I wanted to make a comment on the rear upper shock bolts. First off, I am a nub to the xj thing. I bought one to lift and trail ride and just beat around in. Thanks for all the great info here, saved me lots of time and money already. Anyway back to the rear shock bolts, I broke 3 out of 4 just like everyone here guaranteed would happen. Drilled one out to get a ez out in it, major knuckle buster when it broke.. Do not even try it, just knock out the spot welded backing nut like everyone said do. It is much easier to work on this if the leafs are not installed. A great tip to get new bolts/studs in place: Take fishing line, make a slip knot and put a small piece of plastic on it and stuff it up in the hole where you need the new bolt/stud. Take the air compressor and put a little shot of air in the same hole....presto the plastic catches the air and pulls the fishing line thru the subframe where you a can reach it easily. Put the slip knot over the very end of the bolt and simply pull it into the hole. Yes, you can reach in there with a wrench and hold the bolt head while tightening the nut. This took about 10 minutes for each side. DO NOT cut holes in the carge area, it is just not the best way to do this. :shhh:
