Differential Trouble
I've got a 2004 C5, with 11,000 miles on it. Took it in to my local Chevy dealer for an oil change yesterday and the service manager called me over to show me a leaking rear differential. Claims this is a rampant problem with Corvettes (in fact, on the next lift was another C5 undergoing repair for the same thing). Says he's seen this on Vettes with as little as 4,000 miles on them. Repair involves removing the diff cover, replacing the rubber "O" ring, and slathering on some sealant around the whole thing -- $500+!! I asked him why Chevy didn't just do this during the manufacture and get it right the first time. My question: is he telling me the truth or am I about to get ripped off? Is this a "normal" problem?

I recently got together with some forum brothers and had my differential leak done. When I did it, I wanted the entire rear suspension removed so that all the sludge from the leak could be removed off the differential and tranny. Here's the thread on it if you're interested...

Hi eiswerth -
True, but you can alleviate the cost by doing it yourself if you are handy with tools and have a jack and jackstands etc.

Yes, it is a common problem with the C5s. Mine leaked three times before they finally got it fixed.

Yes. This problem is notorious with C5's. I remember a recent thread (and I apologize I can't reference it here) where someone mentioned they only paid $400 at a dealer to have the repair done.http://forums.corvetteforum.com/show...727&highlight=
