Hi all, got a 2003 S4 Avant (B6) and recently started getting a slight knocking noise from the rear passenger side wheel area, only seems to be if I go up a bump slightly at an angle (ie - pull up onto my drive, front passenger wheel first, then drivers front wheel, then it knocks as the rear passenger goes up). Seems to only happen in similar situations and sometimes very rarely at low speeds over rough / uneven roads. Only the once though, if I reverse slowly off, then try it again it wont do it!! Only if I drive down the road and back to the drive!
What the first thing to start checking? Are bushes prone to going on these or top mounts etc? It does have an RS4 anti-roll bar on there that was fitted before me buying it.
