I just listened to your post... sounds like grinding. Brakes?

Hell, I don't know. Start cutting the legs off of the elephant.

Put it on jack stands and see if you can replicate the problem with no load on the suspension.
Yup I've tried that all ready, the wheels just spin on. . . what's weird is today it didn't even make a peep(only drove 5miles in total today though). . .another clue that might help is the car right away doesn't make the noise as soon as I start driving(almost like it needs to warm up or something), the noise eventually appears after I've been driving for awhile.....it seems to reset every time the car sits parked for a while, which leads me to believe it's the diff(as much as I don't want it to be) be then again makes no noise when driving straight, so. . .don't know

Good Luck
The noise has always been there. . .even after the suspension was changed, U joints didn't even of that lol, I'll be sure to check this weekend

I did a gear swap last year to 3:73's Biggest gain out of every thing I've done to the car. It will put in in your seat however, if i were to do it again I would put 4:10's in.

Be careful if you are considering buy a gear kit from AM, LMR or one of the other ones there are considerable differences in each of the kits.

Again if i did it over I would just buy the ring and pinion and would buy bearings, shims, oil and all the other stuff from NAPA not that much more in cost, you can feel and see the difference in the bearings.

Although you do need some specialized tools it really is not that difficult and i would be willing to provide pictures and guide someone on how to.

Make sure that the floating pins in the calipers aren't seized.

Default Update

Hey guys just an update on what I've done so far, I've checked my u joints everything looked ok when i raised my car, I really don't really think that's it though, I've also change out my fluids in my differential everything in there looked okay gears had no signs of wear, so i put back together and tested it out, nope the noise is still there, so I thought about greasing up the rear wheel bearings to see if that was it, again the noise is still there, at this point I'm thinking it's the clutch packs any thoughts???

I'll make sure to check those floating pins in the calipers though

Late needed Update 2 February 2nd 2016
So after making a couple hundred miles trip from Savannah GA to Asheboro North Carolina the noise has seem to have gone. I actually pin pointed the noise was coming from the diff. I guess the fluids in the diff were not getting to the right places since the car did sit still most of its life. Huh go figure, if you don't drive a car enough it breaks.
