Traveling isn’t all fun and games; you have to do some maintenance, too. When it comes to travel trailers, we wanted to look at one specific aspect of routine maintenance: greasing the wheel bearings.

Lubricating the wheel bearings with a wheel bearing grease helps to improve performance and maintain stability of the wheels. This is important because the last thing you want when you’re traveling is to have problems with your trailer’s wheels. That could mean a lot of time that could be spent sightseeing has to be spent trying to get your wheels fixed, not to mention the cost.

What Does Wheel Bearing Grease Do?

Wheel bearings are a vital component in attaching and rotating your vehicle’s wheels. In order to maintain their structural integrity and keep passengers safe, it’s necessary to keep them lubricated and protected. To do this, you apply wheel bearing grease.

Wheel bearing grease reduces friction, which can cause overheating and even failure of the wheel bearings. It also eases rotation in the bearings and protects the metal from corrosion and wear. It quite literally greases your wheels so your vehicle and trailer can move.

Types of Wheel Bearing Grease

There are several types of wheel bearing grease to choose from, depending on the applications you need it for. These types include disc and drum, molybdenum, ion-based and marine wheel bearing grease.

Disc and Drum

Disc and drum bearing grease is meant for high pressure and high temperature applications. It is often used on disk and drum brakes, but can also be used on other equipment. It is water resistant, so it protects against water damage and rust.

Molybdenum (Moly EP)

Commonly known as Moly EP, this type of grease is made of molybdenum disulfide. This compound is highly corrosion resistant with a high drop, or melting, point. The EP stands for extreme pressure, indicating that the grease holds in extreme pressure applications. It is often used with ball and U-joints.

Ion-Based

You may have heard the term “lithium ion” when referring to batteries. Ion-based grease is a lithium or calcium based grease. The benefits of ion-based grease depends on which element it uses, but all versions are water resistant with varying heat tolerances.

Marine

Marine wheel grease is resistant to water and salt. It is made for use in ocean environments, but is also useful for equipment and vehicles that operate near the sea or in cold climates. Marine grease is a good choice for vehicles that have to contend with snow and deicing salt frequently.

Now that we have the basics covered, let’s review some greases.

In this article, we’ve compiled a list of some of the best wheel bearing greases of 2021. We will compare each of them and determine which one stands out as the top wheel bearing grease. Read on to find out which grease is the best.

Conclusion

There are a lot of excellent grease options out there, with a ton of different applications. With travel trailers in mind, our pick for best wheel-bearing grease has to be the Royal Purple Ultra-Performance Grease.

This grease is multipurpose and designed to lengthen the lifespan of bearings and increase their reliability. That’s important when you’re on the road a lot. It even has cooling properties, although with such a high drop and flash point it doesn’t need to cool down to function well.

The other greases on our list simply can’t compete as they are more limited than this grease. The only option to come close would be the Lucas X-Tra Heavy Duty grease, but it’s still not as versatile as the Royal Purple. 

Royal Purple’s products are also a distinctive purple color, making them stand out among their competitors. This also helps when applying the grease, as it has good visibility while not being ostentatious. 

The one downside compared to other greases is just that it’s synthetic grease. This fact doesn’t affect its longevity or applicability, but it can make it more difficult and time-consuming to use. Synthetic grease will liquefy non-synthetic grease, so it will need to be reapplied if there is non-synthetic grease left on the surface before the first application.

All things considered, Royal Purple has our vote for best wheel-bearing grease for travel trailers in 2021. It is the most versatile as a multipurpose grease and has the best temperature ratings compared to the other greases on our list.
