Sta-Lube has a loyal following of RV and travel trailer users. Most online reviews place it in the top 3 for best wheel bearing grease, and it isn’t difficult to figure out why. Sta-Lube SL3121 has everything RVers want in a wheel bearing grease: adhesion, viscosity, and ease of application More importantly, SL3121 possesses excellent heat dissipation regardless of exterior conditions, making it ideal for RV travel trailer owners who like to roam. Sta-Lube is also marine-rated, so keeping moisture and corrosion at bay is easy. Moreover, its unique composition means it has the longevity to keep you on the road without needing to reapply grease on the go.

Sta-Lube SL3121 isn’t just for wheel bearings either. It works great on steering quadrants, winches and many other RV components that need grease for regular maintenance. Even if it’s not your first choice for wheel bearing grease, it’s a good idea to keep a tub of Sta-Lube around in your RV toolkit in case you run into trouble on the road.

There is some important feedback I’d like to share about Sta-Lube that should factor into a buying decision: some users have commented online that the grease has a tendency to leak even when applied in small amounts. Others have stated it is a bit thin for some lubricating purposes, and needs regular reapplication. My advice is you should still grab a tub the next time you pick up maintenance supplies and experience SL3121 for yourself. This stuff really does not disappoint.

An all around multi-purpose performer, Royal Purple 01312 has a reputation for delivering excellent reliability, longevity and performance for travel trailer wheel bearings. This grease keeps every surface quiet, cool and smooth. The synthetic composition also offers better water resistance and corrosion protection than conventional wheel bearing grease.

What I like best about this particular grease (in addition to the performance) is the easy-to-use cartridge kit. You can operate and apply the grease cartridge one-handed with the included application kit, or you can drop it into your own suction loaded grease gun and get to work. The bright purple color also makes it easier to keep track of whether you’ve applied sufficient grease, taking the guesswork out of maintenance.

There are a few drawbacks to the Royal Purple 01312 Ultra-Performance Grease. First of all, it’s a bit pricer due to its synthetic composition. It performs extremely well, but you should expect to pay more for that higher performance level. Additionally, some users have commented that oils in the 01312 tend to separate quickly, leading to inconsistent results and occasionally to more frequent applications. All in all, it’s a great wheel bearing grease that should give you the performance you need to keep your travel trailer or 5th wheel on the road longer and with less wear.

  • PROS/CONS OVERVIEW

Pros

  • Easier and more pleasant to apply
  • Bright color is more visible when greasing bearings
  • Works well for many types of recreational vehicle wheel bearings

Cons

  • More costly than similar synthetic wheel bearing grease in its class
  • Oils have been known to separate quickly, requiring reapplication

If you’re looking for a more budget friendly performance wheel bearing grease, the Valvoline Full Synthetic Grease VV985 should be a good fit for you. The VV985 formula is fortified with molybdenum for superior film strength and load resistance even after hundreds of hours of wear. Better still, it’s also high temperature resistant and water repellent, making it easy to ride safely even in extreme weather conditions.

I like this wheel bearing grease as a budget option thanks to the addition of moly-fortification. Moly-grease provides some of the best adhesion you can get, and once you’ve got moly-grease on a moving part it takes some serious detergent to get it back out again. Valvoline’s VV985 also works well keeping other moving parts and joints functioning efficiently too, so it’s not a bad grease cartridge to keep in your RV emergency bag should something go wrong with an axle joint. tow hitch or wheel bearing on the road.

For me, the big drawback for this wheel bearing grease has to be the color. It sounds silly, but brightly colored bearing grease makes proper application so much easier. If the new grease doesn’t contrast enough with the old grease, it’s difficult to tell if you’ve fully exchanged the existing grease. It’s probably a minor issue for most people, but it’s definitely my first choice for this reason. Finally, some users have complained of occasional liquefaction even at temperatures under 100 degrees Fahrenheit. Leaking oils from bearing grease not only affect proper lubrication, but they can also be an ignition hazard under the wrong circumstances. It’s a rarity by all accounts, but still an important consideration.

  • PROS/CONS OVERVIEW

Pros

  • Great load bearing performance
  • Ready for instant use
  • Works for many vehicles and applications.

