Shown below is an updated version of a prior post I made where I tried to make the distinction between "lift" and "jack" points. I have had the car up in the air a couple of times with all 4 wheels off the ground using this procedure.


Over the weekend I took all 4 wheels off to clean them up for KC (as suggested by Turbo). At the rear of the car, the lifting instructions (linked in another post) identify rear jack points where the suspension linkages are attached to the frame cross member. The jack slides in easily from the rear and I placed it under one of the suspension linkage frames and jacked up the rear end. Be careful to not place the jack under the suspension linkage as you can lift the linkage while lifting the car. Jacking at one side will lift the rear of the car so both wheels are off the ground. You can then place jack stands under both rear lifting points using a single jack.

The rear lifting points are easy to find with the slots in the frame and the recessed area in the body panel. I tried to purchase the GM lift pads from my dealer, but I was told that I could not buy service tools. I went the build your own route and purchased 1 ¼ inch OD screw eyes that were inserted into wood blocks. The wood block is 2 x 4 stock cut down to 2 ½ inch wide x 3 inches long. You screw the eye into the center of the block and the block sits inside the body when twisted into the frame rail. (Some Corvette sites talk about using hockey pucks with screw eyes.) The jack stands interface with the lift pad and you can safely work on your car and not worry about bending the body.

The lifting instructions identify front jack points where the front suspension linkages are attached to the frame cross member. There was room for my jack to fit in between the air-dam and front tire, into and under the lift point. Again, be careful not to lift by the suspension linkage. If the rear end has been placed on the rear jack stands as described above, jacking on one front jack point will lift both front wheels off the ground allowing you to place 2 jack stands under the front lifting points. (When I tried to lift the front end first, the suspension allowed the car flex and I could only lift one side of the front.)

The front frame slot does not have a body panel recess which leads me to think that it is not the front lift point. I remember something about this being a tie down location for shipping.

My interpretation of the lifting instructions is that the front lifting point is located between the front frame slot and front wheel on an auxiliary frame pad that has two circles punched in it. This auxiliary frame appears connected to the main frame rail as it moves in from the front frame slot, in to the engine/front suspension mounting.

This link http://www.corvettegarage.com/produc...-corvette.html should take you to a site with some anodized aluminum jack pads. They look nice but I decided to spend the money on other tools.

Good luck with the tire change overs.
