Dumb question of the day

Hi folks. I have a 72 Camaro, I'm fixing to do a restore on. What I was curious about is, I have a 2 post lift. I want to pull the front subframe, and tear it down to be powdercoated, and to rebuild the suspension. if I use my lift, will I have to worry about after the front end comes off, will it be heavier, on the rear end enough to fall off the lift? Thanks in advance...Randy

That is a possibility so what is done is to make or buy some really tall jackstands to provide addititional support while you are working on something like that..

What I would do is, lift the car and get the bolts most of the way out....Lower it and reposition just to lift the body off. Remove the bolts on the ground and lift the body.

A freind and I did this to a 83 elcomino. we had most of the frame bolts out or loose than set it back on floor and set the lift up to lift the body. Removed the rest of the bolts while on the floor than just lifted the body and rolled the frame out from under it. worked great as we were taking body to the scrap. Backed the rollback in under it and set it down. Used the frame for a 46 ford 4dr.

I doubt you'll drop the subframe while the car is up in the air on a lift. How would you support the subframe when it's high enough to stand under it, and not have it drop 6'-7'? Most likely you'll get it up and break things loose, then lower it down near the ground to drop it.
If you leave the rear tires and wheels on it you can put ramps under the tires and lower it until the tires are supported on the ramps. Then you can get under the car and drop the subframe and the body wont go anywhere. Once that is done you can make a support frame to bolt to the firewall holes that the front fenders bolt into that will support the front. That will allow you to drop the lift and relocate the main body so you can lift it and remove the rear axle and springs.

I think I saw this in one of the clips for the new season of Car Warriors; they are removing a front subframe and as they do the back of the car falls down.

You can bet that if you position a two point lift near the center of a car; it will fall off the back when you remove the front subframe. The center of gravity shifts drastically when you remove the weight of the front subframe (more so if the engine/trans are removed with it).

The good news is that by thinking ahead with proper jacks to support the rear, you can avoid this problem.

Also, I agree with the idea that keeping everything as low as you can is the way to go. Also, you don't want to be under either the subframe or the car when you remove the last of the bolts.

At the dealership we would put a 1 inch ratchet strap from the front lift arm to the door striker on both sides. Also, we did pull engines and sub frames out with the car 7 feet in the air. Newer vehicles mandate this approach. We used an electric lift table or a modified engine hoist that would hold the engine and trans from underneath.

true but the diffence is, when you take the cradle out, you still have 500 lb on the nose end..
the 2nd gen f body.(70-81). it's zero lb on that end..
on these cars, you'd be on the front of the rear frame rail.. and the front would be on the floor boards or rocker lip..
you'd have to put it on the lift so the rear arms are under the rear frame rails inter the trunk.. and the fronts under the rocker or floor boards.. BOTH not made to lift these cars.. with the whole nose/engine/tranny still in the subframe.. safer on jackstands, and then lift the body..
you could strap the car down around the whole cowl to the front lift arms, but you're still lifting the car with the rockers and/or floor boards..
sorry not me..
cars are high enough to unbolt it with the rear tires on the ground and jack stands, or blocks under the cowl area.. untill the subframe is moved, then lift it.. use'n the subframe bolt area(strong) for the front arms

Thanks for all the answers. I'm probably just going to lift it high enough to unbolt it, then work from there.
