    Dropping rear subframe

    I'm in the midst of swapping my rear end to disc brakes and redoing my bushings. Any ways I got all my shit disconnected and my subframe won't budge I've been prying at it for like an hour. I have the trailing arms in a compressed state so they don't bind the subframe drive shaft is out I've heated bushings up etc. Bitch still won't drop

    I bet you're close man, hit those bushings with some more heat, they are pretty resistant even to direct flame.

    You might be able to take the weight of the car, or a big sludge hammer to knock the subframe studs loose.

      You can knock the subframe studs up into the cabin, that makes things much easier.

            Sounds like the aluminum collars on the inside of the bushing are stuck in the car. You need to drill them out from the bottom up until the collar isnt attached to the bushing.

              Heat those bushings for a good while, it takes a while for them to even start smoking, I probably take about 15-20 minutes with a propane torch to actually get they the bushing enough to actually break them apart (this depends on how worn they are). The aluminum sleeves will be stuck in the body of the car. Break them off with your favorite sledge, then drill them as shown in the picture and then you'll be able to chisel the piece out of the car by breaking it into 2 pieces

                Get a tap and thread a bolt into the sleeve. Then hammer down with the biggest slege from in the back seat.

                I had the same issue, still did this and it still wouldn't budge. I let the rear subframe weight suspend from the corroded mounts- waited a few days and BOOM- popped out by itself from the weight of everything. Make sure you at least have something to catch the subframe if it does fall in the middle of the night

                    I've heard that they like to drive you to the point of blowing your brains out, then they get tired and just fall off the car.

                    On my cabrio the bolts go in to an enclosed body cavity (puns allowed) so you have to pull the subframe with them in place. In my case I pushed the bolts up 3/4 of the way then ran a 5/8 tap in the bushing. Threaded rod and the business end of an Autozone slide hammer did it in 2minutes/sides.....but only after I had loaded the .38

                      That is what worked for me. Couple good whacks and it dropped right out.

                        You don't even need a tap. Just user a lag bolt with a tapered tip. It will cut it's own threads in the soft aluminum.
