side opposite gear only enough to notice end play on the indicator.

(2)

Tighten the same adjusting ring (74) only enough to obtain 0.000 end play.

(3)

Check the ring gear (77) for run-out. If run-out exceeds 0.008 in. (0.203 mm), remove the differential and

check for cause.

(4)

Starting with 0.000 end play, tighten each adjusting ring (74) one notch. This will properly preload the dif-

ferential bearings.

Check Hypoid Gear Backlash. If the ring gear (77) is not going to be replaced, the established backlash recorded

before disassembly should be used. For new ring gears the new backlash should be initially set at 0.010 in. (0.254

mm). Adjust backlash by moving the ring gear only. This is done by backing off one adjusting ring (74) and

advancing the opposite ring the same amount.
