I have on 05 with about 35xxx miles and for the last 5000 mile at higher rpm if I leave it in gear in the first and second gears it sounds like a bomb goes off if I give it full throttle or let go of full throttle. ex= going on the high way around 55mph drop it to second gear 5600rpm or so hit the gas 100% and it feels like what it felt like when I lost my rear diff bushing, bang clunk. or let say I'm coming off an on ramp and I get on it 100% gas to 60mph and then push the clutch in or take my foot off the gas then BOOOOOOOOOM. I got the tech at Moore in Va to look at all the bushing and the motor mounts and they came back good. The car has not always done this and yes I could drive around it by keeping the car at 40-50% throttle after 4500rpm but that is not what I bought the car for. What do you all think it is, The transmission or the diff?

There ya go! :thumbsup:



Sorry, I couldn't resist. Seriously though, it's obviously mechanical backlash from something. It could be the flywheel, the driveshaft or the rear diff. I can't advise you further than that without experiencing it, but that's where I'd look.

If I had to guess I would say the front mounting bushing on the rear differential... That's where I'd start anyway...

I have to agree to Drift-caddy... and then James is right, I'd start with that front bushing.

Haha. When I saw the sticky telling people "Stop making 2008 CTS threads", I was tempted to start one like:


"2008 CTS: Will 22's and Lambo doors fit??"


In the end, good taste prevailed.

You might have left a big MagLight loose in the trunk. It makes a large sound during your launch. Don't ask me how I know... Should have seen me last night in my track, starting and stopping and listening, trying to figure out WTF it was. :helpless:
