Put a couple hundred miles on the xjr recently and the noise has gotten even louder so I'll be investigating today but I'm leaning towards the front lower arms as that is the most likely culprit considering I've just about replaced everything else haha, I'll be buying a set from BRUTAL if I discover that is my issue.
Thanks again

For now, I have the stabilizer bushings on order. I disconnected both end links and the bar seems to be tat loose. It hardly justifies the clunking noise but it is my starting point.

Sorry for the delay in response.... My XJR was totaled before I could sort out the clunk so I am sorry to say I wont be able to help you but based on your description it sounds like you need to replace those front lower arm bushings or arms

I have read threads in this forum that suggest many have just replaced the bushings at a considerable savings. What suggestions do you all have. Complete replacement or just the bushings. It appears that removing the lower control arm is pretty straight forward without the need for special tools. This car is not a daily driver and can remain out of use for any period of time. Thanks.
Additional, in the past when repairing cars I have owned, I would check out a Chilton repair manual. Is there a repair manual which covers these XJ XJR models? Thanks again.
