Never come across this on this vehicle.Diffs can be adjusted when new input bearing fitted for correct meshing,but its a pain.cant help wondering if your universal joints on propshafts ore ok.recheck as the biggest symptom is clonking when taking up drive or gear changes especially low speeds.jack up rear till wheels free,in gear,and rotate shaft by hand while carefully watching whats moving and when.diffs i've done less than 5.universal joints ?cant remember how many i've done.dont forget the carrier bearing ,these produce similar symptoms.
