How to Choose the Best Boat Trailer Bearings, Hubs & Springs
Maintenance and Installation Tips
Regularly inspect bearings for signs of wear, such as pitting or discoloration. Repack bearings with marine-grade grease at least annually, or more often if frequently submerged. Check that hub caps are properly sealed to prevent water intrusion. When replacing springs, ensure you have the correct type and capacity, and that they are installed securely to prevent bouncing or failure. Always follow manufacturer guidelines for torque specifications when reassembling hubs and wheels.
