Heck, chances are good that leaking SLS valves are in large part CAUSED by weak springs.
Sorry about the shouting, its just that everyone seems to ignore this.

I'm not convinced that this is true, so it's not just a question of ignoring it. There has to be some pressure in the SLS system at all times in order for the accumulators to function. On a brand new car, would the rear end sag if the hydraulic cylinders were removed?
Can anyone direct us to a part of the FSM where this is explained?
