View Full Version : Boat Trailer Bearing Grease???????????

02-11-2008, 11:02 AM
I've had me boat trailer about a year now and I've not greased the bearings yet. I know that is one of those to do maintenance items. My question is what kind should I use? What would give the best protection for fresh and salt water? I use my boat every week all year long.

A good, name brand marine grease. Don't mix two brands of grease in the bearings. Sometimes two of them mixed together is a runny mess because of reactions between the carriers. If you have bearing buddy type hubs, only add enough to barely move the cap out. Too much can blow the seals.

Use a high quality lithium grease. It doesn't matter if it says "marine" as some of those aren't worth spit and anyone can label it "marine" if it's a little water resistant. You want a high-temp (continuous service) grease that resists water washout. Trailer wheels are generally smaller than your car/truck tires and the revolutions per minute are higher, generating alot of heat. Kendall Super Blu High Temp EP L-427 works for me, but there are several others.

If you've got bearing "buddies" that have a pressure release (ie, you add grease until you see it coming out), you can "change" the grease by adding until the new grease shows up--just be sure to use a different color grease and to add until you don't see the old color anymore. That being said, I'd still pull the wheels and check the bearings periodically.
