Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell. The sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.

There are several signs that indicate a rear hub seal may be failing. One of the most common symptoms is a leak of oil around the rear wheels. This can often be seen as a puddle of oil forming underneath the car, or as oil splattered on the inside of the wheels. It is crucial to address this issue promptly, as leaking oil can not only damage the axle components but also pose a safety hazard due to reduced traction.

4. Facilitating Smooth Operation Oil seals contribute to the smooth operation of rotating shafts by minimizing vibration and noise. When installed correctly, they help maintain a consistent lubricating film around the moving parts, providing a balanced environment where wear is minimized, and performance is maximized.
