Dewald Leveling Jack Removal

Recommended Posts

We have a 03 freightliner chassis GulfStream YellowStone 39'DP.
I noticed that the passenger rear jack leaks oil really bad while retracting the jacks. I am debating on removing the jack and rebuilding it instead of just replacing it. The question I have is can I remove the one jack without retracting all the jacks? It looks like each jack is independent of each other which makes we think I should be able to just support the RV with a big bottle jack on that location and unbolting it. I'm not sure if it's possible to over extend the jack because I think that is why the jack leaks. I forgot to release the air and then we continued lower the jack until it was in the ground a bit banghead.gif

If you have a separate control valve for each one then yes. If not then you can go to an automotive store and get plugs to fit the hydraulic line that hooks onto that cylinder. while no pressure is on the lines remove and install plugs for that ram and then yoy can jack the other 3 and use bottle jack for the one. And no you cant overextend a hydraulic cylinder

Hey Devilishjim,

Thanks for the reply. I think you confirmed what I'm thinking, so I'm going to try and take a look at it tomorrow after work.
