Any step by step to separate drivetrain from body?
Searched and didn't find one. I'm just looking for tips to help expedite. I have a 2 post lift and already have the calipers hung, upper control arms and shocks disconnected. It appears i can just unbolt and suspend the abs module (y2k so it's up front). I have had the rear cradle out so I know that the brake lines will stay w/ the body but I don't recall if the wiring has to stay of if there is a master plug under there I can unplug and just take the entire rear harness out w/ the drivetrain. Up front I think I read that I can unplug the main engine harness from the firewall or somewhere near there? What about front brake lines? I read something about having to bend them? I can wire up the AC compressor during drop also. Any gotchas i'm missing here?
Thanks much
Dave

A number of us have done this in different ways. I too used a 2-post lift.
I couldn't find a master plug for the rear wiring, but it's really not that big of a deal. Just disconnect everything you can find that goes to the drivetrain, there's really not much. The entire harness rests in clips in the torque tube, but it's really easy to slide out as you start to lift the body off.
Same with the front. I just disconnected everything from the engine (there's not that much really), and watched carefully as I lifted the body. I'd lift it a few inches, stop and check for any connected wires. I'd repeat that until everything was clear.
The front right brake line goes underneath the steering rack from the ABS controller. When you lift the body with the brake lines in tact, you'll need to get the steering rack out of the way. I took it out entirely, but you could probably just disconnect it and slide it over to the right to let the brake line clear.
It's really not a bad job at all as long as you take your time and pay close attention to what things could get caught up. I also recommend taking pictures of EVERYTHING you can before you disconnect it so you know how it goes back together later.
I know others have done it differently, but this is how I tackled it.

You can unbolt the calipers and use zip ties to hang them to the bracket on the frame where the brake lines connect to the hard lines. I would use 1 zip to circle the caliper front to back and run another through that zip tie and the bracket.
Like you I have had both subframes and the driveline out but have never lifted it all off at once. just go slow and watch for wires, lines, sensors. etc.

Make sure it’s released from the plastic clips then you just have to maneuver it to clear, it usually gets hung up on the balancer so I usually just raise the body a couple inches at a time and check everything front to rear, if you leave shifter or shifter box bolted in make sure it doesn’t hang up on the fuel lines also

on the a/c I have access to a/c machine so I removed the freon and unbolted the line on back of compressor, for the brakes I unbolted the calipers and zip tied them up, pull the rear axles from diff so the rear lines can clear, just disconnect all the coolant hose, make sure all the wiring unplugged and grounds unbolted from motor

Or are you saying you took all brake lines out w/ it? If so that's not a bad idea either if the clips are easy to get out along the way.

Thanks that is helpful. That would make sense then with people saying they bent the front line out of the way a bit, perhaps to clear the balancer. I'll have all the black clips disconnected from the front crossmember. I've had both out before so as long as I can get the motor around that front line I should be good to go.
I haven’t watched the video just giving reference from when I did mine, I’ve dropped the whole drivetrain a few times

thanks Ahrmasos, I did a quick look today and that seems the best way, sadly I already unbolted all the calipers 
Will put back on. It even seems the hard line clip to body at caliper is bolted in which is nice.

you do realize the entire driveline is coming out in one piece right? The brake lines have to stay w/ the body unless i want to bleed the system.
Or are you saying you took all brake lines out w/ it? If so that's not a bad idea either if the clips are easy to get out along the way.

They did this on Two Guys Garage, called Project C5. A quick Utube search will get you there. I think it is a three- part, if I recall correctly.
pretty cool!!
