Its nitrile material helps maintain a reliable barrier at the sealing surface, reducing the chance that debris and moisture reach sensitive internal components.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Gear oil seepage at the front inner wheel seal area

Installation Notes and Tips

The WS9406S is specified for front inner locations only, so confirm the vehicle year, make, model, and brake configuration against the fitment list before service. Clean the sealing surfaces thoroughly and inspect the mating components for wear or scoring before installing the new seal.
