Clunk Bushing - Differential

[Benz280]

Have identified a slight clunk when accelerating and deaccelerating from the differential, flex joints / joint's all ok. 
Occasionally, I hear about the Clunk Bushing - or just a slightly worn pinion gear ?
Owning a Pagoda is constant quest for more knowledge

I had an odd clunk and after checking everything it turned out to be a loose brake caliper - just loose enough to make a clunk. 

Worth a try.
