InMotion WS710663 Transfer Case Output Shaft Seal - Rear

Transfer Case Output Shaft Seal Overview

The InMotion WS710663 transfer case output shaft seal is built to maintain a tight barrier at the shaft interface and keep contaminants out of the transfer case. It uses fluoro-elastomer sealing material for durability and consistent sealing performance in demanding driveline service.

Compatible With Jeep Cherokee, Jeep TJ, Jeep Wrangler, and Hummer H1 rear transfer case applications listed below, this seal addresses leakage concerns where the output shaft passes through the housing. The WS710663 is a direct-fit sealing component for specific New Process transfer case applications.

Key Features

• Fluoro-elastomer sealing material for resistance to heat and fluid exposure
• Precision dimensions for a secure fit at the shaft and housing bore
• Designed to help maintain transfer case fluid containment
• Built for rear transfer case output shaft sealing applications
• InMotion WS710663 part number for accurate ordering and replacement

Detailed Description

The WS710663 is a transfer case output shaft seal engineered around specific shaft and bore dimensions, including a 1.177 inside diameter, 2.572 outside diameter, and 2.578 housing bore. Its fluoro-elastomer construction supports reliable sealing where the output shaft exits the transfer case, helping protect internal components from moisture and debris intrusion. This part number, WS710663, is listed for 1997-2001 Jeep Cherokee, 1997-2001 Jeep TJ, 1997-2001 Jeep Wrangler with New Process 231J Transfer Case, and 2002-2004 and 2006 Hummer H1 with New Process 242H Transfer Case.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Transfer case fluid seepage at the output shaft
• Contamination from dirt, water, and road debris
• Wear-related sealing loss around the shaft opening
• Moisture intrusion that can affect internal transfer case components

Installation Notes and Tips

Verify transfer case type before ordering, since fitment varies by New Process 231J and 242H applications. Inspect the shaft surface and housing bore for wear, scoring, or corrosion before installation. Clean the sealing area thoroughly so the new seal seats evenly and maintains proper contact.
