How Often Do You Grease Boat Trailer Bearings?

The frequency with which you should grease your boat trailer bearings depends on a few factors, including the type of trailer, the weight of the load, and the climate you live in. However, as a general rule of thumb, you should grease your boat trailer bearings every 3,000 to 4,000 miles, or annually even if you don’t travel very far.

If you live in a hot or humid climate, you may need to grease your bearings more often, as the heat and moisture can cause the grease to break down more quickly.

Here are the steps on how to grease your boat trailer bearings:

  1. Park your trailer on a level surface and chock the wheels.
  2. Remove the hubcap or wheel cover.
  3. Locate the grease fitting. It is usually a small, cylindrical protrusion with a threaded opening.
  4. Attach a grease gun to the grease fitting.
  5. Pump grease into the bearing until it is full.
  6. Disconnect the grease gun and replace the hubcap or wheel cover.

Here are some tips for greasing your boat trailer bearings:

  • Use a high-quality grease that is designed for wheel bearings.
  • Do not over-grease the bearings, as this can cause them to overheat.
  • Inspect the bearings after greasing to make sure they are properly lubricated.

If you notice any signs of wear or damage to the bearings, such as heat, noise, or vibration, have them repaired or replaced as soon as possible.

Here are some signs that your boat trailer bearings need to be replaced:

  • The bearings are making noise.
  • The bearings are hot to the touch.
  • The bearings are vibrating.
  • The bearings are leaking grease.
  • The bearings are not turning smoothly.

If you notice any of these signs, it is important to have the bearings replaced as soon as possible. Worn or damaged bearings can cause the trailer to become unstable and could lead to a serious accident.
