How bad is it to replace rear cross member with body on. 85 Cj7 Thanks Ed
Well, the body is mounted to it and there's welds on the top side of the frame to help hold it on...
'86 CJ-7 Laredo: 4.2,T-999,D300,D30/D44,'94 YJ tub, full cage, Shrockworks rockers, OYR corners, AC,cruise,restored seats,3 tops,2.5" Superlift,F-T shackle reversal, RS9000x's,35" Dunlop Mud Rovers.
'83 Scrambler: time & money pit under construction with parts from CJ's,YJ's,TJ's,FSJ's,GM,Ford,IH,Honda,Toyota and a whole lotta aftermarket & custom stuff.
What you should do is either remove the body to gain access OR remove the body mount bolts to place spacer blocks between the tub and frame. I would raise it at least 8 inches in the back and use all thread in two of the body mounts to keep the tub in basic alignment. E brake cable should be OK and gas tank will need to be removed of course....the shifter/tunnel cover will need to be addressed though. Rear shackles may get in the way and need to be remove to allow spring to hang down (jack stands under frame just ahead of rear spring main eye).

I've done it before with the tub on.. it was a PITA. I hacked off most of the crossmember (plasma/sawzall/air chisel) and then used an air chisel to break the weld on top of the frame.
