Hello fellas. I have been putting off changing my creeking arb bushes for a month now and the other day i noticed a small knock coming from the front right side when i go over bumps at slow speed... About a week later, it is now a much more noticeable knock from both sides at slow and medium speeds over even slight bumps. Slight vibration at high speed but not bad at all. Could this be just the arb bushes...? im worried the steering rack could be shot. Any ideas please? Cheers. Dave.
