Default bearings

I clean my hubs and bearings with gas, then dry well, it basically evaporates and then grease well,

Take it to a self-service car wash or use a pressure washer.

i agree, diesel fuel works great, stay away from gasoline because the fumes are explosive and gas tends to leave a residue that can attack some greases. Brake cleaner also works good but make sure you protect the bearings from rust after you clean them.

Don't use compressed air to dry the bearings. Most compressed air has some water and dirt in it. If you spin a bearing with compressed air you can over speed it and the rollers can launch out of the cage like missiles!

Yea I meant that I didnít want to take it down the driveway, slightly, sarcastically. But I did mean because Iím worried of how much gunk is in there and could cause possible failure. The trailer is used, but I have no idea when the last time they were packed so Iíd prefer to start fresh.
I am going to take the bearings out and re pack, so your saying I should use diesel or me cleaner and that will take all the old dirt filled grease out of the bearings? Then just re pack from there?

Diesel fuel will dissolve all the old grease pretty quickly. Brake clean is expensive and makes a bigger mess when I use it.

if your going to do all that work ( which i agree you should since its a used trailer ), instead of cleaning and repacking, just replace the bearings with new! same amount of work and bearings are cheap enough to not do it!

Find out spindle size(s). Take old hubs off the spindle, throw the hubs in the trash, put on new hubs.

Ironically, all of that "gunk" is probably what has kept it from failure. You can grease hubs every year, never clean them, and after a while they look like crap. That doesn't mean they aren't protected, it just looks yucky.
Also, leaving it messy makes it more difficult to spot a potential problem.

I contemplated this when I got our new to us boat a few years back. Found a local trailer shop that would do it, labor and parts included. $65 per wheel. Problem solved.
