Detailed Description

InMotion WS714503 is a transfer case input shaft seal engineered to maintain a dependable seal where the input shaft passes through the transfer case housing. The seal’s polyacrylate construction is selected for sealing durability, while the measured dimensions help support proper seating in the housing bore and consistent contact at the shaft diameter. For vehicles that rely on Borg-Warner transfer cases, this seal is a practical service part for restoring sealing integrity in front-position applications.

Common Problems This Seal Can Address

• Transfer case fluid seepage at the input shaft area
• Contamination entering the transfer case through a worn seal
• Moisture intrusion around the shaft-to-housing interface
• Reduced sealing performance from age, heat, or wear
• Service issues on Borg-Warner transfer case applications

Installation Notes and Tips

Inspect the input shaft, housing bore, and surrounding sealing surfaces before installation. Remove any old seal material, clean the bore thoroughly, and verify that the replacement seal matches the application and transfer case type listed for the vehicle. Proper seating depth and even installation pressure help the seal contact the shaft correctly and reduce the chance of leaks after service.
