Used 3.5K trailer axle hubs with bearings and seals. $5 if you want the new dust caps. I took these off my car hauler to install brakes on my second axle and they are in good, working condition.
One stud has some boogered threads, but you could just run a 1/2"-20 die over it or replace it pretty easily with a new stud.
These would be great spares to throw in your toolbox so you don't get stranded in the side of the road!
Pick up in the Albuquerque area or you foot the shipping costs.
