What It Helps Address

• Grease loss at the wheel end
• Dirt and dust intrusion into bearing areas
• Moisture contamination around axle seals
• Premature wear from compromised wheel-end sealing
• Seal replacement needs on Spicer 50 and 60 axle applications

Installation Notes and Tips

Verify bore diameter, seal outside diameter, and seal width before installation. Confirm axle type, position, and vehicle class against the application listing, since wheel seal requirements vary by setup. Inspect the hub, spindle, and bearing surfaces for wear or damage before installing the new seal.
