Re: WJ Issues
Well it does make sense I had talked to my friend and he said he jacked his
WJ by the pumpkin all the time. I told him about the replays on the
newsgroup. He was kinda pissed that he may have caused the damage. I guess
that is why jacking points are specified in the O&M. I was wondering if
damage can be done by jacking the tube near the wheel? The TJ shows the
jacking points to be on the tubes.

If I have to jack on the tubes it's usually directly under the shock mounts,
or as close as I can get, so as to put the most force directly up and on the
suspension.
Got to agree it was hard for me not to jack from the diff. Did it all the time
in my old chevy. It was a dealership mechanic that warned me of jacking under
the diff when I was in there for some warranty work.
My solution was to get a 3ton floor lift. Just using the frame points it can
bring the wheels a good 6" off the ground.
The only time I have jacked under the diff was to raise/lower the axle for
some suspension work. And then it was just the axles weight. The ZJ was up
on jack stands.
