Fitment and Application Details

Compatible With 1976-1986 Jeep CJ7, rear inner; 1981-1985 Jeep Scrambler, rear inner; and 1976-1983 Jeep CJ5, rear inner. The SKF 13839 wheel seal is a fitment-specific option for Jeep rear axle service where the seal must match the shaft and housing dimensions exactly. This part number, 13839, is also referenced in service and interchange listings for the same application.

SKF has a long history in seal design, including early integrated shaft seal development and continued refinement of bonding methods and material selection. That background is reflected in the way SKF 13839 is built to meet the demands of lubricant retention and contamination control in driveline service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Seal Can Address

• Gear oil seepage at the rear inner wheel seal area
• Contamination entering the hub or axle sealing zone
• Seal wear from age, heat, and road exposure
• Loss of lubricant retention in rear axle service
• Noisy or rough operation caused by compromised sealing surfaces

Installation Notes and Tips

Verify the shaft diameter, outside diameter, and width before installation to confirm the SKF 13839 matches the axle assembly. Clean the sealing bore and shaft surface thoroughly, and inspect for scoring, corrosion, or wear that could affect seal life. Proper seating and alignment are important for rear inner Jeep CJ5, CJ7, and Scrambler applications.
