 0.006" (0 - 0.15 mm). If not, shims can be installed (at least 1 on each side) or new thrust washers used.
- Install lock pin, and peen over hole to retain pin. Inspect ring gear and case for burrs and nicks. Install ring gear, and tighten bolts evenly. Install differential side bearings. Assemble case in housing without shims.
Check end play without shims installed in case.
- Install bearing caps, and tighten bolts just enough to seat bearing cups. Mount dial indicator to read at back of differential flange. Measure and record amount of side play of differential case by moving it back and forth with a screwdriver. See Fig 1.
- The measurement will be used later to determine proper shim pack dimension. Remove case from housing.
