Trailer hub replacement

[Blue_Runner]

A couple reasons for changing the hubs. I got the trailer with working drum brakes. Well, they died pretty quickly and I disabled them but want to get rid of the two hubs with the big azz rusty drums on them.

Secondly, after beating bearing buddies and dust caps on/off over the years I believe the hubs may be damaged to the point they don't seal as well? And third, I was thinking galvanized hubs would be better.

My thinking is, if I'm gonna replace two hubs I might as well replace all 4 at the same time.

Great info - thanks guys.

p.s. Destroyer I believe my bearing buddies popped off cause 1) I over packed the grease and 2) there was grease on the edges when I put them in. Still, I'm not a huge fan of buddies....but they are certainly better than nothing at all.
