Clunking coming from rear end - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

humblebeast07 · 10-10-2013, 09:18 AM

So im at about 7800 miles(hard miles..burn outs, launches ect) on my 1LE and I hear....notice a "clunking" with the rotation in the wheels. I work at a mechanic shop , so I decided to put it on my alignment rack, raise up the rear end put it in gear (tried 1-4th) and listen from under the car. I found that the rear diff and transmission make a significant amount of noise(lots of random noises from trans and clunk clunk clunk from diff). Im trying to find out if and one else has dealt with these type of issues before removing my headers and intake and bringing it to the dealer. Thanks

I have heard the slop in the drive line from day one if it was not under a load. I consider it normal.

I believe its happening under a load also, I just can barely hear it because of the exhaust.

I have no noise under a load, and with the nice and quite std exhaust, I would hear it I think. I will say the car has been driven hard, but no burnouts or clutch dumps from any RPM. It does have plenty of no lift shifts on it though, and everything seems fine. You might want to get that checked out at the dealer.

Have you swapped out the Diff and Tranny fluids? They recommend doing them more frequently if you drive it hard.

humblebeast07 · 10-10-2013, 10:44 AM

I have not changed the fluids, and I just re listened to it and it is very loud it almost sounds like a rod knock but its not coming from the motor, I believe its from the trans. Im uploading a video now.

your really here it @15-20 seconds

gajagfan · 10-10-2013, 11:45 AM

Does the sound seem like it is coming from the transmission? I ask because it seems to be the focus of the video.

humblebeast07 · 10-10-2013, 12:20 PM

There are noises from both the trans and diff, but you can feel the clack in the rear end more

davidcroft · 10-10-2013, 01:26 PM

I sent you a PM. I work for Chevy in the Service dept here locally in the Houston area.

humblebeast07 · 10-10-2013, 07:59 PM

Could that be the drive shaft, resonating through the diff and tranny
