Default Jacking C3

I am a newbie to the corvette world and this may seem like a stupid question. Where do I place the floor jack under the car to raise the front end? i have looked on line and have had no luck finding anything on it. Where is the best place to place jack stands.? Thanks in advance.

On the side of the car between the wheels is the chassis rails you can jack on these do not jack on the front cross member

Not to sound stuoid, but do you mean the raile between the front and rear tires?

I position my front jack stands further forward toward the front as most of the weight is on the front end and it can cause stress on the front clip to have all the weight bearing down.










EDIT: I jack one side up at a time to the point where I can fit the two stands under at there lowest point, then I do the other side. At that stage if I need it higher I will repeat the process. I like to do it like this rather than tipping the car on too much of an angle while jacking it up.

I took a picture of the “Jacking Instructions” sticker on the inside of the door of the storage compartment of my 82 and attached it to this message for your reading enjoyment. I am not sure if different years have different techniques.



I agree with Lachymac1 and not twisting the frame by jacking from one point only. I use two jacks on the same side simultaneously in the GM specified locations.

No mention of loosening the t-tops on this label, however.

Those jacking instructions are used for changing a tire, typically when out and about and or getting flat. During those situations it is common to jack up the car where you need to change the tire. For jacking up the car to put on jack stands, which you also have to be very careful about where they are placed and what quality are the jack stands, I do the two jacks on the side method. There is a plate now for the front cross member that allows you to jack up the car front end from a single spot and it works great, I developed it for just that purpose. The front cross member is far too thin to jack up the car with the engine and transmission in place but the addition of support up front makes it a breeze. Just be safe with your jack placement and slide a tire under the car in case the jacks fail or the car shifts. Be safe.

David,
I've read in other post that you were once marketing these. Are you still? If not, where can I find one.
TIA

Russ, you can write to me at AllVettes4Me@gmail.com if you would like more information on the jacking skid plates. I don't want to hijack the OP posting question here but I do appreciate the question. Thank you. David

New at this too, on my 81, opened doors, and t tops then proceeded to jack equally on each side near rear. Is it normal that the tires really sag a bunch?! Tires came off the ground only about 1/2 inch then got nervous and slowly put it down again. Could my spring be bad and or shocks? Want to remove the tires so I can put Eastwood rust coating on frame, will want to do the same with front tires. Thanks for the help!

Yes, the tires will "sag" to the bottom of suspension travel because it's no longer bearing weight. Also the bottom of the rear tires will move inwards quite noticeably.

It was mentioned at least once before but very much worth repeating that you should NOT leave the car up on jack stands installed between the wheels for any but a short time. That long heavy front end will cause the frame to bend ever so slightly over the jack stands behind the front wheel. This is a VERY common cause of gaps at the front of the door that get larger as they go up. If you're going to keep it up for any length of time support the front via the jack stand positions in the nose.

Is it better to just jack up one side at a time , right front and right rear offf the ground, and take care of details, then do the opposite side?

They're not cheap but sometimes on sale at Costco. Quick Jack lifts the entire car equally from both side frame rails.
Great for DYIers. No saggy frame.

Dude, everybody was being cool and helpful to the new guy and then you showed up...not cool. The guy is being serious about safety when jacking up his car. Yes, he could do a search but just perhaps he had some questions and needed to clarify. Not everyone was born with a wrench in their hand or had someone in their life to teach them. I'm thrilled to see new guys/gals wrenching on these cars. Ask more questions, new guy!

2Tone,

Go easy on L46man. It appears to me that he was replying to TRT SR in the post immediately prior to the post you quoted. However, I think L46-man mistakenly quoted the "new guy" VinnyPG's original post.
