DR3Z-4022-A
- Description:
This genuine Ford part is the rear axle housing vent hose assembly for the 2011-2014 Mustang equipped with the 8.8-inch solid rear axle, cataloged by Ford as a Hose Assembly under part number DR3Z-4022-A. The axle vent, or breather, allows air pressure inside the differential housing to equalize as the gear oil heats and expands during driving; without a working vent, internal pressure builds and forces gear oil past the axle and pinion seals. This revised hose routes the vent higher in the chassis to reduce the chance of water intrusion and to relieve the pressure that causes the common leaky-axle-vent condition on these cars. Owners who need this part are usually chasing gear oil weeping from the axle tube seals or the differential cover area, a whistling or hissing vent, or contamination after fording water. Installation involves routing the hose from the axle housing fitting up along the chassis and securing the open end above the axle, keeping it clear of debris and standing water. Fitting the correct OEM vent hose restores proper differential breathing, protects the axle seals from being pushed out, and helps prevent repeat gear oil leaks. This is the factory Ford service hose for the 8.8 rear axle on the 2011-2014 Mustang.
