What This Seal Helps Address

• Gear oil seepage at the rear inner wheel-end seal area
• Contamination entering the axle or hub sealing surface
• Wear-related leakage on aging Mercedes-Benz rear axle assemblies
• Seal mismatch when servicing OE-style import driveline components
• Noise or maintenance issues caused by compromised wheel-end sealing

Installation Notes and Tips

Verify housing bore, shaft diameter, and seal width before installation to confirm the correct wheel seal for your application. Clean the sealing surfaces thoroughly and inspect the axle shaft and housing for wear, scoring, or corrosion that could affect seal life. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
