Dorman - OE Solutions Axle Vent P/N:924-263
Give the front axle room to breathe with the Dorman axle vent, part number 924-283. This differential vent breather lets the axle housing relieve pressure as it heats and cools. It fits many vehicles, among them the 1999-2020 Ford F-250 Super Duty, 1999-2020 Ford F-350 Super Duty and 1999-2020 Ford F-450 Super Duty. See the "Vehicles it fits" section for the full list and engine details.
Air inside the axle housing expands and contracts as the gear oil warms and cools. The vent gives that air an outlet, which helps keep pressure from building up behind the seals. If a blocked or broken vent is behind gear-oil seepage, this Dorman differential vent is designed to replace it.
Signs this part may need replacing include gear oil weeping from the axle seals or around the housing, or a vent that is cracked, missing or clogged with dirt. Diagnose the cause of any leak before replacing parts.
