I've put the hood in the service position and the only thing I can find that is loose is in the picture below (yes it needs cleaning!):

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I have an annoying clonk over bumps from the rear of my 986 Boxster S. Not on undulations but on and off speed bumps and bad road surfaces. It's not the suspension, it's been checked, and the position of the noise moves if the hood is down. I've put the hood in the service position and the only thing I can find that is loose is in the picture below (yes it needs cleaning!): The strut can be wiggled and there is lateral movement at the upper spring washer, so I'm thinking of removing the it and putting a spacer / washer below it. However, this 'slack' movement may be necessary. Has anybody sourced this as the cause of a clonk or should I be looking elsewhere?

POST 2Original post

Had this on my Boxster, it was the shock top mount that had failed.

POST 3Original post

My money is on rear trailing arms......... Is it a hollow knock that sounds directly behind the seats??

POST 4 / ORIGINAL POSTEROriginal post

No its not from behind the seats. Suspension top mounts sounds like a possible although nothing obvious can be seen. I'm now not sure the noise moves when the hood is down, I think the change in sound perspective makes it seem like it has moved.

This is a source reference. Confirm exact model applicability in the original material.
