Doug,

Do you know if the D35 or 8.25 can be damaged this way?

I lift by the pumpkin all the time, without issue. However, in
exchanging wheels or rotating, I tend to lift one side up at a time via
the middle of the frame rail.

Just be warned that you habit might come back and bite you big time if
you use the pumpkin on some newer vehicles for a jack point. They made
them weaker to save weight or as a planned obsolescence feature. Weaken
the drive parts on a SUV, right.... Complete rear ends are expensive.

Second, just how freaking big is your floor jack that you can jack a TJ
up from the side frame rails and actually lift the tires off the ground?????

I can't even lift my XJ that way, nor are the 'frame' rails on my XJ
strong enough to jack from. The owners manual for the XJ says to use
the axle tubes...

Well, they don't come off the ground much, but all you need is a half
inch. Another system I have for rotating, only requires one wheel off
the ground at a time. Remove the spare from the back... then jack up the
RR only and replace w/ spare, roll RR to RF, RF to LR and LR to LF...LF
to spare. All one corner at a time. Easier to be happy with the jack
point but takes a just a few mins longer and a bit more scrambling
around. I use the control arm perches, again without issue. If you're
lifting a corner of your Jeep and bending axle tubes, you've got more
problems than needing a tire rotation. To replace the wheels completely,
I'd be inclined to do one side at a time.
