Frequently Asked Questions (FAQ)

What is the best wheel bearing grease for boat trailers?

When in doubt, using what the manufacturer recommends is a good rule of thumb. Many trailer manufacturers, however, tend to be very specific about what the manufacturer actually recommends.

However, in most cases what the manufacturer says is just par for the course, and there are several factors about your trailer, needs, and lifestyle that might make one grease a better option than another.

If you are on a budget and are in the market for a wheel bearing grease that is among the cheapest of options, you will want to pay attention to what other greases are made of and make sure it is compatible with the grease you wish to replace.

The cheapest greases are generally a special DIY blend of glue and grease, and you honestly get what you pay for. In some cases, it is worth it to spend an extra few dollars to get a grease that works better than what your trailer said to use.

What type of grease is best for wheel bearings?

Wheel bearings are the most important part of your trailer. They shouldn’t be overlooked. Now that we have that said, if you happen to overlook your wheel bearings and they fail, you are going to be in a world of hurt.

That can be said of any part, whether it’s a bike, a car, a lawnmower, or a boat, but this is especially true of wheel bearings because if they fail, they typically mean the end of the line for whatever they are attached to.

Wheel bearings can be an absolute nightmare to maintain and more often than not require professional help in an auto shop unless you have the right tools and a decent knowledge of how they work.

It might be worth, therefore, taking the time and the extra money to get the right grease, make sure you use it, and make sure you keep your bearings well lubricated.

Is Moly grease good for wheel bearings?

No. Moly grease is not good for wheel bearings. It may seem like a great idea as it is a thick grease and really sticks around, but it is too thick. It has difficulty penetrating the wheel bearing and acts more like lube.

Wheel bearings need to be consistently lubricated. This is why wheel bearings need to be greased. A lubricant needs to be a little runnier than moly grease is.

You want a grease that is thick enough to hold onto, but then has some thinning abilities to allow it to get into those smaller spaces.

That’s why the best grease for wheel bearings is petroleum jelly. It is easy to find at any store and can be applied at home by yourself.

How often should you grease boat trailer wheel bearings?

For those of us lucky enough to own a boat, a boathook trailer is an essential component of getting everything from point A to point B. It is also a very simple device: two hard steel wheels sit on a frame with an axle running through it.

And yet, this relatively simple device is the source of many expensive roadside problems. One of the most common is a busted trailer wheel bearing.

The unfortunate truth is that when it comes to trailer wheel bearings, the saying “better to be safe than sorry” is especially true. Just putting some grease on the bearings is an easy way to prevent a tragedy from occurring and save you the headache of dragging your boat home from the boat ramp.
