Hello all!
I'm in Australia and am a keen XJ40 owner Have also been a longstanding 420 owner. Have had a few electrical adventures with both. Now have a clunk in the rear offside of the XJ40 that I'm planning to tackle. You still around Webserve (my optimistic friend "should only take minute or two..."!)?
Well I might not be Clark, but I do know you need to check your dampeners.
First inspect your exhaust for looseness, then proceed to inspect your dampeners for leaks, and worn end-bushings. I personally had a shock with an internal problem that would make a "Thud" on fast dips. I replaced the shocks and the noise vanished.
