What It Helps Address

• Premature bearing wear from failed sealing
• Leakage at rear axle wheel-end service points
• Seal replacement needs on Ford F-350 and F-350 Super Duty rear applications

Installation Notes and Tips

Verify bore diameter, seal outside diameter, and seal width before installation. Match the seal to the exact axle position and vehicle configuration, especially on dual rear wheel and rear inner applications. Inspect the hub, spindle, and bearing surfaces for wear or scoring before installing the new seal. The FAG SS3358 part number should be confirmed against the removed seal and vehicle service information.
