If you have the limited slip rear end, did you add in the friction modifier when you changed your fluid?? I'd pull it back apart. If there are small metal pieces in the bottom that look like half circles, then it's really nothing you did and is a common problem with the factory limited slip clutch pack. You can either have it rebuilt by a shop, or go with a locker. If you go locker, you can buy a Powertrax unit and install it yourself in your driveway since the carrier does not have to come out of the truck.
