Slight clunk from drivetrain when accelerating/slowing down

[messenio]

I began to notice over the weekend that my car is making a clunking sound when I'm giving it gas or releasing the gas, usually at lower speeds. It almost feels like there's play somewhere in the drivetrain, maybe the CV axles or diff. It doesn't happen all the time, but I can usually recreate it by driving at about 5mph or so and alternating between gas and coasting. It's not very loud but I don't remember it being there before, so I was wondering if this is normal... The car drives normal in every other aspect, and it's a CVT by the way.

Could be just that oem rear motor mount that's causing that sound the material is very soft and has alot of play

Thanks, do you think it's something warranty would take care of, or am I just nitpicking?

I wouldn't say nitpicking since I was in the same, I doubt warranty would do anything about it since all the factory mounts are very soft to prevent in cabin vibration and for a smooth ride.
Down side too that is you'll notice engine movement especially once you're making more than stock power, that's why I upgraded mine to the Hasport motor mount posted above

Hey dude, did you get your diagnosed? I know it's an old thread. My SI is making a similar clunking noise now. Started maybe a could weeks ago, and thought it was just a thermos rolling on the floor when driving.

Nope. I traded the car a couple years ago. I did end up replacing that rear motor mount and it helped a bit but not completely I remember. Best of luck!

the oem rmm in my Si is so bad. brand new, it moves way too much. i get that they need to reduce vibrations, but i think they took it too far.
