Clunking at rear of car when going over speed bumps and uneven ground

When driving in normal condition I experience a clunking sound which appears to eminate from the boot area/ rear of the vehicle, the net implies it is a damaged drop link but I am unclear of its location and cannot find any diagrams on the net or even if they have them on the rear.
I know they are on the front and are a connection to the anti roll bar system and apparently it is common on cars for the bushes to fail meaning a replacement would be require, this apparently relatively easy to do if you know where they are.
Any help would be much appreciated.

I had a similar clunk and found it to be the false boot floor on mine. I had put a few things underneath it and it was raised just enough to clunk over bumps.

I've also heard of a similar clunking sound which emanates from the sliding doors.

Hope this might be of help.

p.s. similar clunks could come from a loose lock on the rear hatch or maybe a loose exhaust.

I had a knocking at rear and found it was the rear door top mount near roof..the rubber grommet had broken apart allowing the pin to knock in the housing..I found a cure that cost nothing..I used the base from a tubeless valve used in car wheels..this sits on the pin and has cured my doors..hope this helps

i used to be indecisive..now im not too sure

I know it sounds a bit crazy, but! Our BMax does this from time to time. And I have deduced, correctly, that it is to do with the fuel! It depends on the "slosh" of the fuel in the tank. I haven't gone into the baffles in the tank of newer fords, not just the bmax, but our Kuga has a tendancy to do it too.
Check the fuel level, bumps and speed your doing.

1.6 tdci, remapped to 120 bhp, Panther Black Titanium with rear view camera, nav pac and front sensors. Always willing to stop & help in any situation I can. Karma is a beautiful thing.
