I have had a knocking noise for a while from the front of my 2007 197, changed inner tie rods and track rod ends and the noise seamed better but I have since noticed it's still there, getting worse than it was before. (There is no play in the wheels now tho so changing those parts wasn't a complete waste of time) is ight be coming from inside the rack where the inner tie rod screws in would this make sense and if so anyone go any info on what it might be? I seen a bush that goes in there maybe that? Thanks in advance for any input
