jimnina Posted November 18, 2017 Report Share Posted November 18, 2017 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 Link to comment Share on other sites More sharing options...
Devilishjim Posted November 18, 2017 Report Share Posted November 18, 2017 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 Jim Spence 2000 Dodge 3500 1 ton QC 4x4 dually 5.9 diesel LB BD exhaust brake, 6 spd manual trans 34CKTS Cedar Creek 5er, Trail-Air hitch Link to comment Share on other sites More sharing options...
jimnina Posted November 20, 2017 Author Report Share Posted November 20, 2017 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. Link to comment Share on other sites More sharing options...
