well my mechanic was doing a check up on my car, he took of the wheels and put them back on he told me wat the problem was so i got my car and headed home. when i get home i jack the car up and take the front right tire off then i go to the driver side and the lug nutz were tight like a mofo!!. So i put pressure and the hole thing breaks off nut and screw so go to the next one to see if it the same problem and it also broke off,so i want to know if can i replace the screws or i got to get a new hub? and if i do were can i get one cheap?!!!
