i have a 3 1/2 ton floor jack and with my last car could just grab the rear under the differential and 3 pumps back end of car was off the ground.
can this be done with the corvette or will it damage the rear assembly in some way?

thanks in advance

Restored the frame on my 75 this spring. Lifted the rear by the differential and set the jack stands with no problems. I would not lift the rear by the half shafts. Good luck.

I have had my Corvette for over 30 years and always lifted the rear portion of the car by the rear end housing. Have never had a problem.

excellent, thanks for the info.
getting ready to replace rear shocks and just want to
lift whole back of car in one shot.

However.......... a few years back i saw a bulletin from GM about a product called "Jackpoint". it attached to the center of the differential and had a small "platform" that stuck down whereby you could place a jack under it to lift the vehicle. GM claimed this was unwise and could result in damage to the differential housing. just a thought.

I don't lift my car by the diff, but even if you do, it might be a moot point. You aren't planning on replacing the shocks with the jack holding the car only by the diff, are you? I'd suggest jack stands...

I've got a solution to the problem:

2 post lift! Drive it on, jack it up, problem solved!

Am I the only one that uses ramps?


-Pete. KEEP DRIVING!!!

Can't use ramps if you're doing brake work, since it involves taking the tire off; can't take the shocks off if you've got pressure on the shocks.

I use ramps to change oil and radiator fluid, but I can only do that on my driveway or the street because the ramps want to slide on the smooth surface of my garage floor.

Thats what i use The side pipes force me to use custom lift points up front. I have to take off the tire and lift from under the spring.

Not sure about the back, but you do not try to jack up both front wheels using the frame. It isn't designed for that and it will buckle.
(a little)

no just want to get the whole back end off the ground in one shot
so i can set the stands and take the tires off.
besides doing shocks i walso want to adjust parking brake.
guy i bought it from did all new cables and supposedly
new brakes (i'll find out when i get it apart) and i dont believe
they were adjusted properly.
being a 4 speed i would like it to work at least a little anyway.

@ kilroy: I made this bad experience with my`73. I was wondering about thte little buckle in the traverse frame. I will never try it again. But I don`t know how is it in a service garage ...

the only problem with jacking a c3 up by the diff is the spare tire carrier can be a bit low on some cars and you cant get the jack past it

Keep in mind also that if you have original style 2>1<2 exhaust it's right under the differential. My duals on my black 79 are right under there too.

couldnt get the diff due to items mentioned above
spare tire carrier and exhaust right in the way.
ended up jacking each side and setting stands.

the shocks were shocking to say the least,
not sure but i think they were factory originals.
