I just had some questions about replacing the rear shocks for 94/S500; how did you get to the top of the shocks? And what kind of oil should I use when the job is done? It looks like I have a leak somewhere, so I'm planning on adding some oil first (BTW, should the car be on when I add the oil?) to see where the leak is coming from. I hope I don't have to change the pump. If you have any ideas to help me with this issue, I would really appreciate it.
