I've been chasing down and fixing noises, clunks and clicks on my 2000 XJ.

Well, this morning I was going through one of my standard 'how does everything look' checks on the vehicle. For some unknown reason I grabbed the bolt on the passenger side motor mount. It was finger tight.

I had never touched those before. Well, I tightened it down, went for a spin, and my clunks are gone. I still have a few 'clicks' from the worn bushings on the control arms, but for crying out loud! Such simple fix.

 

you got lucky that you found that. Those bolts LOVE to snap off when loose. Ask me how i know.

 

Same thing happened to me and I thought it was a tooth chipped off of my ring gear or my locker because it thumped and clunked under anload going up a hill.17.00 at Autozone.Glad you found it!
