Best Wheel Bearing Grease for Travel Trailers

Changing the wheel bearing grease on your trailer is a relatively simple task that you can carry out at home provided you have the correct tools and know-how for the job. Maintaining your wheel bearings is essential for travel trailers as they are commonly used seasonally, maybe only a couple of times per year. If it is sitting idle, then condensation can creep into the bearing and allow it to rust. That rust can form scratches which lead to friction, friction equals heat, resulting in bearing failure.

Moisture and heat are the 2 major factors that wheel bearing grease protects against. Keeping the wheel bearings lubricated year-round will enable your travel trailer to be protected and prepared for use at short notice.

What exactly is wheel bearing grease?

Grease is basically a heavy oil (lubricant) that is combined with enough ‘soapy’ chemicals (thickener) to give it a thick, gluey consistency, strong enough to stay in place as the balls in the bearing spin. Each ball must remain consistently lubricated under a wide range of conditions, high temperature, great load-bearing, speed, water, and climate. The friction that works brakes creates an incredible amount of heat. Wheel bearing grease needs to be able to tolerate this and remain intact to protect your trailer’s components.

Types of wheel bearing grease (thickeners)

Aluminum complex

A high dropping point of approximately 500°F and excellent water resistance are its main qualities. Additives that improve performance such as oxidation and rust inhibitors, mix well.

Calcium grease

Has good water tolerance but will not withstand temperatures above 150°F.Usually, these are less expensive than other varieties.

Lithium stearate

Pumpability! Continues to protect the more it gets worked. Resists water well and doesn’t break down. Has a dropping point of 350°F and a soft, smooth texture.

Lithium complex

Very similar to above but it is a newer product and has grown with necessity. It has a higher dropping point of around 500°F and has the properties to prolong the bearing’s life. White lithium is ideal for metal-to-metal and metal-to-plastic applications. It keeps surfaces friction-free and withstands moisture and extreme heat.

Polyurea grease

This one doesn’t use the traditional soap to thicken it. It has a dropping point of 470°F, brilliant water resistance, and offers superb life extension to your bearings under very high temperatures. Again, pumpability is a great quality it posses.


When it becomes time to grease your travel trailer’s wheel bearings, it is always wise to completely clean them before adding a new layer of grease. Always assume that you don’t know which type the previous layer was, as different greases aren’t compatible with each other. The layers might separate causing your bearings not to have protection, they could fail and your trailer could break down.

No one wants to be sat on the edge of the highway when they were on their way for a fishing trip! To clean; soak them in a solvent, paint thinner, kerosene or turpentine, and use a Q-tip and rags to remove as much old grease as possible. Dry them as thoroughly as possible, being careful not to knock any balls out of place. When they’re dry, a quick spray of brake cleaner will remove any dust, and then they are ready to be packed with grease and placed back in the same position from where they came.


I have only basic mechanical knowledge; will I be able to carry out this job?

We don’t see any reason why not, arm yourself with the service manual for your vehicle and maybe a YouTube video and you’re good to go. It is a relatively simple job. If you’re unsure, it is always wise to call in the experts.

Will I need any specialist tools to apply the grease?

If you own a bearing packer then the job will definitely be easier, but it is not essential. Just high-temperature grease, rags, a wheel jack, a torque wrench, and a hammer are all you will need. Safety goggles are always a wise idea, using a hammer can often result in tiny chips of metal flying through the air.

How often should I change the wheel-bearing grease on my trailer?

It’s worth doing once every season, but at least every 10,000 miles. Smaller wheels spin faster and put greater pressure on bearings so they need lubricating even more often.

Should you mix 2 different types of wheel-bearing grease?

Absolutely not. Each type may be incompatible with the next and have adverse effects on your vehicle. The remaining grease should always be cleaned out before any more are added. See above for how to do it.

If a product is labeled as Marine grease, is it just for boats?

No, marine grease just means it is ideally suited for trailers and vehicles that spend a lot of time around the water. We know that water is one of the biggest enemies of metal car components, when it’s saltwater, well, the problem just gets worse. Marine greases are of high quality and often more expensive.

They are lithium-based which means they won’t degrade when they come into contact with water. They also have extreme pressure additives enabling them to withstand high friction when performing several operations in different temperatures. They are not only suited to marine use, but they are also often the best wheel-bearing grease for travel trailers. The grease is very versatile and can be used in lots of automotive and household situations, as well as around a marina.

What does NLGI #2 mean?

It’s a measurement of grease, it just tells you the ‘hardness’ or viscosity of it. The National Lubricating Grease Institute gives each grease a grade, all of the ones featured in our review are Number 2. The numbers range from 0 to 6, with 0 being almost liquid and 6 is the consistency of hard cheese.

What does ‘dropping point’ mean?

It is the temperature at which the lubricating grease turns from a semi-solid into a liquid form. You can use this test to tell what type of thickening soap was used in its manufacture. Wheel bearing grease needs to be able to tolerate very high temperatures.

What is moly-grease?

Molybdenum disulfide can be added to general greases to provide higher-pressure protection and low-friction properties. It is robust and will help protect and extend the service life of your disc pad wheel bearings.

The Bottom Line

Hopefully, our guide will have given you a greater understanding of the different types of grease and helped you to decide which is the best wheel-bearing grease for travel trailers. Once you have decided whether you prefer to use an applicator gun or do the job by hand, get the necessary equipment, rags, eye protectors, etc. Don’t forget a pair of gloves too, this grease is, well, greasy! It gets everywhere! Remember, that these are very versatile products, whilst they will do a great job of protecting your car’s components, they can also be used for so many other things. Garden tools, firearms, motorcycles, and snowmobiles are just a few of the items that it’s worth keeping a tub of grease handy for. You might even be able to use it to stop the kid’s trampoline from squeaking!

  1. Valvoline grease is the greasiest of the greases. I have greased some things with this grease. Those things have been greased and will continue to have been greased. The container leaked a little though during shipment and some grease was on things that did not necessarily need to be greased. I cleaned it up though. No worries. Grease.
