Product Details

The SKF Scotseal Plus XL line is engineered for extended service life in rear wheel applications. This seal uses hydrogenated nitrile butadiene rubber to handle elevated temperatures and frequent braking cycles, while helping keep lubricant in place and road contaminants out. For fleets and service shops working on axle and wheel-end repairs, 38776XT is a practical choice for maintaining reliable sealing performance on vehicles that depend on durable wheel seals. It is a strong match for heavy-duty driveline and axle service, including applications such as Freightliner and International truck wheel-end maintenance where rear wheel seal service is required.

This part cross-references Gates 38776 for the same application.

What It Helps Address

  • Wheel-end lubricant leakage
  • Contamination from dirt, water, and road debris
  • Heat-related seal wear from repeated braking
  • Seal instability on the shaft
  • Premature wheel seal replacement in demanding service

Installation Notes and Tips

Inspect the shaft, hub, and sealing surface before installation. Clean all mating surfaces thoroughly and verify the shaft diameter and seal dimensions match the application: 3.875 in shaft diameter, 5.704 in outside diameter, and 0.892 in width. Install carefully to avoid damaging the sealing lip or distorting the seal body. Confirm the rear wheel position and axle specification before service on Freightliner, International, or other heavy-duty truck applications.
