ya people have hubs go out on their titans. one of mine went out. they cost like 120 or so from the dealer. you can do it yourself. its not to bad.
I paid $10 for 3/4 drive socket and $35 for a 3/4 drive 40" breaker bar + shipping. So yeah, probably $50 to remove one nut. But if the dealer wants $450 for the install, that makes me feel better.I think I tried 32mm and it didn't fit. U might be right though. These things are not cheap. Oreilly/checker rents them out.
