Ha ha, have fun with those. I did sort of the same thing for the fronts except I used a hacksaw instead of a Jig. I'm too cheap for power tools. I ripped out the center sleeve, took the blade off the hacksaw, put it through, sawed a chunk out of the the out bushing shell and then just hammered it out with a screwdriver. Worked like a charm. To put the new bushings in, it's simple. Just grease the piss out of the LCA hole and the bushings and put them in a vise and push each side in. After that, grease the center sleeve and push it in.

For the rear LCA, I got tricky. I did this over at the shop so I had a press and some machines. I measured the metal outer sleeve and machined a round brass plug on the lathe to just a bit smaller and then just pushed the SOB right out. Took about 30 seconds to do each bushing. Oh yeah, the rear subframe bushing is a huge amount of fun. Good luck. Seeya.
