Is Your Corvette Differential Making Noise???
 

I have an '06 C6. Ever since I had the car (1 yr) I noticed that the rear end made noises when I turned slowly, such as a "U" turn in a parking lot. I recently took my car into my Chevy dealer and asked the service mgr to take a short ride with me so I could have him hear the problem. He never got in the car. He knew what was wrong. He said that GM has been having some differential problems with some recent Corvettes. Apparently some clutches in the diff do not have enough clearance so they make noise and it requires a rebuild of the entire diff. There is no "official" recall by GM, but they are fixing the problem, if you call it to the service writer's attention. He said they have repaired one '04, several 05's and a few '06's. Do you have such a noise in your rearend?
Take it to your Chevy dealer. They'll fix it...whether your car is in warranty or not.

Had the same problem and the TSB calls for fluid replacement first and if that does not fix the problem, then replacement of the clutches. Had both done at my local dealer and the clutch replacement fixed the problem.:thumbsup:

rearend noises,
 

My C6 has a bit of a rearend chatter though not bad at this time,im not in the habot of doing holeshots so ill keep an ear on this problem, has anyone had a problem with stiff slow shifter opperation almost acts like it would if it was below 30 outside.

Hi! I have 2000 C5 with about 54,000 miles on it and get that same noise on slow turns. You stated that the chevy dealer will fix this whether the car is in warranty or not. Does that hold true for a vette my age?

Hey, cwbeachbum, I'd take my C5 into a Chevy dealer and chat with the service mgr. If your car is truly making the same noise as mine due to the same problem, I'd say they'll fix it. It sort of ticks me off that there is no
general recall.
06 C6

:exactly:

My C6 '06 had the same rear end noise- only when backing up slowly and turning. They replaced the fluid as a first try- has been OK since then (about 3 months), but we'll see. Thye did say that if the fluid change did not work, would have to be rebuilt.

differential nosie
 

Hi. Thanks for the response. Just wanted to let you know that I had the differential fluid changed by my local corvette specialist here in clearwater and the noise has gone away. :dancer01: The problem I have now has to do with a very slow internal leak in my 6speed tranny. It only makes the casing greasy and leaves a spot in the driveway smaller then a dime. My mechanic checked it out and told me it is an internal leak and checked the fluid level which he stated was okay. He suggested I wait till I replace the clutch to fix it but I keep thinking this should not be happening. The internal seals should last longer then 57,000 miles and feel this is a factory defect. Have you heard any others having this problem? Thanks in advance, Phil

Only time i hear noise is when i'm backing out or turning into park, i always thought it was the tires rubbing.

Just going to a dealer scares the crap out of me!

Any 2007 models with this problem?:D
