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.

POST 1 / ORIGINAL POSTEROriginal post

Hi-I have a 99 996 with 92 k on the odometer. Recently it has begun to make a distinct audible rattle when going over rough pavement. I think its from the rear. I plan to get it up on a lift and inspect it myself before going to a shop. What to check and look for?? Thanks in advance for any answers and advice.

POST 2Original post

These 996's are known for the cat converter elements breaking free on the inside. They rattle. Check that first. Check your wheel torque as well, could be a loose wheel. Chances are its the converter. They can't be fixed, so you'll need to replace them if that's it.

POST 3 / ORIGINAL POSTEROriginal post

Thank you Tony! It turned out to be a very different source for the noise that I had imagined. The intake air box rests on 2 prongs that fit into rubber socket grommets that are inserted into holes in the rear crossmember. The grommets were missing, and the air box was dancing around causing the rattling noise.

POST 5Original post

Ah, was it this little guy? 1999 Porsche 911 Carrera Coupe - Intake System - Page 1 . Glad it was a simple easy fix.

POST 6 / ORIGINAL POSTEROriginal post

That's the piece Luccia- I will order a couple soon-I just need research a few more parts to build up a decent order.

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