It does not look like the self leveling is working properly. I raise the back of the car and put it on jackstands and "manipulated" the valve lever arm and did not see any movement of the back tires - elevation wise. This was done with the car running at idle. I'm sure my pump is working because of how fast it pulled the level down when I changed the fluid yesterday. Any thoughts on how to verify that it is the valve versus the hydraulic shocks? Should the movement of the rear tires (up/down) be instantaneous when I manipulate the valve lever? Worst case I will just replace the valves and shocks. Oh yea - at the back upper part of the wheel well the height from the ground is 23.75" running 205 70 14 tires.
