🔧 HILLTOP MAINTENANCE TIP: 10 MINUTES NOW COULD SAVE YOU A BIG HEADACHE LATER!
You keep your boat in shape, but don't forget about the trailer carrying it down the highway! 👀
Trailer bearings allow your wheels to spin smoothly. If they lose lubrication or become contaminated with water, they can overheat and fail, potentially damaging your hub, axle, and tire.
Here's what to check if your trailer has a grease fitting system with a rubber access plug and a rear grease-relief port:
🛠️ 1. Remove the rubber plug.
Use a screwdriver carefully to remove the plug and expose the grease fitting.
🛠️ 2. Check the system before adding grease.
Make sure you know which bearing system you have and follow the manufacturer's instructions. Use the specified marine-grade wheel-bearing grease.
🛠️ 3. Add grease slowly.
Attach your grease gun and pump slowly while following the hub manufacturer's procedure. On systems designed to purge old grease through a rear relief port, watch for old grease to exit the port. Stop when fresh grease appears, or as the manufacturer directs. Don't force grease into a sealed hub or overfill a system that isn't designed to purge.
🛠️ 4. Inspect and replace the plug.
Clean away excess grease, check the rubber plug for cracks or damage, and replace it if needed.
🛠️ 5. Look for warning signs.
Grease leaking around the hub, unusual wheel play, grinding noises, or excessive heat can indicate a problem. Adding grease won't fix worn or damaged bearings.
⚠️ One more thing: Greasing your bearings is not a substitute for periodic inspection. Follow your trailer manufacturer's service schedule, especially if your boat spends a lot of time in the water.
