The rear axle is specially equipped with a vent tube filter to protect the axle from contaminants found in the off-road environment. It is attached to a hose with a vented cap at the end. The rear axle vent filter is mounted near the top of the axle housing and the hose is attached to the brake bracket on the driver’s side frame rail.

The filter must be inspected occasionally to see if it needs to be replaced. Refer to Owner Checks and Services in Maintenance and Lubrication.
