i once had 3 studs break. improper wheel fitment. (long story) anyways, went to autozone or something like that. bought 5 lugs for 10 bucks, kinda wedged out the hub assembly and replaced it. it took a long ass time, two guys, and alot of sore muscles. if i were you, i'd cough up the 50 bucks or so and buy a new complete wheel bearing from the dealer.
