Good point. Floyd is right--there was a Chevy hub that was a bolt-on replacement for the U-Haul
And, some have replaced the whole axle
with a new one [Dexter, maybe?], that then gives more options. [though wheel offset still is a fussy point]
Hubs don't often fail on the U-Hauls, apparently.
is now making new wheels available, on eBay I think, though they're not always
available..... some folks have had to wait a while before the next batch comes along.
My $.02's worth..........
