Have u tried gettin some wd40 or oil into the joints though some of the rubber boots may be fidly. A ball joint went like that on my old car bugd me for months. I did this on 1 at a time to find out which it was then replaced it. Always worth tryin if ur not sure
 
This is what mine is doing. It's so loud and embarrassing! It's having the nearside ball joint replaced on Monday. I hope it fixes it.
