yeah it does feel solid and heavy, i feel it in the floor on my feet and i feel it in the seat...its only at low speeds when u go over a curbed driveway and stuff like that...or when there are numerous bumps in the road and i am going aprx 5mph and the truck rocks back and forth side to side...im goign to put it in the air tonight after work and look underneath

May sound dumb, but check to make sure that your exhaust isn't contacting on of the bolts on the rear suspension where it goes over the axle. Used to see quite a few of those on early Disco II's.

Otherwise I'd be checking the sway bar and shocks.

Get under the truck in the rear and have someone rock it while you watch your watts linkage. There, you found your problem.

I had the exact same thing a few years back. It turned out to be a loose bushing between the body and frame. Rule nothing out. Sway bar, control arm bushings, shock bushing.

My wifes 01 had a loose, drivers side, radius arm bolt.

Good luck
