Twice last season. Front axel first. Rear axel a month later 500 miles from home. Lost a wheel somewhere in Buffalo. Had flames in my review years ago in downtown Hartford with a conventional hub. Pulled off road on Asylum Street. As luck would have it a Champion Dealer 10 miles or so down the road. Some great locals helped me out and got me back on the road. Trailer my weak link lately.
All it takes is a little maintenance. If a good hub oil is used then they can run without oil for a good while and not have a huge problem.
In 9 years I've only had 1 out of 4 get water in it.
