01Why is greasing boat trailer hubs important?

  • Boat trailer hubs contain bearings that allow the wheels to rotate smoothly.
  • Greasing the hubs creates a protective barrier between the bearings and the elements, preventing water and dirt from entering.
  • Proper lubrication reduces friction and heat, preventing premature wear and damage to the bearings.
  • Regular greasing extends the lifespan of the bearings and ensures safe and reliable towing.
  • Neglecting to grease the hubs can lead to expensive repairs and potentially dangerous situations on the road.

02Tools and materials needed

  • Grease gun
  • Marine-grade wheel bearing grease
  • Rags
  • Latex gloves
  • Disposable hand wipes
  • Jack and jack stands

03Step-by-step guide to greasing boat trailer hubs

  • Park your boat trailer on a flat, level surface and engage the parking brake.
  • Use a jack to lift the trailer off the ground, ensuring it is supported securely by jack stands.
  • Locate the grease fitting on each hub. The grease fitting is typically a small metal nipple.
  • Attach the grease gun to the grease fitting and pump the handle until you feel resistance.
  • Slowly pump grease into the hub while rotating the wheel. Continue pumping until fresh grease starts to come out from the hub.
  • Repeat this process for each hub on the trailer.
  • Once all the hubs are greased, wipe off any excess grease with a rag.
  • Lower the trailer back down using the jack and remove the jack stands.
  • Test the wheels to ensure they rotate smoothly and without any unusual noise or resistance.

Conclusion

Regularly greasing your boat trailer hubs is an essential part of trailer maintenance. By following these steps, you can ensure smooth and safe towing, prolong the lifespan of your trailer's bearings, and avoid costly repairs. Remember to perform this maintenance task at least once a year or more frequently if you frequently use your boat trailer in wet or dusty conditions.
