Timken 8549S Wheel Seal - Rear or Rear Outer

Timken 8549S Wheel Seal for Jeep Rear Outer

Timken 8549S is a rear outer wheel seal for select Jeep CJ applications. It is built to retain lubricant at the wheel end while helping block dirt, water, and other contaminants from entering the sealing area.

Key Features

• Precision sealing design helps control grease and oil leakage at the wheel end
• Reinforced outer case helps resist installation damage and improve durability
• Ribbed rubber inner diameter seals minor spindle imperfections and supports positive spindle seating
• Internal contamination exclusion system helps keep debris out of the seal area
• Vent holes promote lubricant flow around the seal lip to reduce heat buildup

Detailed Description

This Timken wheel seal is engineered for rear outer positions on 1976-1986 Jeep CJ7, 1981-1985 Jeep Scrambler, and 1976-1983 Jeep CJ5 applications. If you are replacing a leaking Jeep CJ7 rear outer wheel seal or servicing a Jeep CJ5 rear outer axle seal, Timken 8549S provides a direct-fit sealing solution for the specified applications. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

What It Helps Fix

• Gear oil or grease leaking from the wheel end
• Contamination entering the spindle or hub area
• Seal wear caused by heat buildup
• Minor spindle surface imperfections affecting seal contact
• Reduced sealing performance during axle service

Installation Notes and Tips

Verify the rear outer position before installation and inspect the spindle, hub, and seal bore for wear or damage. Clean the sealing surfaces thoroughly and seat the seal evenly to avoid distortion. Confirm the application against the vehicle year, make, model, and position before final assembly.

Quality Assurance

Timken oil and grease seals use precision sealing designs and contamination control features to support reliable wheel-end service. The reinforced case and vented lip design are intended to improve durability and manage operating heat in demanding driveline applications.
