Well when I put the pedal to the floor lets say if im rolling in second gear and I just slam the pedal to the floor I hear a big squeak or snap sound coming from the bottom of the car right when the car jolts, or atleast thats where I think its coming from. It only happens when I am rolling and I hit the gas hard. It is almost like something is loose and when I hit the gas it snaps or squeaks or click or something like that. I think it is getting louder, I remember hearing it before but never this loud. Also is it normal to feel the rear end loose? Its like when im turning into my parking space I hit a dip thats there and when my car rocks side to side it feels real lose and it makes a snap sound more like a loud click.
