Need help with front end!!

you should have someone else check your brakes because thats what the problem is.

you said you have new tires so you can rule them out. if your rims were bent the tire shop (id assume) would let you know about it when they do the balancing so you can rule them out too.

now, if the tire shop put the lugs on too tight that could cause a nasty shaking issue. then factor in that the rotors are warped (shakes more while braking) and you've got a combined issue on your hands.

at the very least have the wheels re-balanced and check for straightness, if they check out ok be sure the lugs are hand torqued back on. test drive the car... if the shaking while driving is gone half of your problem is solved... then apply the brakes and see if it still shakes while braking. if it does your rotors are junk and youll need new brakes... if it dosent the proper tightening of the wheels (torque) now has set the rotors sitting on the hubs squarely which in turn cured the brake shake.

Try raising up the front of the car and put it on jack stands. then grab the top of the tire with one hand and the bottom with the other hand. See if there is any play by pushing with one hand and pulling with the other and vise versa. I think this is a good way to see if your ball joints are bad. Someone else may know for sure. But I dont think there should be much back and forth play if the ball joint is good.
