Anyone know how to remove these valve solenoids? I saw instructions for a different set online, difference being the other ones had a nut on the top. I tried removing the black plastic cap that's on top but it wouldn't budge and I didn't want to force it.
The reason for removal is my left jacks slowly retract over a few days and before we know it we're all off kilter and I need to re-level by lowering the left side. I don't see any signs of an obvious leak so research has led me to believe it's the Solenoid valve letting fluid pass. I have tried to fully extend than retract to remove any air in the system but it still does it.
