Detailed Description

InMotion WS710536 is a differential pinion seal engineered to create a secure barrier at the front outer pinion location. The fluoro-elastomer sealing material is selected for resistance to contamination and fluid seepage, helping protect the internal differential components from debris and moisture. For drivers servicing Cadillac Escalade, Chevrolet Silverado 2500 HD, GMC Yukon, and related GM platforms, this seal supports proper driveline sealing where the pinion enters the differential housing.

This part cross-references common OE-style service applications for the same front outer differential pinion seal position. Use the part number WS710536 to verify the correct seal before installation.

What It Helps Address

• Differential gear oil leaks at the pinion area
• Contamination entering the front outer differential seal surface
• Moisture intrusion around the pinion opening
• Seal wear from age, heat, and driveline use
• Service issues on GM trucks and SUVs with 8.25 in ring gear or AAM axle configurations

Installation Notes and Tips

Confirm the axle configuration, ring gear size, and seal dimensions before installation. Clean the housing bore and pinion shaft sealing surface thoroughly, and inspect for scoring or wear that could affect sealing performance. Proper alignment during installation is important to avoid damaging the fluoro-elastomer lip and to help the seal seat evenly in the housing.
