bumping thread as I want to take a look at this once the car is running again.

So it seems like my non-functional SLS is either pump or valve...but a reminder, car ride is perfect in the rear, even with weight so I think the sphere's are functioning fine.

So if I peer into the reservoir I should be able to see if the pump is circulating fluid right?
If it is circulating fluid, it should be safe to say that its probably the valve?

I have not checked what setting the valve lever is on, but as babymog said, 3 settings...but to clarify, do any of those 3 settings DISABLE the SLS? Where "should" it be set at?

If its the valve, can they be taken apart and rebuilt or is it a replacement only? Looks like they are ~$380.
