Well Jim,
This is one of the first jobs I had to do on my car when I bought it
back
in 1987 (along with replacing the shock mounts and inner rear fenders).
If
you like to work on your car then this is the job for you! You have to
remove the wheels, the brakes, and then pull the hubs apart (special
tool
is required for this which I can loan to you or you can purchase a new
design one from someone on the NASS list). The axles and stub axles
have
to be separated from the donut also.
There are tools shown in the Bently manual that hold the rear of the car
up
using the spring and I highly suggest fabricating these also. When it
goes
back together you keep the straps on the donuts in place until the job
is
finished. Cut the straps last. Note that this would be a good winter
project.
You might as well replace all the suspension bushings and hardware while
you are at it because you will not want to go back and do it again
later!
The lower pivots for the A arm on the vertical link tend to fuse (bolt
seizes to the steel spacers). When I did mine I replaced the steel
spacers
with bronze bushings.
The other issue at this point in time is the availability of quality
rubber
donuts. The good ones were manufactured by or were called "Metallastic"
or
something like that and are no longer available as I understand it.
There
are people replacing these donuts with CV joints but this is a big
undertaking.

Yes, a big undertaking, but in my opinion, one well worth doing. Once
the CV Joints are installed, they are practically bulletproof. However,
if you do need to replace them, it is much easier than replacing
Rotoflex couplers because there is a lot of lateral slack in the CV
Joints and you don't have to deal with the flex of the coupler. Plus,
you don't have to remove the hubs in order to change out the couplers.
