Front end clunk/rattle

[g1344304]

A new, very annoying clunk/rattle has started on my M Roadster, somewhere at the front end. I was going up a level in a multi storey car park and had to stop at the top of a ramp due to a car ahead. One of the front wheels stayed on the incline while the other rolled onto the flat surface. I guess the chassis was kind of stressed/under tension in this position and something from the front end moved. I felt and heard it straight away. I drove the car out of the car park and noticed this new clunk/rattle from the front end. I immediately thought the strut brace but this wasn't the case. Had up on the ramp at a local indy but all bushes etc are fine. It almost sounds like the bonnet isn't secure. Any ideas?

Bulkhead braces would have been my first thought, but sounds like you have checked them already.

...I immediately thought the strut brace had detached but this wasn't the case...

I agree with srhutch - did you just inspect the bulkhead braces or re-torque them? Mine needed only half a turn of one nut to cure an annoying creak.

Really stupid of me, it was the brace. The nut had jumped a thread. It felt tight by hand but loose with a torque wrench.

The obvious places to look for a noise like you've described and which might have been caused in the scenario which occurred, would be:
1. The brackets which retain the ARBs and the chassis which holds the bolts for those brackets
2. Drop links (have bearings inside the rubber covers)
3. The top mounts (have bearings)

But you say these have been checked
