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 is well for the next 50 or so miles at which time the when the alarm sounds again. I then again hit the 'up' button and we're good for another 50-75 miles. Before someone says the alarm is coming on because I'm low on fluid...that's not the case. The alarm comes on because a jack has slightly extended. Soooo, any thoughts about what the cause of this problem might be before I take it to repair shop? Any thoughts will be appreciated. / Larry
  • If your jacks have springs, they may be weak.
    The reason Hydraulic jacks extend in transit(if springs are OK) is, the fluid in the jack lines can expand from road/engine/exhaust heat. That can cause a jack to slightly extend. Even with good springs this can happen. Check the HOSE routing for that jack and see if it runs close to a Heat source. Doug

    PS, not positive about Kwikkee jacks. Are they POWER extend and POWER Retract? IF so, then if no leak, you may have a solenoid internal leakage problem. IF Power Down and UP you will have NO springs.

    Kwikee jacks are Power up and power down after looking at the website. So, you have hyd fluid leaking internally at one of that jacks solenoids.
  • I can only think there is a slight leak, or quite possibly air in the system. My right front will do that as well (I have the LCI - no springs), but typically I can get it to hold after I retract it a 2nd time. So far I've ignored it, but yours is going to be hard to ignore.

    I'll be curious to hear what you find out the fix is.
  • my jacks had springs to raise them. evidently yours dont or are weak?
