Knocking from rear end

As above I would try removing the vcu and props as a process of elimination.
 
This isn't a rear brake shoe problem is it?
Well, the noise changes when I brake but not when I pull on the handbrake whilst moving. I have noticed that one of the brake back plates seems to be split, unless they are meant to be like that but the opposite one doesn't seem to be split.

Drive one wheel at a time off a kerb to see if it makes a bump. Also drive one wheel at a time into a kerb to see if it makes a bump.
 
If it makes a bump, what will that tell me? My wife, the world renowned mechanical genius, reckons it's a drive shaft. If she is right, I'll have to kill myself.

Bumping one wheel at a time can point out which wheel/corner of the car is affected. Or linked to the fault if the bump relates to one wheel and not the rest. A possible process of elimination.

The back plate is split? That doesn't sound right Col - do you have a picture you can upload to the forum?
 
Ever find the solution to this issue?
Yes, I turned the radio up louder. But before I did that, I had the wheels off and couldn't find anything that accounted for the noise. The back plate on one of the rear wheels had cracked and I removed it but that made no difference. Apart from the knocking, other issues started developing, such as, the rear window would sometimes open of its own accord, often in the middle of the night whilst parked. Then some days the rear door would refuse to open. There was a miriad of not serious but annoying faults and it was coming to the end of its mot so I sold it cheap to someone who was willing to deal with it. It was a great car though and I enjoyed driving it even though it was the underpowered 1.8 Now I don't work anymore, we don't need three cars so it had to go, I've still got my beloved series though.
