Timken 11S38750T Wheel Seal - Rear or Rear Inner

Timken Wheel Seal for Driveline Service

The Timken 11S38750T wheel seal is built for hub and axle sealing applications where heat control, contaminant exclusion, and bore retention matter. Its oversized metal outer diameter helps resist spinning or walking out of the hub bore, while the S-nitrile sealing material supports reliable performance across a wide temperature range.

For technicians servicing wheel seal replacement on axle and hub assemblies, this Timken wheel seal provides a direct-fit sealing solution for worn or damaged sealing surfaces. It is a practical choice for driveline and axle repair on vehicles such as Honda Civic and Toyota Corolla applications where precise sealing performance is critical.

Detailed Description

Timken 11S38750T is a wheel seal engineered for driveline and axle sealing service where consistent lubricant retention and contamination control are required. The metal outer diameter is designed to stay seated in the hub bore, and the sealing design uses multiple contact barriers to help reduce lip wear in demanding operating conditions. The seal’s construction also supports heat dissipation, which is important in hub assemblies exposed to sustained road and brake heat.

This wheel seal is a fitment-focused replacement for applications that call for a 5.706-inch outside diameter and 3.875-inch shaft diameter. It is commonly searched as a Timken wheel seal for Honda Civic wheel seal replacement and Toyota Corolla axle seal service, and the 11S38750T part number is often used when matching OE-style dimensions during hub maintenance.

This part cross-references SKF 38747 for the same application.

What It Helps Address

• Gear oil or grease leakage at the wheel end
• Contamination entering the hub or axle seal area
• Seal lip wear from heat and debris exposure
• Seal movement in the hub bore
• Damage around worn axle shoulders

Installation Notes and Tips

Inspect the hub bore, axle shoulder, and sealing surface before installation. Clean away corrosion, old seal material, and lubricant residue so the new seal seats evenly. Verify the dimensions against the original seal and confirm the housing bore, shaft diameter, and width before pressing the seal into place.

For best results, install the seal squarely and avoid nicking the sealing lip during assembly. Use proper service procedures for the hub or axle being repaired, and confirm lubricant level and bearing condition after installation.

Quality Assurance

Timken is a recognized name in driveline and axle sealing components, and this wheel seal is built with corrosion-resistant spacer features and a reinforced outer wall for demanding service conditions. Part number 11S38750T is specified with precise dimensional data to support accurate replacement selection.
