I suggest getting new spring isolators (i think that's what they're called). They're the pieces that fit over and under the spring so that it isn't directly rubbing the control arm. If yours are stock i'm sure they're shot to pieces, mine were/are. Also if you have the money this is the perfect time to do rear springs. When you pull the control arm the spring is gonna be removed so its a great time to knock out 2 birds with one stone. Have fun,
