hydraulic jacks quest.
My MH has Kwikee hyd. leveling jacks. Recently, one of the rear jacks has begun to slowly extend while driving. When the 'jacks down' alarm sounds, I simply hit the up button, it retracts and then all...

The jack system on my coach (Quadra Big Foot) is power up/down so have I a bit of knowledge on how the system operates. I'm incline to think the retract solenoid is the problem. If the jack internal seals were failing I would expect the problem to also show up when parked and the coach weight on the jack. Same if the extend solenoid was failing, settling with coach weight.
If you want to try swapping a solenoid to confirm before buying one understand that there could be fluid pressure in the valve block even with the system fully retracted and off. Extending the jacks a bit might reduce the pressure but still work slowly when loosing the solenoid to the point of allowing the pressure to bleed off. Have a catch pan close by will help keep the mess off the driveway and have fresh oil to top the system off.
