Ring-to-Drive Pinion Gear Backlash
With differential bearing preload set, remove inspection hole cover, mount dial indicator in one cover bolt hole, and check ring-to-pinion gear backlash. Check ring gear tooth contact pattern.
NOTE:
Refer to Rear Axle Gear Tooth Patterns in this section.
While maintaining established shim thickness, move shims behind carrier bearing outer cones, from one side to the other as necessary, to obtain proper contact pattern. After setting backlash, complete differential reassembly procedure.
