Considerations while awaiting new shocks:

With car on jack stands and wheels off…..
Remove spare tire for cleaning and better access to bottom of car.
Put a few inches of hot soapy water in a bucket, and scrub the bottom of the car, transferring dirt via a thick rag, from the wheel wells and suspension into the bucket. Dump black water and refill, takes several buckets.
Clean the rear axle and steering rack bellows by spraying with silicone and rubbing with a rag until the rubber is shiny black.
Clean the brake hoses with silicone until they are shiny black.
Remove transmission and differential fill plugs and verify level and condition of fluids. Consider replacing.
Check guibo coupling for cracking.
Check differential mount and rear subframe for metal tears and popped spot welds.
Order rear shock mount reinforcement kit.
Have a boat cushion to protect seats while kneeling on them.
Have a trim tool for removing blind plugs holding carpet each side of boot.
Order two blind plugs for reattaching carpet on each side boot.
Have a torque wrench and 18mm socket for bottom shock mount bolts.
Support hubs so they don't suddenly drop and hang on brake lines.
Have torque wrench, 18mm socket, and 18mm box end to remove lower strut bolts.
Have a very good spring compressor. Coils seem more compact and stiffer than most.
Grease the threads to reduce friction and binding.
Have an electric impact wrench and 22mm socket for removing top nut.
Check bearing plates, decide whether to order new or re-pack old.
Except for Bilstein, order new rubber bumpers.
Consider new upper and lower spring pads.
Order new lower shock mount bolts.
Consider using a shop to rebuild struts. I got struts apart, but my compressor was inadequate to compress enough to reassemble. The compressor is key.
