Understanding these basics of boat trailers parts will also increase your confidence and pleasure while heading to the lake.

Develop a habit of checking your boat trailer like an airline pilot does to his aircraft before taking off. Where do you start? Here is a check list and the pages that follow will go into more detail about each part:

Critical Reminder

Always check your tire tread for unusual wear and tire pressure before each trip for safety and peace of mind. Also keep track of the age of your tires because they can begin to dry rot before the tread is good. Tires are extremely important item among your boat trailer parts.

Boat Trailer Brakes

Once a year you should check your boat trailer brakes to make sure they have enough pad left to work properly.  Many boat trailers will have traditional drum brakes while some will have the added stability of disc brakes.  Most repairs on brakes will be to replace the pads.  In addition, you should routinely check the brake fluid level to make sure you have adequate fluid for the brakes to work properly.  


Boat Trailer Bunks

The best time to check your boat trailer bunks is each time you launch your boat.  An often overlooked item of your boat trailer parts, observe the normally unobservable - look at the trailer without the boat on it.  Look for worn bunks, carpet that is loose or missing, any broken parts or sharp objects like a screw sticking out where it should not be sticking out.  When you find something that needs to be fixed, plan during a fishing outing to rent a slip at a lake and park your boat in that slip and spend the time fixing your boat trailer bunk or replacing your boat trailer carpet. 


Boat Trailer Bearings / Bearing Grease

Before every outing you double check to make sure you have proper lubrication/grease in each wheel bearing. A hot bearing due to too little grease can cause major problems when traveling down the highway and cause the wheel to sieze up, not good! An ounce of prevention is worth a ton of cure. If your bearings have ever run dry of grease, or gotten excessively hot because they have become worn replace them. Several products are available to help prevent this from happening. If you already have your boat and trailer, and have never seen or used these Bearing Buddy products, I urge you to try them. Know the size of your axle/bearing cover because these come in different sizes to match. Click on the Bearing Buddy Link below and pick a set up; or click more on this link to read more about Boat Trailer Bearingsand the proper bearing grease to use.

The Bearing Buddy protectors allow you to see and feel if the right amount of grease remains in and through your bearing.  These bearing covers keep dirt and moisture away from your Bearing Buddy and provide a nice finished off look for your Bearing Buddy. Make sure you buy the right sized diameter units.

Boat Trailer Hubs and Axles

Most repairs of the hub and axle revolve around the bearings.  However if you find you need to replace the whole hub I suggest you pick up a kit that includes the bearings as well.  This is a good one. Inspect your axle, hubs and bearings at least once a year in detail.  More frequently to check on loose nuts, bolts or hangers..
