Open Door when the Z is on a Jack?

While perusing a few other Z sites, every once in a while I'll see a Z on a jack with a door or both doors open. I've always been under the impression that's not a good idea with a unibody car. Whether using the standard issue Datsun jack or even a regular floor jack.

True, False

Ramps and lifts are different, all 4 wheels are still on a solid surface. For example when you've got the Z up on a Datsun jack to change a tire or something. Better explained maybe would be when only 3 wheels are on the ground, even just 2. Seems there would be a little stress on the body.

Hi Zrush!

Having the car supported equally on jack stands and jacking it up on one side are two different things. It is not such a great idea to open the door on the jacked side during the operation. It's not a big deal, but yea, the car is stressed unequally and keeping the dorr closed helps. Try it. You'll notice the door doesn't open or close as well.

I have noticed the same thing, the door didn't want to close easily. I haven't put the doors on since that, I'm guessing that they'll be fine.

there is no problem with open doors on a car when its jacked or on a hoist . chassis are not designed with doors as a load bearing item although difficulty opening and closing them while the car is lifted may happen as soon as the car is on the ground all is well. i am a auto technition by trade and went to school for chassis fabrication . note that on badly rusted vehicles the doors may have become load bearing , but at that point finding another car would be in your best intrest.

My Z was up for 6 years and the only thing I can see wrong is the front driver side strut is maxed out. My "opinion" is: I don't think the doors would have much of an effect on the frame as fas as "twisting" it. It would, however, effect the weight distributed when the car is in the air/ on jacks or on a lift, but not by much.
