Disassembly

1. Before disassembling the differential, measure and record the backlash of the pinion gears as follows:
a. Install both driveshaft on differential assembly.
b. Support driveshafts on V-blocks, then measure backlash of both pinion gears. Correct measurement is 0.000-0.004 inch.
2. Remove eight bolts which secure ring gear to gear case. Tap ring gear around its circumference with a soft mallet to loosen. Remove ring gear from gear case.
3. Mount gear case in a vise equipped with soft jaws. Do not exert excess pressure on vise.
4. Remove pinion shaft roll pin using a 4mm diameter rod at least 3 inches long, and a hammer. Drive roll pin free on gear case.
5. Press front differential bearing from gear case using bearing puller attachment tool No. D84L-1123-A and step plate adapter tool No. D80L-630-3 or equivalents.
6. Remove rear differential bearing from gear case using puller tool No. T77F-4220-B and step plate adapter toll No. D80L-630-3 or equivalents.
