Jacking point under diff?
Is this a terrible thing to do? It's a heck of a lot more convenient than using a jack on each side and going back and forth. I placed the jack under the cross member beneath the differential. It seemed to work fine. Just wondering if this is a no-no. Thanks
Of course I used jack stands after it was up.

is the exhaust in the way that you cant jack it by the spring mounting plate?

I come in from the rear....and not from the side (but that is just me)....and depending on the exhaust...I will catch the plate for the rear leaf spring.
What is 'NASCAR' style????

Jack up the entire side of the car midships where the crossmember is and then place your jacks fore and aft under the frame. Do the same for the other side. This is assuming your using a floor jack on wheels.

I don't care who you are that is funny. (but maybe that is just my sense of humor)

It's easier to jack it up NASCAR style. It will not damage anything if your frame is solid.

Jack up drivers side, place jack stands. Jack up passenger side, place jack stands. Done.

I say its still quicker to jack up from the side even if your only using rear or front jacks. Shouldn't take more than two minutes for both sides.

I usually try to 'catch' what I write and make sure it can not be interpreted 'differently'. I completely missed that one.....
Heck...I read it again and it made me laugh.
Back to the post.
I have wood ramps that I can drive on that will raise the car 2 inches so I can slide my floor jack under it. Also..my floor jack has a very low saddle so I can get under a car very well....which makes a HUGE difference...and the saddle has teeth that are raised up more so they can catch on things to secure it when I am jacking.
I am not judging how person chooses to jack up their Corvette...But I have SEEN the effects of jacking it up on one side and then doing the other side and it has EVERYTHING on the angle of the frame and where it is contacting the jack stand...and THEN when you raise the other side....how well the floor jack can roll so the frame does not slide or want to push the jack stand due to how the floor jack is moving during it being raised.
I will stick with my method and those who do it differently....if you are happy with it and successful...I guess that is all that matters.

Reading this thread, made me thank God, I picked up one of these for our little private shop! I was so sick of jacking up the car and putting jack stands on it. It was one of the biggest PITA's, that I was glad to get rid of! Well worth the $1,500 I paid for it.

Something like this in case you were wondering what I was referring to. Just an example.

TRUST ME...My method does NOT take all day. NOT even close...maybe 5 minutes to do all four wheels and jack stands if I had to guess. I do not time myself in how fast I can get it safely jacked up and supported. That is much like me trying to go super fast and beat the time given by an insurance company for 'set-up and measure' when setting up a car on a frame machine. I am MORE WORRIED that I have it correctly locked down so when I do pulls on it...it does what I want it to do. I guess it all depends on the person and how they choose to to do 'whatever' it is that they are doing.
Like I wrote...I AM NOT judging ANYBODY on how they do whatever it is they do. I do not have to warranty THEIR work.
I am just passing along my method so that there is an option. AND...just like you. I just feel my method seems to fit me better so I do not have to explain a problem to the customer in the side wall of a tire due to jacking it up from the side and having a problem,...or slipping off the stands...or causing the jack stands to tilt due to how the frame did not want to adjust on the jack stand correctly when being lifted from the other side.
You have your way that works for you...I have mine. I have no problem with that.

Nice lift....and it is a time saver ...that is for sure....unless you have not acquired them yet...I would get two of the safety stands that you can install under the car when it is up on the lift. And to prove my point...when you begin to get the wheels off the ground...WATCH the door gap at the front end by the windshield area ans see if it widens when the wheels lift off the ground.....this is allowing all the weight of the engine/radiator/suspension that is hanging out past where your supports for your lift are located on the frame and this 'hanging' of the front clip will begin to fatigue this area at the windshield cowl...and it will get a bit worse each and every time the car is lifted and allowed to hang. The severity of the gap widening is what it is. Yours may be good..but if you are aware of this and one day notice that it seems to get wider....then hopefully what I just wrote makes sense and that I am not just being overly paranoid. 'Just saying'.
