RA-38 REAR AXLE AND SUSPENSION — Differential (d) Recheck the ring gear backlash. Backlash: 0.13 — 0.18 mm (0.0051 — 0.0071 in.) (e) If not within standard, adjust by either increasing or decreasing the washers on both sides by equal amount. HINT: The backlash will change about 0.02 mm (0.0008 in.) with 0.03 mm ( 0.0012 in.) alteration of the side washer.

INSPECT TOOTH CONTACT BETWEEN RING GEAR AND DRIVE PINION (a) Coat 3 or 4 teeth at three different position on the ring gear with red lead. (b) Hold the companion flange firmly and rotate the ring gear in both directions. (c) Inspect the tooth pattern.
