Detailed Description

The InMotion WS8835S is engineered for rear differential sealing where precise fit and reliable containment matter. Its nitrile construction helps maintain a secure seal around the pinion shaft, while the steel case and spring materials support stable performance under drivetrain load. This part is a strong match for rear axle service on vehicles such as the Ford Ranger, Ford Explorer, Dodge Ram 1500, and Chevrolet Blazer, where maintaining clean, leak-free differential operation is essential. If you are replacing a worn pinion seal, WS8835S provides the dimensional accuracy needed for a proper service repair.

What It Helps Address

• Gear oil seepage at the differential pinion
• Contamination from road debris and moisture
• Seal wear that can lead to fluid loss
• Noise or driveline issues caused by low differential lubricant
• Service repairs on rear axle assemblies with matching dimensions

Installation Notes and Tips

Confirm housing bore, shaft diameter, and seal width before installation. Clean the pinion bore and shaft surface thoroughly, and inspect for grooves or damage that could affect sealing. Proper installation depth and alignment are important for leak-free operation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Manufactured with nitrile sealing material, SAE 1008 spring material, and SAE 1070 seal case material to support consistent fit and sealing performance in rear differential service.
