Rear clunking. Is it this?

[geraintthomas]

I know, I know, there's lots of threads about this and I'm aware of that. I just like to ask a question. I have a clunking from both sides on the rear, as if both sides have a part that's loose or worn out. Over rough roads I can hear it, not so much on motorway speeds (if at all).

I'm guessing it's probably the upper control arms.

I know it's very hard to diagnose these, so that's fine. But I'd like to rule out everything else before forking out a lot of money on two new arms.

So from looking at this photo, I'd like to ask for some help:


- The upper control arms are probably the culprit, but I've noticed the lower control arms and toe arms; would these knock at all? Or is it very unlikely?

- It COULD be drop links, but how do I check the condition of the drop links, in case these are the culprit?

Thanks for the help I just want to make sure I can check everything I can before buying two new arms.
