At first it didn't bug me but after awhile it started to get to me i took it to the gm people and they said there is nothing wrong with your car, well the noise isn't so much as a clunking it sounded like a squeaking but i found out that its not the issue i talked to my mechanic and he said it was a grinding sound, so of course he said what the part was called and i can't remember but he did go to see if it was being recalled but couldn't see the page cause it was being blocked on gm's side!!! i'm truly annoyed cause that part is expensive!!
