I've got an 03 GT and this is now my fourth replacement for the front wheel bearing (two left, two right). I've had them all done at Big O' Tires (I don't have time), and the replacements have been under warranty (< 1 year). I've got 242k miles, but most everything up front is new: shocks, control arms, CV axles, tires, etc. Steering isn't loose, alignment is perfect. Is it something they're doing that's burning these up? I'm using the lower-end stuff from CarQuest (it's next door to them, so that's where they buy), but I'm thinking of having them upgrade to a Moog assembly. Can installation problems lead to a bad bearing?
