I am in the middle of repacking bearings and trying to decide on what grease to use. I have read use a marine grease, and others just use a regular bearing grease if in freshwater. We are only in freshwater, and I have high temp brg grease I was going to use. I figure if I put on new seals and dust caps to keep out water then I dont see why this wouldnt work. Its not like the bearings themselves are running in water and you have to keep grease in them under water. Seems to me like if you get much water in them its not going to matter what grease you use it will be contaminated
I found some marine grease locally at oreillys, its kind of a light green color, just seems like it would thin out but maybe not. Says it is ok for trailer bearings but not high temp applications. I can use it, just seems like the high temp grease would be better in a bearing?
Any thoughts?
I also plan to use plain dust caps, maybe with a little sealer around them. I know many run the bearing buddy caps, but honestly thats what was on the trailer now, and havent had great luck with them. If the cap didnt fall off and throw oil everywhere, or the inside spring of the BB not stay seated and come apart inside the hub etc etc they might work. The hubs were not packed full with grease (bearing buddy style) and even with weak seals did not show much water contamination outside of the BB that came apart and it has been several seasons (if ever) since the hubs were opened. Seems like good seals and good caps woudl go a long way to keeping water out, along with letting them cool down a little before going in the water to keep from sucking anything in that way.

While it doesn't say it is for boat trailers on the tube, it does show pictures of regular trailers, cars, trucks AND boat trailers as its useage. Seems everybody has their own grease but it is all probably coming from the same source or sources with different color dies added. The fact that you use any grease for a wheel bearing is good. And yearly maintenance is all you will have to worry about as well. Any grease will do the job if maintained yearly... To coin a statement one of the iboats has on his post, Any grease is better then no grease...AMEN!
