Dropping my 1st rear subframe, what to expect??

[JustJeff]

As part of swapping my turbo vert drivetrain into a new vert I'll be dropping two rear subframes to swap differentials. I'm thinking of leaving the tires on so it's easier to move around once off. Obviously disconnect shocks, brake lines, e-brake. I've got 2 bolts on the subframe, another 2 on the diff, and the control link.

Am I missing anything. I haven't been under the car in sometime, was gonna get under the car today..what with it not raining. BUT water happens to be draining right where my engine-less car is sitting.

What's the lifespan on the rear bushings? Obviously now would be a great time to replace them. I'm not looking for any of the hardened or polyurethane bushings. From what I've read and been told it'll increase ride noise and stiffness but have minimal benefits for a city and daily driven car.

I am considering DTSS removal, but I've never driven an FC that has that removed. Experience, thoughts and opinions are appreciated.

In general what should I expect and what else or extra can I do?
