Axle Vent

NOTE: If a plugged vent cannot be cleared, install a new vent.

A plugged vent or vent hose will cause excessive seal lip wear due to internal pressure buildup. If a leak occurs, check the vent and the vent hose. Remove the hose from the vent nipple and clear the hose of any foreign material. While the hose is removed, pass a length of mechanics wire or a small diameter Allen wrench in and out of the vent to clean it. Connect the hose when done.
