Detailed Description

InMotion WS470672 is a drive axle shaft seal engineered for front right axle locations where the seal must retain lubricant while keeping contaminants out of the differential area. The nitrile construction supports consistent sealing performance in demanding driveline environments, including Ford F-250 HD axle and Spicer axle configurations, as well as Ford Bronco, F-150, Ranger, Explorer, Mazda B4000, and Mazda Navajo applications listed in the fitment data. The seal dimensions are matched to the shaft and housing bore requirements to help maintain proper contact and reduce leakage at the axle interface. If you are replacing a worn front right axle seal on a Ford F-150, Ford Ranger, or Ford F-250, WS470672 provides the dimensional and application-specific coverage needed for a direct repair.

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

What It Helps Fix

• Gear oil seepage at the front right axle seal area
• Contamination entering the differential pinion or axle housing
• Seal wear from age, heat, and driveline movement
• Loss of lubricant that can affect differential operation
• Noise or driveline concerns related to low fluid level

Installation Notes and Tips

Confirm axle type, housing bore, and shaft diameter before installation. Clean the sealing surface thoroughly and inspect the axle shaft and bore for scoring, corrosion, or wear that could affect seal contact. Match the vehicle, year, and axle configuration exactly, especially on Ford F-250, F-150, Bronco, Ranger, Explorer, Mazda B4000, and Mazda Navajo front right applications. Use proper seal installation practices to avoid distortion and ensure the lip seats evenly.
