Best Wheel Bearing Grease for Travel Trailers Buying guide
Selecting the right wheel bearing grease involves a few factors, and it is better to know rather than purchase the wrong one.
Grease comprises lubricants and thickeners (calcium sulfonate), and these two ingredients mix to a certain level of viscosity. (Read Propane Refrigerator RV)
Viscosity will be measured from zero to six, and near-zero the grease is runny while six is hard. Wheel bearing greases need ratings of two, as they offer great protection while soft to use.
Grease compatibility is vital as you need to be sure you have one type and the thickness is the same. Ideally, you’d remove old grease and fill it with new. You can also use enough force to push the old grease out.
Any wheel-bearing greases need to deliver water-resistant functions, and they can protect your rig against water or moisture issues.
Should you feel, you may suffer, you can opt to use marine wheel bearing greases rather than regular road vehicle grease.
Dealing with High Temperatures
Even if you are in the depths of winter, your wheel bearing will operate at extremely high temperatures as you travel. You should find a rating of any grease you purchase. A grease that operates outside its rating will stop working. (Learn Paint RV Exterior)
RV wheels suffer from extreme pressure when traveling. Thus, any grease you use needs to deal with high pressures. Like the temps, grease can have a max pressure operating limit. Moly EP greases tend to be the best to deal with high pressure.
Types of Grease
You may ask, what type of grease for trailer wheel bearings is there? You can find many, yet not all-wheel bearing grease types that are suitable for RVs.
- Multi-Purpose Grease: Multi-purpose grease is the most affordable, though not suitable for wheel bearings.
- Moly EP Grease: Moly EP greases are made for lubricating high-pressure areas. They are ideal for heavy loads and farming equipment as it contains molybdenum disulfide.
- White Lithium Grease: All white lithium grease types contain Zinc. You’ll find this an alternative to multi-purpose grease that gets dirty.
- Disc/Drum Wheel Bearing Grease: Here, you have the first made specifically for wheel bearings. Disc/drum wheel bearing grease is useful as it deals with high heat from RV wheel bearings. This grease has water-resistant abilities and can be used as a multi-purpose option.
- LMX Red: LMX Red is a premium grease for high pressure, water, and temperature fluctuations. LMX red grease offers top-tier protection for trailer tires and lots of other equipment.
- Marine Grease: Marine wheel bearing grease is made to work on equipment, which intends to contact water. It provides water resistance, and wheel bearings won’t suffer water damage.
