Anybody know if you need some special tool to get the rear inner control arm bushings out and reinstalled?

a press works if you take the control arm off the car, otherwise you need some sort of bushing press tool

a ball joint press may work

I used a floor press

On a W126, I used a "press" made from all-thread rod, nuts, washers, and extra-large 3/4"drive sockets. I know the rear bushings are a little different on the W140 but it might work. Just passing on an idea.

FWIW, I took one off and found that the spring perch had rusted through, though not badly. I decided to replace them and got two salvage LCAs for $50. They reputedly had come off an 80K w140. They came with the bushings and look pristine as do the arms themselves. Much easier!

Also, for what it's worth, the STAR manual says to the replace the springs by unbolting the inner bushing. I don't know why they say to do it that way, but it works immeasurably easier if you unbolt the outer bushing and lower the LCA that way. It's not the unbolting that's easier, it's the reinstallation—especially if you don't have a lift.
