Boat trailer - Axle grease

Haven't greased the bearing buddies on my trailer in awhile and need to purchase a tube of grease. What is a good grease for this application? What is everybody using?

Re: Boat trailer - Axle grease

I hope you have Bearing buddies or some other hub with a grease fitting, Zerk fitting.

The quality of the lube isn't as important as keeping them full and purging any water. When a trailer moves it pushes the greas in the hub around, and it heats up. the air spaces and the heat/cooling causes moisture to get into the bearing. I always give my bearings a small shot of grease befor pulling it into the water. The warm bearing will cool in the under water condition and that means a vacuum will pull in some water, bad news. really no way to seal the bearings and the rear seals mostly leak.

So that a side. While any chassis grease will do; you can just buy a lithium based Marine grease tube at Wal-mart or other discount store (usually less than $5).

If you are hand packing the bearings; I'd suggest getting zerk fitting type dust caps and replacing the rear seal when you take the bearing out (obviously clean the bearing in some solvent and check the bearings and race for any cracks or roughness. And make use you pre-load the bearing if you hand pack them.

Happy trailering
