Exactly what the above poster said. It was one of the biggest beatings I've taken with this jeep. They are all incredibly difficult to cut out, and you will almost certainly have to cut them out. I put kroil and pb blaster on them for over a week straight and still broke all but a couple when I tried to back the nuts off the bolts. Ended up having to weld up a few new mounts and had to drill a couple of holes on the floor board to reach a couple of them.
Made a HUGE difference in the ride quality, though, and was inexpensive, albeit time consuming.
