When you are performing regular maintenance on your trailer, you may be wondering what kind of grease to use to grease your trailer axles. Bearing grease should be replaced every 36,000 miles or 12 months, whichever comes first.
Topping Off Grease
For axles, especially Lippert axles you need grease with a high dropping point (446°F Minimum). Lippert uses Lucas Red N Tacky Grease #2, at the factory. It has a high drop point and is highly rated. You can use this same grease for any of the grease fittings on the trailer. This grease isn't recommended if you are going to be re-greasing your axles, it is too thick to roll cleanly into the bearings.
Replacing the Grease on Trailer Axles
Here are a couple of other approved sources for bearing grease from Lippert. Lippert recommends having the bearings machine packed with grease, but a viable alternative is to hand pack them. The video below covers the whole process from start to finish. You can also check out our other blog post about it.

Do not mix lithium, calcium, sodium or barium-complex greases. Mixing these incompatible
compounds can create a corrosive and/or toxic chemical with fumes that can result in a serious health
risk if exposed to the skin or lungs. When converting from one grease to another, make sure all old grease is
removed completely prior to applying new grease.
