I was at the track today and on my 2nd run my car i took off at about 3500 and people said my mirros were shaking my exhaust and everything thing was shaking really bad. so about half way down the track i felt a vibration in the wheels so i slowed down and coasted through the traps. it felt like my rotors were hiting against the studs. so after that i checked everything out and couldnt really see the problem. i took it to my garage got it on the lift and only under acceleration you can here a clinkin choping sound and it looks like the driver side axle is shaking what could it be the axles or inner part of the axle that goes into the tranny? i need to know the part # on that
