While it could be an issue in the diff, the most likely cause of clunking is insufficient.........or non-existent...........vacuum to the modulator.

You'll need a vacuum gauge and you'll need to T it into the modulator line (the line to the transmission) and put the gauge in the cabin so that you can watch the gauge while you drive it. My suspicion is that your gauge will read zero or very close to zero under all conditions.
