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 hear a "clunk" sometimes when shifting during "aggressive" driving. The car also shakes during idle (~slight below 700 rpm). I have visually inspected engine and transmission mounts, they look good to me. The previous owner also replaced them not to long ago. Is there any other way of diagnose a bad mount? Thanks

Worn motor mounts will droop noticeably so your exhaust pipes will be low compared to the bumper (assuming they are aligned correctly; there is plenty of adjustment in how they attach to the mufflers). The motor mounts are very easy to replace and require no special tools. The transmission mount is harder to diagnose, as it can be quite shot and still look okay. You can try putting a jack under the transmission and see how far you can lift it before the whole car starts to move. If it's more than 1/2" or so, I'd say your mount is done. Other than that, it's kind of a feel thing. If there is excessive drivetrain movement when you are on/off throttle, changing gears, etc. you just kind of feel it. There's not a great quantitative test that I know if. With that said: https://rennlist.com/forums/996-foru...-for-rent.html
