I'm not sure about your hubs, but I'm on the 3rd replacement set of SuperWinch hubs on my 2000 Rodeo, and they're clattering again. If I was going to do it all over again, I'd do it with WARN hubs, the Superwinches are built to function, but not to last. They don't mind replacing them under their lifetime warranty, so that's good; but that's it.

Also, as to do with dealer warranties, be careful. I'm currently in a law suit with Isuzu regarding not just the dealership, but Isuzu corporate refusing to replace parts on truck at only 42k of my 10 year/120k warranty because of my aftermarket mods. (they're claiming my 2.5" suspension lift has caused 3 transfer-case failures in 36k miles becuase the u-joints in the drive shaft has been put out of spec by the lift)

I'm fairly certain we'll come thru this on the good side, but I'm having to spend 8 months and have a team of attorneys to do it, and at the end I'll never be an Isuzu owner again.
