kwikee jack won't hold pressure.

I have a 2006 30B sightseer with level best 3000 manual leveling system,when I level up the left rear will loose pressure and start to rock around sometime it will take 10 min. sometime 20 min. or so. I have bleed the system and checked fluid level no air and full of fluid.Has anyone had this problen and if so what did you do to fix it? Also does anyone know where a check valve is?

My uneducated guess is that the sealing (O ring or such) in the hydraulic cylinder is leaking.
Someone else definitely will know better.

I had a problem with my fright right jack. Everything I could inspect on it indicated every thing was alright. Fortunately I was still under warrant. The coach, (Now affectionately called "Citrus.") was in the shop about 8 times for that same problem. They changed the jack, the changed the solenoid set, and finally Kwikee (HWH) sent them a complete, put together, pump and solenoid set assembled by Kwikee (HWH) It has worked ever since.
