shriekingtires

I recently purchased a 96 Z-28 6M. I hear a grinding/ratcheting sound. The sound sounds like tires spinning slowly on a loose gravel road. This sound occurs for a split second just as the clutch engages and puts power to the wheels. It is most noticeable when beginning to accellerate from a stop in first gear. It grinds just as the car is beginning to move. It does not matter if I am going straight or turning. Turning trac control on or off doesn't make a difference? I have only heard this same sound once when shifting between 1st and 2nd at a slow speed. Is this a clutch problem? Or is is differential? Honestly, if could even be the tires slipping for just a split second -that's what it sounds like, but I can't believe there is tire slippage on the slow speed takeoffs that I do. Any ideas? By the way, the clutch does not slip. I put it in 5th and floored it...no slippage. Any help would be greatly appreciated. Thanks!

Maybe its the peice between the driveshaft and the rear. Isn't that the U joints. Mine was replaced. It also chirped at low speeds like a bird. Annoying.
