Power Gear leveling Jack settles after time
I have power gear hydraulic leveler and my passenger side rear jack will retract slightly after a day or so. I've had this jack seals replaced a couple of years ago due to a leak. There are no signs of leaking this time. I'm wondering if there is something else that may possibly cause this. Perhaps a bad check valve or leaking o ring somewhere. Anyone else have this problem and know where to start checking? It started doing this about 4 months ago and definitely not leaking anywhere. It will settle a little after 1 day.
