i was changing a wheel and the lil thread head that holds the wheel to the car bent out of shape and broke off. now im curious as to how to fix this. i have one less bolt that i can tighten on the wheel to the axle. how much of a 'doh' situation is this? am i royally screewed? lol

Wheel studs are fairly easily changed, but if your not mechanically minded, best to get a mechanic to do it. Shouldn't cost more than $50 fitted. You should be safe to drive on 4 but I would recomend fixing this sooner rather than later.

your lucky i had one cross thread and could not get off at all had to cut mag off was a long time ago diffrent car as above can be driven with 4 bolts just get fix

The car is still safe to drive, if that's what you're wondering, but as murph03 said, get it sorted soon.

is the hub bolt hard to replace?
any got a quick walk through?
