12. A low contact pattern, as shown in Figure 35, indicates pinion is too deep. Set pinion to correct depth by adding
shims under pinion cage. Slight inward movement of ring gear may be necessary to maintain correct backlash.
Figure 35. Low Contact Pattern.
13. Recheck pinion gear-to-ring gear clearance for a full rotation of ring gear.
14. After establishing correct tooth contact, install two adjuster locks (Figure 36, Item 2) and new cotter pins
(Figure 36, Item 1).
15. Install lockwire (Figure 36, Item 3) on four bearing cap bolts (Figure 36, Item 4).
