put the spare tire on the rear. then put the rear tire you took off (the full sized one) on the front.
see if it still shakes.
you MAY have (if you are extraordinarily lucky) just bent the rim.
if the car drives fine with the tires changed, then take the tire which used to be on the front to a tire shop. see if they can balance it. if they cant, then you need another rim.
if the car still shakes then you have a bigger repair on the front end.
any other history of repair?
