rear end noise

[daking]

I just wanted to post something about rear ed "noises" or chatter. Just before I put the car up (06Z)I had the differential fluid flushed and changed, I had it done about 7mos ago and it was mostly quiet for the summer when temp dropped it was more noticable, anyway I had them put in the new lube which is called DEXRON ,did a bunch of figure 8s and the noise, plate chatter ,was gone even in the colder temps. The other alternative is repacking or changing of the plates which I really didn't want to do. just athought for others who I'm sure have this problem

I have the same problem. The noise occassionally comes back and goes away with some tight turns. What I want to know is if this is an indication of permanent damage to the plates and should they be replaced now rather than later.

There are a couple of service bulletins on rear axle noise posted here on the CAC. One is under chassis while the other is under driveline. Check them both out -
Corvette Action Center Knowledgebase :: 2005 - 2007: Service Bulletin: Rear Axle Clunk and/or Chatter Type Noise on Turns

Corvette Action Center Knowledgebase :: 2005 - 2008: Service Bulletin: Rear Axle Clunk and/or Chatter Type Noise on Turns

This second one calls for using the new DEXRON fluid.

My '06 was serviced twice for the rear end noise. I'm not sure whether I have the new DEXRON in it now or not but it's not making any noise now. My '08 isn't making any noise and it's an early production car.

I still hear about '06s having the noise and some '07s. A lady I know at work bought an '06 Z51 car recently and heard the rear end noise. Guess the previous owner either didn't hear it or didn't care. She's taking the car to the dealer for the DEXRON treatment.
