Frequently Asked Questions (FAQ)

What are the best trailer bearings?

Trailer bearings are fairly straightforward systems where a wheel rotates on a pair of smooth bearings somewhat like a car. These wheels can be fixed or they can be mounted to the axle.

The problem is that these bearings have a lifespan. They are exposed to the elements, and they will start to deteriorate after a few years of use. Just like any other mechanical component in our lives, they need to be replaced periodically.

Fortunately, most trailer bearings aren’t difficult to replace. Based on your needs, you will need to buy either the wheel bearing itself or the entire assembly. If you are buying for a boat trailer, you will need to buy two bearings.

Most boats will have bearings on both axles, and you will need to replace both. If the bearings look fine, you can clean them up with a cleansing solvent. Otherwise, they should be replaced.

How do I know if my boat trailer bearings are bad?

There are a few telltale signs of bad boat trailer bearings.

When you are first accelerating from a stop, your trailer hitch will bounce back and forth. Or you will hear a thumping noise each time the trailer stops. Both of these are impossible to miss and indicate a problem.

More often than not, though, the struggle to stop your boat trailer will be the first sign that something is wrong. If your boat trailer is rolling along smoothly, then take note of the fact that it was the last thing to work efficiently.

Your low-speed handling will be second to last, and your brake operation will be the last thing to be intermittent.

How often should you change boat trailer wheel bearings?

Trailer wheel bearings are generally a lot easier to check and maintain than tractor or motorcycle bearings. That is not to say they are overly simple, but they are definitely less complex.

The frequency by which you will need to change the bearings on your trailer wheels will often be dictated by how you drive, towing, and your driving habits.

If your trailer is used for towing long distances and over rough roads, the bearings will wear down faster than average. If you are careful about towing distances, the bearings should last a long time, especially if you regularly check them.

What is the best boat trailer wheel bearing grease?

Finding a good wheel bearing grease may seem like a tedious task but it is very necessary if you want to prevent your boat from falling off your trailer, or if you want to keep the bearings in good condition.

Since the bearing assembly keeps everything rolling smoothly, you can avoid unnecessary wear and tear by making sure that everything is in tip-top condition.

With so many different products out there, figuring out the best wheel bearing grease out there is no easy task. The interesting aspect is that each lubricant has different characteristics to it, depending on its purpose.

As a plus, it is best to find the right grease even if the bearing assembly isnʼt yet worn out. The proper sealants are all withstanding a lot of pressure and friction against the bearing rings, and if you donʼt take proper precautions, the lubricant will die and you will have to face bigger problems.

Conclusion

Boat trailer axle bearings have come a long way since they were originally invented. The wheels used to be made of wood, and the bearings were made of metal or rust proof rubber.

Today though, boat trailer axle bearings are computer-enhanced, made from intricate composite materials that provide strength and performance to what used to be plain wooden wheels. But with all these advancements, what makes the best boat trailer bearings for you?
