The axle seal connects the axle to the rear differential or the transmission. The purpose of the axle seal is to keep transmission/Diff fluid from leaking, allowing the transmission/Diff to run smoothly and reliably. A significant loss of transmission/Diff fluid can affect the overall performance of the transmission and Differential. The Dorman Axle Differential Seal is made of quality materials to prevent axle fluid leaks and prevent harmful contaminants from entering the transmission. Additionally, our axle differential seal is easy to install, a direct replacement, and ensures an exact fit every time. All Dorman products are engineered in the United States and backed by 100 years of automotive aftermarket experience. Our solutions are thoroughly tested and inspected, and if you experience any difficulty installing or using our parts, we have a dedicated technical support team of ASE Blue Seal certified professionals ready to help.
