Detailed Description

This InMotion output shaft seal is built around precise dimensions to create a secure barrier at the sealing surface. The polyacrylate construction helps maintain contact at the shaft while resisting contamination from debris and moisture, which is important in transfer case and drivetrain service. If you are replacing a worn seal on a Jeep Wrangler, Jeep Cherokee, or Dodge Ram 1500, WS3173 provides the dimensional fit needed for a proper repair.

This part number, WS3173, also appears in applications across GMC Jimmy, Chevrolet S10, Jeep Grand Cherokee, and Ford Bronco platforms listed in the fitment data.

What It Helps Address

• Oil seepage at the output shaft seal area
• Contamination entering the transfer case or drivetrain housing
• Moisture intrusion around the sealing surface
• Wear-related sealing loss from an aging seal lip
• Service issues caused by incorrect seal dimensions

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation. Clean the sealing surface thoroughly and inspect the shaft for grooves or scoring that could affect seal life. Confirm the exact transfer case or transmission configuration noted in the fitment data, since several vehicles require specific New Process or Tremec applications. For example, WS3173 is listed for certain Jeep Liberty models with the New Process 231J transfer case and select Dodge Ram 2500 and Ram 3500 applications with the New Process 021 PTO.
