Just got done replace the subframe/diff bushings and had to disconnect the rear breaks lines to get the subframe out. Do I need to bleed the front brakes as well? I tried just bleeding the rear brakes but the pedal is still hitting the floor.

May have some air in the ABS unit.

I have replaced the mc and never gotten air in the abs. Bleed all of them, they run in two circuits so if something happens to one there is still the other.

Did you let all of the fluid leak out of the lines, or caped them as soon as they were opened ?

I did not cap it off.

Don't do that. Did the master cylinder still have fluid in it when you were done with the other work?

very little if any. I am going to try to bleed all 4 today using the pump brake method. If that doesn't work I am going to go get a pressure bleeder.

Ive been trying to pull fluid from the rear with my snap on bleeder and got nothing so far. I got the fronts to bleed just fine but the rears are being jerks.

Try this. I opened the bleeder before i went in the house last night, at the shop now. Presto fluid in the floor

You've got air in the ABS modules. You will need a tech 2 (or clone) to cycle the abs module to get a proper bleed:

Something like this:

Pumping break method worked!!! I just had to bleed the rear breaks. I'll remember to cap off the lines in the future.
