1. Measure backlash between ring gear (Figure 31, Item 1) and pinion gear (Figure 31, Item 2) with a dial
indicator as shown.
2. Backlash is adjusted by backing off one adjuster (Figure 31, Item 5) and tightening opposite adjuster (Figure
31, Item 4) an equal amount. When backlash adjustment is within allowable limit of 0.008 to 0.015 in. (0.203 to
0.381 mm), add a light preload by tightening adjuster (Figure 31, Item 5) on tooth side ring gear an additional
1-1/2 to 2 notches.
3. Torque four bearing cap bolts (Figure 31, Item 3) to 150 to 175 lb-ft (203 to 237 Nm).
