• Seal wear that leads to axle-end contamination
• Front axle service on Ford F-250 and Ford F-350 trucks

Installation Notes and Tips

Verify the axle type, position, and dimensions before installation, especially on applications that specify Spicer 50 or Spicer 60 axles or V-ring type notes. Inspect the bore, shaft surface, and surrounding hub components for wear or damage before fitting the new seal. Clean the sealing surfaces thoroughly and confirm the seal seats squarely to avoid premature leakage.
