Might check the shimming of the sun gears in the diff, they may need an extra shim under them to move them closer to the spider gears. This is something that has been talked about quite extensively with the sc 4x4 trucks gear diffs. I haven't ran a gear diff in my SC10 since the first generation of them. I would start there.
