The new driveshaft rubber support just forces on after the driveshaft is
disconnected in the center.  If you're changing the bearing too, a press
is a good idea.
The rear shocks just unbolt easily, the axle needs to be supported as
they stop it from drooping too far.  The only problem that crops up is
(very common in my climate) the lower bolts seizing in the shock and
spacer bushing inside the trailing arm.
