Question type: Maintenance & Repair

My SLS will not raise up. It is not
leaking it has the oil. What else could
be wrong? Shocks maybe?

And it is real bouncy when I go over
speed bumps

The 560sec has two hydraulic pumps/cylinders in the rear that work on air pressure and hydraulic fluid. Usually the symptom is a stiffening of the suspension as the chambers fill with fluid. In your case, there may be an issue with the hoses applying the needed pressure. These are tricky systems, so whether you use a dealer or an independent, try to find someone who was working on these things when they were new - or you'll be paying them to learn.
