Can anyone help me narrow down some noises i have on on my 99 a3 1.9TDi.

When driving along i have a rattle which sounds like a bar knocking, i suspected the stabilser links but having checked them last week they look and feel fine.
Whilst looking at these i also checked everything else arms rack etc and they all looked fine to.

Over the last few days though i have now developed a squeaking sound when going over bumps, this sounds like its coming from the rear bush on the bottom arm.

Has anyone else had any similar noises/problems and how did you solve them.
