Replacing your Boat Trailer Bearings (Step by Step Instructions)

How Often Should Bearings Be Replaced on a Boat Trailer?

Bearing maintenance is one of the most important aspects of owning a boat trailer. Neglecting to properly maintain your bearings can result in serious damage to your trailer and even your tow vehicle. Bearing failure is often sudden and catastrophic, resulting in loss of control of the trailer and possibly an accident.

The good news is that bearing maintenance is relatively simple and inexpensive, especially when compared to the cost of repairs or replacing damaged equipment. The key is to inspect and service your bearings on a regular basis, before they have a chance to fail. How often should you replace your boat trailer bearings?

That depends on a number of factors, including how often you use your trailer, what kind of terrain you typically travel over, and whether you keep your trailer stored indoors or outdoors. In general, though, most experts recommend replacing boat trailer bearings every two years or so. If you use your boat trailer frequently or travel over rough roads frequently, you may need to replace your bearings more often than that.

And if you store your boat trailer outdoors in harsh weather conditions (salt water environment), you should inspect and service your bearings more frequently as well. The best way to determine how often to replace your boat trailer bearings is to have them inspected by a qualified technician at least once per year. They will be able to check for signs of wear and tear and advise you on when it’s time for new bearings.

How Do I Know If My Boat Trailer Bearings are Bad?

If your boat trailer bearings are bad, there are a few things you will notice. First, your trailer will likely make noise when you tow it. This noise will be a grinding or squealing sound and will be coming from the area of the bearings.

Secondly, your trailer may feel like it is shaking or vibrating more than usual while you are driving. This is caused by the bearings not being able to rotate smoothly. Finally, if you look at your bearings, they may appear to be worn down or damaged.

If any of these symptoms are present, then it is time to replace your boat trailer bearings.

How Much Does It Cost to Replace Wheel Bearings on a Boat Trailer?

If you’re like most boat owners, you probably don’t give your boat trailer’s wheel bearings a lot of thought – that is until they start making noise or cause your trailer to handle oddly. Then, all of the sudden, those little round metal objects become very important! While replacing wheel bearings on a boat trailer isn’t a complicated task, it is one that requires some care and attention to detail.

This is especially true if you’ve never done it before. The good news is that we’re here to help. In this article, we’ll walk you through everything you need to know about replacing the wheel bearings on your boat trailer, including what tools you’ll need and how much it should cost.

Assuming that your boat trailer has standard 4-lug or 5-lug hubs (most do), the first thing you’ll need to do is remove the hub cap or dust cover. Once this is off, use a wrench or socket to loosen the axle nut. You may need an impact gun or air compressor to get this nut loosened if it’s been on there for awhile.

With the axle nut removed, gently pull the hub assembly off of the spindle. Next, using a hammer and punch (or screwdriver), drive out the old inner bearing race from the hub. Be careful not to damage the spindle while doing this.

Now simply slide off the old outer bearing race and then remove any grease seals that may be in place. At this point, take a look at all of the parts – including the races, bearings and seals – and make sure there is no damage or excessive wear present. If everything looks good, you can go ahead and clean up all of the parts with solvent before proceeding.

Now it’s time to install new grease seals in both sides of the hub assembly using a seal driver tool (or something similar). Once these are in place, pack new high-temperature bearing grease into each side of the hub until it starts overflowing out slightly when compressed – about 1/2″to 3/4″ full is usually plenty .

Service Boat Trailer Bearings

If you’re like most boat owners, you probably don’t think much about your trailer bearings – that is until they fail. Then, it’s suddenly a very big deal. Fortunately, there are some simple things you can do to keep your bearings in good shape and avoid a catastrophic failure on the road.

The first step is to understand what Trailer Bearings are and how they work. Trailer Bearings are located at the hub of each wheel and allow the wheel to rotate freely. The bearings consist of an inner race (the cone), an outer race (the cup), and rolling elements (balls or rollers).

As the name implies, ball bearings use balls as their rolling elements while roller bearings use cylindrical rollers. Most trailers use tapered roller bearings because they can support both radial and thrust loads – something that is important when towing a heavy load behind your vehicle. That said, there are also sealed versions of both ball and roller bearings that don’t require regular maintenance other than making sure they’re clean and greased before hitting the road.

The second step in taking care of your trailer bearings is to make sure they’re properly greased before each trip. This involves removing the dust cap from the bearing hub, cleaning out any old grease/dirt, adding fresh grease until it starts squishing out of the seals, then replacing the dust cap. It’s important not to over-grease as this can cause excessive heat build-up leading to premature failure.

A good rule of thumb is to add enough grease so that it just starts coming out of the seals when you spin the wheel by hand – no more, no less! If you notice any strange sounds or vibration coming from your trailer wheels while driving, it’s likely due to a problem with the bearings. Pull over as soon as possible and investigate further – don’t risk damage by continuing to tow with failing bearings!

Once you’ve confirmed there is an issue, replace the affected bearing(s) with new ones as soon as possible – don’t try to “make do” with old/worn-out parts. Your local auto parts store should have everything you need for this repair job including replacement bearing kits complete with races, seals, grease etc..

Trailer Wheel Bearing Diagram

If you’re having trouble with your trailer’s wheel bearings, you’re not alone. Many trailer owners have difficulty keeping their bearings in good working order, and it’s no wonder why. Wheel bearings are one of the most important parts of any vehicle, but they’re also one of the most neglected.

Most people don’t even know what wheel bearings are, let alone how to maintain them. That’s where this blog post comes in. We’ll give you a crash course in wheel bearings and show you a few easy tips for keeping them in tip-top shape.

Wheel bearings are located between the wheels and the axles of your trailer. They allow the wheels to rotate smoothly and without friction. When they become worn or damaged, they can cause all sorts of problems including premature tire wear, increased fuel consumption, and decreased handling performance.

There are two main types of wheel bearings: tapered roller bearings and ball bearings. Tapered roller bearings are more common on trailers because they can handle higher loads than ball bearings. However, both types require regular maintenance to stay in good working order.

The best way to prevent problems with your trailer’s wheel bearings is to inspect them regularly and keep them clean and lubricated. If you notice any damage or excessive wear, replace the bearing immediately. It’s also a good idea to check the condition of your wheels and tires while you’re at it since they play a big role in how well your trailer handles on the road.


Boat trailer bearings are an essential part of towing your boat. Over time, however, they can become worn down and need to be replaced. This process is not as difficult as it may seem, and with a few simple steps you can have your bearings replaced in no time.

To start, you will need to gather the necessary tools including a jack, jack stands, a wrench set, and replacement bearings. You will also need some grease for the new bearings. Once you have everything you need, begin by jacking up the trailer and removing the wheels.

Next, use the wrench set to remove the old bearings from the hub assembly. Be sure to keep track of which bearing goes on which side so that you can properly install the new ones. After the old bearings are removed, clean out the hub assembly before adding fresh grease and installing the new bearings.

Once everything is back in place, reattach the wheels and lower the trailer back down. With these easy steps, you’ll have your boat trailer’s bearings replaced in no time!
