For the most part they all are. Car makers have cut weight where
they can and that has created weaknesses in what used to be your basic
hunk of iron. Now diffs are aluminum and the tubes are thinner.
It's just not a good idea to ever jack from the pumpkin. They make
trusses to strengthen axles for larger tires and off road bumps.
Some bolt, some weld.

Hi Ed,
Another Chrysler f**ked up. They assembled the ZJ Dana 44 using

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.
