Default Does jacking up car affect suspension/alignment??

Lets say you are lifting it up 1 wheel at a time. Does this affect the cars alignment at all? Or flex the chasis?

I shouldn't affect the alignment when you put it back down and let the suspension settle. The chassis will surely flex when one wheel is lifted, but that won't do any harm to the car.

Sure - lifting each side can affect that corner because of the weight of the wheel/tire and suspension . . but it'll return to normal upon driving . . the chassis does not flex like the old Corvettes did . .I remember having to open the doors on my C3's so they wouldn't bind up when it was lifted although I'm not sure that wasn't more mistique than fact.

Is there an underlying issue you're trying to address?? A few more details might help . . .

If I may tag along with the original question....I want to jack the vette one rear wheel at a time using a floor jack. Is the best jacking point at the nearest puck or behind the wheel per the manual. I don't think I have seen anything addressing lifting one corner at a time.

Thank you.......

If your jacking one wheel at a time use the jacking puck for that quarter to lift it up the car a few inches for tire removal. If you are raising it higher than a few inches then the whole rear or front should be lifted from the recomended jacking points under the chasis and then supported on both sides with jack stands and pucks.

There's nothing wrong with lifting one wheel/corner at a time but you'd be better off buying and using an adaptor beam to use with a floor jack. With an adaptor beam you can lift using the preferred lifting points and you'll be able to lift the front or rear at once. Lifting one corner is IMO best done using pucks but if you're careful it can be done without pucks and without damaging the car.

Here's a somewhat related thread that may help:

personally, I wouldn't jack the car up on a body mount just to lift one wheel off the ground. This means it requires you to unload the full suspension before the wheel gets off the ground. You could possibly have to raise that one corner of the car a good 6" or more before the wheel comes off the ground. In cases like this I always raise the one corner by the lower control arm or something sufficient right behind the wheel. I just put a piece of wood between the jack and the contact point. This allows the suspension to stay loaded which dramatically decreases the height you need to raise it before the wheel comes off the ground.
