I was replacing the control arms on my 98 ZJ yesterday and I ran into a bit of a snag. I got all of them done except the rear uppers. When I went to remove the bolts holding the rear end of the rear upper control arms I could not withdraw them because of interference from the rear bumpstops. When I looked at the bumpstops I could not figure out how to remove them. I checked the FSM but they are not even mentioned. As always, your help and suggestions are appreciated.
