How to Detect and Repair an Output Shaft Seal Leak

AvatarByCarl Frisch

An output shaft seal leak is a common issue in vehicles, and can be a major cause of vehicle breakdowns. The output shaft seal is the seal located between the transmission and the driveshaft, and its primary purpose is to keep oil from leaking out of the transmission. If the output shaft seal starts to leak, it can cause a variety of problems, including a decrease in fuel efficiency, poor engine performance, transmission slippage or failure, and even potential damage to other components. It’s important to address a leak as soon as possible in order to avoid more costly repairs down the line. To fix an output shaft seal leak, you’ll need to replace the seal itself. This can be done by removing the driveshaft and replacing the seal with a new one.
