Torching out the bushings is the easiest method I have found, a hand held propane/map gas torch is all you need.

You will need to make note/mark the alignment washers front and rear on the lower A-arms, so you can get the alignment close enough to get to a shop.

You will have to count the number of turns or the number of threads on the torsion bars to be able to set them back to the right height. You should also pick up/order 1 new torsion bolt from the dealer, before you start. They can/do break, even when not rusty.

You have to reuse the oem washers and sleeves, so don't tear them up trying to get them off/out of the bushings.

Once you get the bushings re-assembled, if you freeze them overnight, they are far easier to press back into the A-arms, I didn't need a press, just a large bench vise and some large sockets.

If this is your DD, I would recommend doing the lowers one weekend and the uppers another, or over a long 3day weekend, it is very time consuming.
