Leaks

Most rear axle leakage conditions can be corrected without a teardown. However, it is important to clean the leaking area enough to identify the exact source. A plugged or seized rear axle housing vent will cause excessive flange yoke seal lip wear due to internal pressure buildup. When a leak occurs, check vent and vent tube for debris. Clean or replace as required. Check axle lubricant level. Adjust as required to 12.7-14.3 mm (0.50-0.56 inch) just below bottom of fill plug hole.
