What is the Best Grease for Trailer Bearings

Question

Question:

We recently bought a new trailer and I re-greased the bearings with GC-LB grease a few months after purchase. Before I re-greased the bearings, they were stone cold after driving about three miles at speeds no greater than 50 mph. Now that I re-greased them, they are slightly warm after the same trip. Is this normal? Thanks

Even though I cannot comment specifically on the grease you used because I am not familiar with it, I can tell you the best grease for trailer bearings is a a grease with a rating of GC-LB, which just means it is made to withstand very high temperatures (like what occur on a trailer hub that has massive RPMs when travelling, even at slower speeds) so it will continue to lubricate instead of quickly dissipating like you see with lower rated greases.

The best grease for trailer bearings is the LubriMatic LMX Industrial Strength Grease # L11390 and LubriMatic Wheel Bearing Grease # L11465 which have the highest rating of of GC-LB to give your bearings the protection they need. These cartridges will fit Grease Gun # L30200 or # L30480 and I strongly recommend using Bearing Packer # L70025 or # ALL647646 to make the job much easier.

You also want to be sure when you do re-grease your bearings to get rid of all of the grease that had been on the bearings because not all types of grease are compatible.

I have added links to video reviews for you to check out as well as a link to an FAQ on bearing grease I recommend taking a look at.

If the hub is just warm then there likely isn't an issue but if it is hot then there could be a problem. You are going to want to check to make sure you have properly used the right amount of Grease # L11390 or # L11465, ensuring that they were packed properly. I have added a link to a video showing how to pack trailer bearings for you which I highly recommend taking a look at.

Hey Jeff, based on your axle info the correct bearing kit would be the part #BK3-310 for a kit that includes both bearings #LM67048 and #25580 as well as a grease seal. This would be all that you'd need as you can reuse the dust cover.
