Clunk from rear of car when accelerating from coasting
I tried searching but did not find anything that seems to fit my issue.
Does anyone else have this problem? When I'm coasting, not on the gas or brake, often times when I get back on the gas I get a clunk noise from the rear of the car. By often I mean at least a few times every time I drive somewhere, can be dozens of times for a longer trip. Going down hill coasting and then accelerating seems to always bring it on. It's like there is play in the driveline to the rear of the car. If I brake hard I'll often hear the same noise on the downshifts. Had a dealer look at it and they told me it is driveline lash and normal. Per their explanation, Chevy recommends no fix for this and that it is "normal". The car did not have this problem when I bought it and it seems to be getting slowly worse. I also hear the same noise shifting from park to reverse to drive or any combo of reverse to drive/drive to reverse. I just wanted to see if this is common and if anyone found a fix. Between this and the transmission shudder, I am not really impressed with this car anymore, which is disappointing because I love this car. |

Not common at all. Are you still under warranty?

Possibly loose axle nut in the rear. They are marked from the factory so you can take off the wheel and visually inspect it. I know I'm resurrecting an old thread but I had this exact issue and couldn't find info anywhere so I'm sharing to help others.

Sounds like too much play/wear in one of the universals on the driveshaft.
not normal. yes, it could be something internal to the transmission or differential, but that is much bigger headache. You should be able to test the driveshaft freeplay with the car on a lift or ramps. |

To hard to diagnose from a website, when you first get the car everything is 100% tight after that 10,000 components start to become play complacent.

This is from 2020 and the OP did not report back. I wonder if he found the problem?
I had these symptoms in my old 01 SS Camaro and changing my motor mounts, trans mounts and torque arm mount fixed the issue. Trans mount was torn to hell lol.
