Timken DRK315 rear axle differential bearing and seal kit for the 1979-2010 Ford Mustang and other vehicles supplies the parts for a differential rebuild. The differential is the rear-axle gear set that splits drive torque between the wheels.
Rear axle noise that changes with speed, or gear oil seeping around the differential housing, can come from worn bearings or a leaking seal. Find the cause first: with the engine off and cool, look over the housing for oil seepage, and leave bearing play and noise testing to a shop.
This axle differential bearing and seal kit also fits the 1983-2011 Ford Ranger and the 1991-1997 Ford Explorer, among many vehicles from Ford, Lincoln, Mazda, Mercury and Avanti.
