Conclusion

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.

Conclusion

Axle hub seals, often referred to as axle seals or differential seals, are located at the junction of the axle housing and the axle shaft. Their primary purpose is to keep the lubricating oil inside the axle housing while preventing dirt, moisture, and other debris from entering. Made from durable materials like rubber or polymer, these seals are engineered to withstand high temperatures, pressure, and the harsh conditions typically encountered in automotive environments.

1. O-rings These are circular rubber gaskets that create a seal between different components. O-rings are crucial for preventing fluid leakage and are commonly used in hydraulic systems.

   - Shut down the system: Before beginning the replacement procedure, ensure that the system is safely shut down to prevent accidents and injuries.

3. Disassembly Remove the hydraulic cylinder from its mounting. Carefully disassemble the cylinder by unscrewing the end caps and sliding out the piston rod.
