InMotion WS7687S Wheel Seal - Rear Inner

Rear Inner Differential Pinion Seal for Jeep Axles

The InMotion WS7687S is a nitrile wheel seal built to create a tight barrier at the differential pinion area. It helps keep gear oil in place while blocking dirt, water, and road debris from reaching sensitive internal components.

Use this seal when servicing a Jeep CJ5, CJ7, Scrambler, or Grand Wagoneer rear inner axle application that calls for a precise sealing fit. The WS7687S is sized for the specified shaft and housing dimensions to support reliable sealing performance.

Detailed Description

InMotion WS7687S is engineered as a differential pinion seal for driveline service where contamination control and leak prevention matter.
