+3 Replace those control arms and check you ball joints. With the suspension unloaded, and the airbag deflated grab the wheel at 12 and 6 and try to push and pull to find movement. You can then do the same process on the 9 and 3 o'clock positions. There shouldn't be any. If there is, trace it back to the faulty suspension component.
