Lots of play in rear prop.

Hi folks. Went for a spin down to the shop and back (6miles), all was fine on the way down there...but on the way back, under acceleration 40-50mph, i noticed a dull grumbling/vibration. Instantly i thought UJ's (which were replaced 3mths ago). After investigation... uj's are fine, but i can now turn rear prop 1/4 of a turn.
Questions:-
Is it likely to be the diff end or gear end? Does anyone know of an easy way to find the prob???

Do any of you nice folk want to buy it (totally standard td5 90 pick-up, 66k miles on a w. Big folder full of reciepts and history from prev owner).
