I just replaced one on my yj last week and it was a more metallic sound, kinda like something was rubbing on the backing plate when I would make a turn. My vise was too small to do the replacing so I went to Advanced Auto and rented (you get all your money back when you return the tool) a ball joint/u joint tool set and it worked ok. When I put on my reading glasses it worked better
I still have a squeek in the front but haven't looked to see just what it is. I also greased up everything there was up front while I was working there.
Maybe try spraying some silicon spray on rubber parts up front and see if it will go away???
