I have noticed in the past couple of days that when going over speed humps and when reversing into the garage, there is a creaking sound which I am thinking may be the chassis. I am wondering if it could be the plate/tray/brace that is supporting the exhaust. I had the Nitron's rebuild a year or so ago and when I bounce each corner there is no creaking, so not the dampers. Any ideas?

e.g. diff bush, heard esp when changing gear stressing chassis fore& aft.

You'll prolly need to have it looked at underneath, im afraid

I had this recently, but it was the exhaust that was loose, it a easy fix if it is.

Are you sure its not the roof? Mine roof creeks a bit what i go over speed bumps and particularly on steep slopes where all 4 wheels arent level. Its just the fibre glass rubbing. Unless its a completely different creek altogether?

Ive just had the diff bushes renewed on mine by the boys at Aeromotive and the horrible creaking noise, which sounded like moving bodywork/ fibreglass seems to have disappeared. I'm not sure where the link is with the two though.

I had the same after the OT Grand Prix @ Nurburgring last year.
I also sprayed the a/r bar bushes and wishbone bushes. Seemed to do the trick.

Deffo shunting noise especially in traffic, it was the top one that had gone and I think one of the others was on its way out. 3 bushes in total but the top one is a nightmare to swap. The bushes themselves are fairly cheap but ive had the diff out to replace a couple of bearings so I'm not sure how much they cost individually.

Mine started creaking on a euro road trip, I suspected it was the chassis brace plate thing, anyway when I got home it seemed to stop, drove it again and it started.

Jacked car up and the chassis brace thing was ever so slightly loose, nipped it up and it's now spot on