Cons

  • Know to liquefy at low temperature
  • Known to result in oil leakage

Definitely a fan favorite of veteran RVers, Lucas 10301 X-Tra Heavy Duty Grease is the go to wheel bearing grease for full-time and casual RV owners. It has excellent temperature stability in all climates, and its essentially waterproof thanks to its unique blend of additives.

What I like best about Lucas 10301 is how much time it adds to the maintenance cycle for RV wheel bearings. Thanks to its long lifespan and temperature stability, you will rarely find yourself adding fresh grease. Best of all, even when it does come time to grease your wheel bearings, the bright green color makes it easy to verify you’ve  done a thorough job.

Conversely, I will say that I wish their packaging was more durable. Resealing a cartridge is nigh impossible, so you should stick to buying a cartridge only if you plan to use all of it. If you aren’t especially careful, you can crack the cartridge wall or cap when installing it in your grease gun, too. It’s great wheel bearing grease, just be sure you know what you’re getting into before you buy some.

  • PROS/CONS OVERVIEW

Pros

  • Mess-free application
  • Lasts four times longer compared to other brands
  • Superior stability at all temperatures.

Cons

  • Packaging is poor quality, making it difficult to store and reuse
  • ​Some users commented their cartridges arrived damaged or unusable with their grease gun

Features

  • Superior corrosion and water protection

Long considered the greatest of all time for greasing wheel bearings on marine travel trailers, Plews & Edelmann Lubrimatic 11404 is still the first choice for many RV owners and boating enthusiasts. Not only does it offer the best corrosion and moisture protection available, but it also lasts longer than almost any other wheel bearing grease on the market.

What I like best about Lubrimatic 11404 is the anti-caking formulation. Over time many wheel bearing greases start to coagulate and thicken up with debris and dirt. With the Plews & Edelmann formula, your grease stays smooth and you can go much longer between maintenance cycles for your wheel bearings. Less maintenance is always good in my book.

I think it’s also important to note though that Lubrimatic does not store well, and leftover grease is a pain to clean up if it leaks, spills or gets left behind unattended. It’s a great product for the money, but probably not my first choice for inexperienced RV maintenance techs. Unless your travel trailer spends most of its time outside a garage or you pull a boat to the lake every weekend, you may want to choose something else.

  • PROS/CONS OVERVIEW

Pros

  • Works for many lubricant applications
  • Exceptional corrosion protection
  • Super-stable at both extreme high and low temperature ranges.

Cons

  • Delivery service and online ordering does not meet expectations
  • ​Leftovers and cleanup can be a serious chore

BUYER'S GUIDE

What is the best grease for trailer wheel bearings?

I like the Sta-Lube SL3121 best for travel trailers. It’s got excellent water resistance, protects well against corrosion, and its very easy to apply and clean up. 

How often should you grease wheel bearings on a travel trailer?

It depends on the type of grease and what additives are part of its formula. Some wheel bearing grease can last for 6 months to a year even with heavy driving, while others need to be replaced or replenished every month.  The smart choice here is to choose a wheel bearing grease that’s got a great reputation for longevity, then see how long it lasts.

How do I grease my travel trailer bearings?

Most people have a suction-based grease gun in their tool kit for greasing wheel bearings. They make one-use grease kits with pre-fitted nozzles, but they are not as easy to use as a standard grease gun. Most ball joints that need regular lubrication have a port on one side for applying fresh grease. Plug the grease gun or nozzle into the slot and squeeze until you have added the manufacturer’ recommended volume of grease.

How much grease does a bearing need?

The amount depends on the type of bearing or joining you are greasing. Generally, the general rule is one shot of grease from a standard grease gun per inch of shaft diameter.

What happens if you over grease a bearing?

The bearing will begin churning the grease, spiking its temperature and causing it to eventually liquefy and drain out of the bearing.

What is the ideal dropping point for wheel bearing grease?

Look for grease with a dropping point between 500 and 572 degrees Fahrenheit. That should be more than enough to maintain proper lubrication even under extreme conditions.

CONCLUSION

My top choice for the best wheel bearing grease for travel trailers is definitely the Sta-Lube SL3121. It’s got great water resistance, excellent stability across a wide temperature range and it helps prevent corrosion.

Best of all, the bright blue color makes it easy to see if you have applied sufficient grease to bearings even when you haven’t stripped out old grease first. Grab a tub for yourself and give it a try.

You will find it is useful for many applications beyond keeping your wheel bearings from wearing out too fast.
