Have you came across this before?

I'm in the process of ridding my C70 T5 of all the niggly little things that are wrong with it, and one of those things is a squeak when you accelerate/decelerate especially when driving in traffic, you can't hear it inside the car, but you do notice it if the window is down, I'm thinking drop link or possibly engine strut bush, also there is a jingle when you go over a bump, again you can only hear it when the window is down, I was just wondering if any of you have came across it before or how they cured it?

Could be either or both, the ARB drop links or the top strut bearing.

The jingle u describe could be what I had on my 850, over a bump with the window down,turned out the spring clip holding the rear brake pads steady was missing...
