That was a good video. Unfortunately, his method isn't very easy. I'll bet it took him forever to do that.

Subframe bushing removal

I like his videos a lot but that wouldn't of worked on mine on one side.
It is a lot of work to drop the exhaust, drive shaft etc. I ended up removing the half shafts and then the diff but i needed to replace the splitter for the rear brakes and the short brake lines up high.
No way to get at those or the trailing arm bushings either.
BTW, that differential weighs a ton

Maybe a better way of doing this is a combination of methods: Loosen the bushings from the frame by threading a lag bolt into the bushing from below and then beating on it from above. Once the subframe is loose from the frame, it would be real easy to use his method to pull the bushings out without dropping the subframe.

Heat the subframe around the bushing before using the extractor tools. Not too much, just until you see the bushing start smoking. It breaks the bond between the rubber outside of the bushing and the subframe enough that they usually just slide out like nothing, but not too much to where you're left with a bunch of sticky melted rubber inside the subframe.Byron

I think there are pics in my build thread but from memory, I used a combination of a puller with the ears ground shorter and threaded rod. I preloaded the bearing then gently heated the outer case of the subframe and the bushing just kind of slithered out :)Seat Shocks....I have passed the baton to John Christy from Ninestitch.

The differential weighs a ton, and it can be unmounted independently.
The brake rotors are also heavy.

Yes, the DS will likely foul on the subframe when you lower the assembly. Also, removing it in one piece can be a bit violent, but not really dangerous since most of us put a jack or something similar in place while we remove the nuts from the studs. Normally the assy does fall over, so some wood or a couple of pallets can be helpful to prevent damage.
I never seem to be able to remove the e brake lines from the tubes, so I typically have to remove the cables from the TAs, which is a hassle.

Once everything is loose, then slowly undo the last nuts and slowly lower the jack. The key is to be careful and adjust as needed, don't pry on stuff with everything disconnected or it's going to come apart violently.sigpic
