I can second that. I had my 280ZX on jackstands with wheels hanging for a couple of days and popped the seals on my power steering. Cost me a week off the road and $850 when I got around to dealing with it. On the plus side I got a big improvement in steering. I guess if that's all it took to pop the seals it was near the end of its life. I didn't notice any damage to the suspension, but it was pretty bad at the time anyway so I couldn't say for sure.That could be the meaning. Possible case in point:
I had my 280ZX on jackstands for four years. The front wheels were at full drop.
When I set the car down, I heard a slight noise and then power steering fluid started dribbling out of the rack. I guess the rack seals took a set while the front tires hung down, and when the car came down and the wheels went up to normal position, the seal popped.
