I have an 07 SS/SC with a lil over 18k on it, I don't drive the car as much do to the high cost in gas price, I have a honda civic wich I drive everyday. Anyways.. I decided to take the cobalt out to warm it up. I drove it around and when I came up to a stop at a red light I pressed the clutch in and as I slowly released it to take off I noticed a clunking sound as I'm releasing the clutch in 1st gear. At first I thought it was the motor mount but I didn't remember hearing that noise before. I jacked up the car and visually inspected the mounts, they all look good and intact. So I took the car out for another drive to see if I can hear where it's comming from, but I can't figure it out. Again... it only makes a clunking sound only when I'm releasing the clutch from a dead stop. I drove over railroad tracks and bumpy roads to see if it may be the suspension but everything feels solid and quiet (suspension wise). I even turned the wheels fully from left to right to see if it was the steering but everything was quiet. The car is stock height with stock wheels/tires. The only mods I have is a stage 2, 2.85 pulley, cold air intake and exhaust. Anyone having this same problem? Please, no rude comments only helpful advice or opinion. Thanks in advance...

 

I think it might be play in your half shaft that the passanger side axel goes into so that both axels can be the same length.

 

I'll check that out.. thanks for advice.

 

did you find anything.... I have same issue and im getting annoyed. It only does it evey once and a while to me but mostly when its cold. Let us know please what you find. And it only does it when your stopped and letting clutch engage into 1st.

 

Im having the same problem it seems to me the noise is coming from the passenger side about where the pully is. I inspected it and i dont see any visual faults help please!
