Timken 40286 Wheel Seal for Jeep J20

Timken 40286 is a wheel seal built for rear inner service on 1985-1988 Jeep J20 models. It is engineered to retain lubricant at the axle while helping block dirt, moisture, and other contaminants from entering the sealing area.

Key Features

  • Precision sealing design for lubricant retention
  • Reinforced outer case to resist installation damage and improve durability
  • Ribbed rubber inner diameter to seal minor spindle imperfections and promote spindle seating
  • Internal contamination exclusion system to help keep debris out of the seal area
  • Vent holes that allow lubricant flow around the seal lip to reduce heat build-up

Detailed Description

Timken 40286 is a rear inner wheel seal for Jeep J20 trucks from 1985 through 1988. This seal is designed for applications using the Dana/Spicer 44 axle differential pinion race noted in the fitment data, making it a direct-match service part for axle sealing maintenance. Timken 40286 helps maintain proper lubrication at the wheel end while supporting clean, stable operation in demanding driveline conditions. This part cross-references Continental 40286 for the same application.

What It Helps Address

  • Gear oil or grease leakage at the wheel end
  • Contamination entering the seal area
  • Seal damage during installation
  • Minor spindle surface irregularities affecting seal contact
  • Heat build-up around the seal lip

Installation Notes and Tips

Install Timken 40286 on the rear inner position only for the listed Jeep J20 applications. Inspect the spindle, hub, and sealing surface before installation, and verify the Dana/Spicer 44 axle differential pinion race note matches the vehicle configuration. Clean the bore and seating surfaces thoroughly so the seal can seat evenly and maintain proper contact.

Quality Assurance

Timken designs its oil and grease seals with precision sealing features, reinforced construction, and contamination control to support reliable driveline service. Part number 40286 is built to the same application focus as the listed interchange reference and fitment data.
