Fel-Pro Differential Cover Gaskets
Vehicles manufactured after 1990 often have differential housings sealed with RTV silicone. Over time, extreme vehicle vibration and even rough roads can cause the RTV bead to break. If the bead breaks and the vehicle loses the axle lube, the transmission gears begin to rub and wear. That's the whining sound that you hear. Unfortunately, it's a repair that needs immediate attention. Fel-Pro offers precut differential replacement gaskets for these applications, so you won't have to worry about applying RTV and waiting for it to set up to seal. These gaskets are available in a variety of materials, thicknesses, and configurations for precise fitment on nearly 70 differential case designs. Order the model recommended for your application—and eliminate the need for messy RTV sealant.
