    Easy way to tell; put yourself a 3-4 foot prybar between the mount and crossmember and pry up and down, there should only be 1/4th of an inch or less of travel. If it's traveling more than that, it's bad and if it's traveling a lot more than that, that's more than likely what's making the noise.

    Cammed Goat mentioned the carrier bushing on the rearend cover; I would listen to him and check that too. I know that would be a nasty thud noise if it were worn too.

    The mechanic is still at a loss and at this point cannot find the what is causing the problem. He too believes that the noise is coming from the differential. I used Mobil 1 synthetic and equa torque(manufactured CRC) friction mod. Is there that much of a difference between the GM products and what I used?

    Never heard of Equa-Torque. I have used something called Trans-X by CRC. CRC is compatible with GM-specific diff fluids.

    Another thing I heard about with our cars. The half-shaft bolts tend to back themself out of the inner axle stubs. If they weren't checked before, check them asap.

    it's clicking under the initial movement of the car? Could be a u-joint issue.

    Alright, I got the car back from the mechanic and they said that they heard the noise but could not figure out what it was and recommend that I go see a shop that specializes in differentials. Taking one last ditch effort I decided to empty all of the friction modifier (5 ounces), instead of the recommended 1 ounce that it states in the manual, into the differential to see if that made a difference. Oddly enough it seems to have at this point eliminated the noise. I will post any further developments if the noise returns.

    Sounds like the "Thunk in the trunk" problem. Google it. Your GTO may be eligible to be repaired for FREE if it was built before a certain VIN and this is the problem. Mine has been doing the same exact thing, I thought it was maybe the U joint or a bushing issue but I couldn't find anything wrong. I took it to a speed shop, and they said the differential is fine and the car is still making the noise. I am taking it by the local GM dealer after I get back from out of town and hopefully mine will get repaired for free. Take it by the dealership and ask them about the service bulletin at least, they may actually be able to help you. There's tons of threads about it on Tech and the GTO forum. Hope I was helpful, the noise is driving me nuts too so I feel your frustration.
