Well, my friend you have a classic SLXXX problem. After so many years the seals in the 11 plus hydraulic cylinders
Become brittle and crack. I bought a 97 SL500 that leaked oil on the ground from those tubes that stick out
From the bottom of the car. I removed them and sent them to Top Hydraulics in Oregon. They overhauled them and
Sent them back in a couple of days. It was a lot of work but well worth the savings of going to a dealer.
Check the oil level of the pump. It is located underneath the spare tire. Do not run the pump dry or you could damage
It. $$$$$$ !
Hope this helps
