12 bolt car rear end cover gasket

The differential gasket is the gasket that seals the differential housing. It's typically manufactured out of cork, rubber, or an oil-resistant silicone that seals the two-piece differential case. This gasket is intended to keep rear-end grease and oil contained within the housing but also reduce dirt, debris or other harmful particles from entering the rear end differential. Rear-end oil and grease is essential in properly lubricating the ring and pinion gears that supply power to drive axles.

When this gasket fails, the lubricants will leak from the rear end housing and can cause these expensive components to wear out or break entirely.

It's very rare that the differential gasket wears out or breaks. In fact, some differential gaskets made in the 1950s and 1960s are still on their original vehicles. However, if a problem does occur with the gasket, like any other mechanical defect it will display a few common warning signs or symptoms that should alert the vehicle owner that a problem exists.
