I have a lincoln ls 2000 v8 and when i turn the wheel i hear an awful noise a squeak sound its loud i checked the ball joints and there good that is what it sounds like a bad ball joint but there's no give or play in the wheel . I replaced the power steering pump yesterday an that didn't help either tie rods are good im running out of ideas.even When I push up an down on the body I hear the same noise also. PLEASE help me! -Donovan huff

have a pro load test the ball joint,, it's not easy unless you've done that for years.
