if it only dips a little with you out of the car, turning the wheel, and tilts alot with you in the car, turning the wheel, its most likely springs. remember the shock is only a damper, if the springs are broken or worn it'll still sway and dip. i also had both front springs broken at the LCA pocket and never noticed 'till i pulled them out. (ironically my front end sat too high--WTF? :? ) what kind of shocks did you use? did the problem change at all when you installed them?
just to be safe, jack up the front of the car (both wheels, use jackstands under the frame.) and with the steering unlocked, grasp the tires on the sides and carefully wiggle them back and forth looking for play in the tie rod ends, and for binding in the ball joints (turn the wheels lock to lock for the BJ's). next, grasp the top and bottom of the tires and wiggle them, looking for excessive play. now place a pry bar under the tire and lever up and down. you may want a second person to be your eyes for this. look to see if the spindle moves vertically on the ball joints.
is it when you turn the wheels right, the left side goes up, or turn right-right side up?
the squeal when you hit the steering stop is normal. you don't have to worry about it.
