I had the same thing for a long time and I thought it was 'tie-rod' ends and shot grease in them (needle gun through rubber boots) and only got a slight relief. It sounds like the old sqeaking rigging of a wooden sailing vessel, right? I remained puzzled until the ultimate diagnoses took place,..........the right lower ball joint busted completely off the lower control arm. I was lucky,....it happened on the way to church at 30 mph, not at 80 mph 150 miles away from home, just two days earlier. Get a good mechanic on your front end if you don't know how.
