XKR rear knocking

XKR rear knocking
I have a 2002 XKR which is making a variety of noises at the back - from a low level rattling like a loose exhaust (its not) and a scraping/louder bump like a broken shock absorber.
A local garage and can't find anything obvious, they thought it was due to un-greased UVs on the driveshafts.
Could it be the subframe bushes?
Any help/advice most welcome.

Provided you've absolutely eliminated silencers (rubber mountings / loose baffles) and shock absorbers, a regular wear item is the A Frame Bushes (RH circled in red):
As your are in the UK, there's a number of sources for exchange A Frames complete with new bushes fitted.

My XK8 has a terrible rattle from the rear end on rough roads, it was so loud it was embarrasing. I rebuilt the rear suspension including new springs and bushes etc, checked the exhaust system, parking brake cables, body fixings. Nothing fixed it and it was driving me crazy. Then I noticed the rattle stopped when braking slightly, and driving along with one foot on the brake and the other on the accelerator proved it.....
My brake pads were rattling in the calipers, because they are supposed to have a spring clip on the inboard pad that located inside the brake piston. I only noticed this after seeing a diagram of XK8 pads showing the spring. New correct type pads with spring clips fixed my rattle, but at least I now know that I have a good rebuilt rear end.
Maybe the noise from duff bushes would be more of a knock than a rattle.

Knocking update
We found out yesterday that the wheel refurbishment person had put the wheels on back to front so the front wheels were on the rear and being narrower were catching on the bodywork when going over rough roads! We were lucky not to have been injured as the tyres were 5 mms from catching on the A frame.
They are now back where they should be so the big noise has gone leaving me with the original rattle.
Thanks for all your advice. I'm getting new A frame bushes, new tracking bolt assemblies and hopefully lower shock absorber bushes and I'll also check the brake pads.
At least we are narrowing down the issue, will keep you posted!

Knocking update
Just thought I'd update you on progress. I had the a-frame and lower shock absorber bushes replaced along with the toe-ing adjustment bolts either side. No joy.
Now ordered two new adaptive shock absorbers as the noise seems to be coming from inside both rear shocks (and there is a slight clicking on the drivers side front - but that can wait)
Then had all four wheels aligned.
In the meantime the engine management light came on the dash - once checked there was no problem, and now I have a low coolant light on, but I don't have low coolant.
I thought only Italian super cars were this fragile!

Solved - probably...
Just thought to update this thread. We changed the adaptive shocks (bought from David Manners in the West Mids at a very good price) and the rattle has gone.
The low coolant light was fixed by taking off the expansion tank and loosening the float inside.
I also learned how to reset the windows if they don't rise and fall as they should when you open and close the doors. With the ignition on, press both switches at the same time so the windows go fully down - you'll hear a click, then close them holding both switches together until they get to the top - you'll hear another click.
Two jobs to do - fix a slow air leak in the offside rear wheel - a new BBS valve needed, then I'll have the drivers seat out for refurbishment.
Its a real pleasure to own this car despite the work needed and sometimes feeling that one thing follows another! On a 200 + mile run on Sunday in the sunshine, plenty of admiring looks (and one wave) and nearly 25 mpg average!
