Yea, that sounds like mine...along with some other not so super sounds.
Little grinding here and there.
How dangerous do you guys think it is driving the car like this?
Considering i would be using the highway simply going straight..no turns. (Clunking noises only happen on slow turns)
Weighing my options until these parts departments open tomorrow

As Bruze stated above (and I did too). Don't bet against the engineering recommendations for fluids. Falling for some marketing spiel that an aftermarket fluid is as good as or better than the factory spec is just crazy. It's like using one's intuition to challenge engineering.
The diff fluid formula must be important BC GM engineering has adjusted it twice. since C6 introduction.

I did mine a couple of years ago with GM Dexron. This was the first time I ever changed the diff fluid in any car. It was VERY easy to do. I drained exactly 2 quarts, and refilled with 2 quarts. Once done, I went out in our cul-de-sac and did a number of figure 8's. I've never had any issues or sounds etc. Trust me, it's an easy job to do.

I am towing from Texas a trailer with my 08 Z06 while on a 5 month road trip so I stopped at a shop outside of San Fran and bought Amsoil severe gear 75-90 and additive for the rear end and synthetic ATF for the tranny. I found a shop in Napa to replace the fluids and noticed a difference immediately with smoother shifting.

Yes, I published this before but unable to find it. Take a look at the pics. Cut a piece off of a 10mm allen key (about 20mm long {a strong 3/4"}), round the six edges on two sides. Use it as a special tool with a 10mm box wrench.

Thank you! What did you use to cut the Allen key?

I have a dremel tool with a small 1.5" dia cutoff disc. They sell them in packs at Lowes or HD, but you need the arbor too. Be CAREFUL with this little cutoff wheel. Cut half way through either side instead of all the way on one. Clean it up on a grinding wheel. Keep the piece cool while cutting. If you overheat, the cut slot will expand and grab the wheel.

Not a likely scenario but it is possible. Just a little tidbit I learned on the forum and thought it should be passed on once again.

Yea I was able to get the fill plug off but I just had trouble with the drain plug because of the clearance issue. Thanks for the info!
