Passenger front wheel feels like it is wobbling like it might just wobble off! on 2002 Buick Century

I know the front pass brake pad is cracked. I am taking it into Firestone to replace pads. The past week the wheel feels like it is wobbling and might even wobble off. If you let go of the steering wheel while driving in a straight line the car would literally drive immediately into the curb - pulling to the right severely. I think its odd this just happened all of the sudden. Any thoughts? Thanks! Lindsey

Sounds like you lug nuts are loose, maybe the person who checked and found the cracked brake pad forgot to tighten the lug nuts?? Whatever you do DON'T drive your car until you get this figured out, or you may really hurt your self or some one else!!
