Front Hydraulic jack not holding

[The Landrys]

After leveling my 2018 Montana 3121RL the left front hydraulic jacks does not hold pressure and after a bit that corner begins to dip. Any suggestions as to what I need to do will be most appreciated. Thanks!!

Steve,

Try cycling the jacks including the level up jacks several times. You may have air in the system. Are you seeing a hydraulic leak around that jack?

Hi, my front jack started slowly lowering, it turned out to be an O-ring on the jack that was leaking inside and allowing the pressure to leak off. I took it to a hydraulic repair shop, and they are as good as new now.
