Detailed Description

WS711054 is a differential pinion seal engineered for a tight, reliable seal in the driveline. The fluoro-elastomer material supports long-term sealing performance, while the listed dimensions help ensure proper seating in the housing bore and around the shaft. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. For buyers searching for a Chrysler 300 rear differential pinion seal or a Mercedes-Benz S500 rear axle seal, WS711054 provides a direct replacement path for the specified axle setups.

What It Helps Address

• Gear oil seepage at the differential pinion seal area.
• Contamination from dirt, water, and road debris entering the differential.
• Wear on internal differential components caused by loss of lubricant.
• Seal deterioration from age, heat, and fluid exposure.

Installation Notes and Tips

Verify axle type before ordering, since fitment is limited to vehicles with the listed ZF or Mercedes-Benz axle configurations. Clean the sealing surface thoroughly and inspect the housing bore and shaft area for wear before installation. Confirm the part number WS711054 against the vehicle application to avoid mismatch.
