Front suspension- running out of bits to replace!

Front suspension- running out of bits to replace!
Hi again Folks
I've been hunting noisy gremlins in the front suspension of my 03 XKR convertible. So far have changed:
Upper and lower shock mounts both sides
Sway bar bushes.
Sway bar drop links
Upper control arm bushes (ball joints were ok)
Lower control arm bushes and ball joints
Driver side only CATS shock.
I'm STILL getting a chatter from the passengers side which turns into a loud knock when it encounters a pot hole or similar obstacle.
By elimination does it have to be the very expensive CATS shock on the passengers side or is there something else that may be the culprit ?
All opinions would be welcome .
Thanks Jeff

Two things worth double-checking.
1. Is the nut on top of the shock absorber (inside the engine bay) very tight ? It's not always easy to keep the threaded part from turning while getting the nut to the correct torque. You will get a knocking noise if it is even a tiny bit loose.
2. Check the front ends of the "X braces" - see here :

I for one would like to know what causes my similar clunk in the right side suspension. I've "narrowed" it down to upper ball joint, lower ball joint, lower arm bushings, sway bar bushings, motor mount, inner steering rack, outer tie rod, or shock absorber internals. Let us know how you fixed it.

Thanks. I changed the bottom ball joints and 2 garages have told me the upper ones seem fine. I also had both the calipers and disks off while trying to get the lower control arms off so I know they're ok. Just desperately don't want to spend $700 on a new adaptive shock and find that still doesn't fix it...!

So have checked the nut on the top of the adaptive shock and itis set at the correct torque.
The X braces are fine. Don't think it would be bump stops as noise happen under light to medium road bumps no where near full suspension travel.
So I'm guess all that's left is upper ball joint, adaptive shock or front cradle V mounts (whatever they are..).
Shock is not leaking or anything. I had a Euro car specialist go thru front suspension and all he could fault were lower control arm bushes and bj's all of which have now been replaced.
Last thoughts anybody?
Thanks Jeff

Or you could replace the expensive shocks with XK8 shocks. I've changed mounts on both and the shocks I'm sure will interchange. Do we really need the adaptive feature? I've had both and can't remember much difference. However I don't thrash on my cars either. Good luck.
