Lippert hydr jack in front won't stay up

[petef]

I searched, did not get any hits. This is the auto leveling system in a 2014 Hurricane 27K class A. After retracting the RF jack goes back down about 3 inches within 3 mins.. If it sits long enough the LF will go down also, it went down almost to the ground after sitting 6 weeks as did the RF. Rears do not seem affected. I did the phone tech, try this, try that, they advised to replace the valves and coils for the front, that did not work $400 later. Now they say to do a test, disconnect one by one, run the retract and see if fluid spills out from the jack, means bad seal, need new jack. I am not sure I want to do this myself... how hard is it disconnecting the hose ( black hose only) ? Anyone else had this problem?

Thanks

You can just take the hoses loose at the jack. There'll be some fluid dripping so have some rags handy. AND someway to keep dust/dirt out of the fittings.
Don't worry about high pressure or air in the hoses. When your finished cycling the system a few times will bleed the air out.

Here are a couple of YouTube's that might help.
Contact a hydraulic shop to see if they can rebuild your jack

It would be unlikely that you have two bad o ring seals

Use tubing wrenches if you decide to work on the fittings

If the seal is bad it will definitely show up when you crack the return line
