Axle Vent

NOTE: If rear axle housing vent cannot be cleared, it must be replaced.

- A plugged rear axle housing vent will cause excessive seal lip wear due to internal pressure buildup. When a leak occurs, check the rear axle housing vent which is located near the top of the differential housing.
- Make sure the vent hose is not kinked. Remove the vent hose from the vent nipple and make sure the hose is clear of dirt or other foreign materials.
- While hose is removed, pass a length of wire or small diameter Allen wrench in and out of the vent nipple to clean it of any dirt or foreign materials. Install vent hose.
- Make sure axle lubricant is level with bottom of fill hole.
