Dorman describes this part as a differential vent breather, so it is listed under both names. Its job is mechanical: it lets air move in and out of the front axle housing, which helps relieve pressure changes that could otherwise push gear oil toward the seals.
Signs this part may need replacing include a vent clogged with dirt or debris, or gear oil seeping around the axle seals or vent. Find the source of any leak before you replace parts.
