While you do the change or have it done have all of the u-joints checked. There will be two in the drive-shaft and two in each half-shaft to each wheel. Is your car an AT or a MT?

What is condition of fluid - black and/or smelling burnt. It will need to come apart. The differential case and /or components (posi unit) more likely. Pinion and carrier bearings usually will make noise all the time. Noise only when turning normally involve parts required for turning: Wheel or hub bearings, half shafts, and the differential pinions within case. When turning one tire speeds up the other slows down. If your question is costs, you need to diagnose where noise is coming from first.

If he responds with I've never added fluid, checked fluid and have driven it 100K miles well then maybe BUT I believe there needs to be a "PLAN" and the tear down isn't the first step.

I actually just got the car last summer.Put around 200 miles on it since.I will have the rear drained and filled with the fluids mentioned,then go from there i guess. If i have to i will take it apart.Just never delt with this problem or worked on a vette rear end before.

Drain the fluid completely, refill with GL5 80W90 and 2 bottles of GM 1052358 additive and drive it. Maybe do some figure 8's in a large parking lot. You'll need to pump the fluid out using a suction pump. I don't believe I'd use the synthetics in your particular situation. Have you ever checked the rear differential fluid? Check for obvious leaks at the differential, the front at the pinion, right and left sides to each wheel.
