Two questions on the B6 section this week! - I must be losing the plot. Last night I was trying to investigate a knocking coming from the front end - I would describe the sound as worn anti-roll bar droplinks - knocking over uneven/pitted road surfaces. Upon taking the wheels off I found the droplinks to be fine - including the roll-bar bushings. Started trying to wiggle the suspension arms round - I noticed a very slight "notchiness" which was audible when trying to move in a circular motion in both upper front arms. (knocking originally started on the nearside, but I now have the same knocking on the offside - so essentially two knocking sounds making the same noise) I removed the suspension upright and removed the arm - what I noticed was that the ball joint was very stiff - the same on the other side. I replaced the arms with the Meyle HD kit around three years ago, I dont remember the ball joints ever being that stiff when I fitted them. All other ball joints seem fine. My question is - would stiff ball joints cause knocking/notch sounds through the chassis?
