[89ltd]

I had a motor mount go on my 89, before I found out I would here a clunk , kinda grinding noise , but only when taking off, not when stopping. My engine went up quite a bit more than an inch, but the mount was totally shot where yours if probably on its way, I talking about the engine mount on the drivers side. The bump and clunking noise I had one time on my chev pickup was the result of one of the rear wheels had loose lug nuts and the holes turned into slots, big clunk when ever I put on the brakes. I would also try driving down the road, put in neutral and stop with the e-brake, see if that makes a difference. I also noticed the wining when I first bought it, now a year later I'm used to it, don't really know if all jeeps do it or not.
