We’ve had a handful of members write in wondering what to do when the leveling jacks on their RV’s slide room, fifth wheel or tow trailer aren’t working properly. For most of these cases, their hydraulic system has either taken on a disturbing growling noise upon descension of the leveling jacks or they simply won’t retract back into the rig. In this free lesson, RV expert Dave Solberg walks you through a quick explanation to explain how you should troubleshoot when you discover RV leveling jacks not working properly on your rig.

With Dave’s help, you’ll learn what to look for when you notice there’s an issue with your leveling jacks. He shows you how to diagnose the problem, then introduces a few tips for finding a solution. Growing typically means there’s corrosion somewhere in your hydraulic system, and each manufacturer has its own recommendations for troubleshooting. However, Dave believes just about all will steer you away from using any chemicals other than WD-40. Find out what else you need to know to troubleshoot your fault leveling jacks!

    Dave,
    My Fleetwood Southwind has grease fittings at the bottom of the cylinder. I just pumped some grease into to them. Will that hurt anything? What kind of fluid should I use in the system reservoir?

      Hello Joe,

      Typically Fleetwood used the Power Gear leveling system which is now owned by Lippert Components Inc (LCI). According to the Power Gear manual, they recommend the following:

      Type A automatic transmission fluid (ATF, Dexron III, etc.,)will work satisfactorily.

      Mercon V is also recommended as an alternative fluid for Power Gear leveling systems operating in environments with large temperature swings

      Operating in cold temperatures (less than -10°F) may cause the jacks may extend and retract slowly. For cold weather operation, fluid specially-formulated for low temperatures may be desirable:

      Mobil DTE 11M, Texaco Rando HDZ-15HVI, Kendall Hyden Glacial Blu, or any Mil. Spec. H5606 hydraulic fluids are recommended for cold weather operation.

      The grease fittings are generally designed to add a small amount of grease to disperse moisture in the cylinder so it should be good.

      Thanks,

    One Jack refuses to retract. I have used some spray on it – that worked previously but now it doesn’t.
    Previously somebody said a fuse blew…replaced it and it worked. 2000 Itasca Horizon Class A.
    What suggestions do you have for resolution of the problem

    I have a 2012 Tiffin Allegro Open Road. My left rear leveling cylinder will not stay down. I replaced the solenoid valve, and it worked for a couple of days and the started creeping back up. Can anyone give me some ideas of what to look for or at?

      Hello,

      There are a few possible causes. Check the solenoid valve for any leaks. The cylinder itself could have a an internal leak, would have to check the seals. The manifold has a check valve that could have failed. Debris could have also entered the system either when the solenoid was installed or prior. You would then have to clean and flush the system. Make sure to visually check everywhere for any sign of a leak.

      I hope this information was helpful.

      Hello Tracy,

      You will need to take the unit back to the service center that replaced the air bags as there is something wired wrong now that shuts the system down. It’s not something that can be easily diagnosed without knowing exactly what was replaced and tracing the wiring system.

      Thanks,

      Hello Walter,

      It depends on what kind of system you have, electric or hydraulic and also what the control system is called manufacture/model. A lot of times if you ran them up with the emergency switch the system would need reset. You can usually do this by unplugging the wiring harness to the controller and leave it out for a few minutes. Re install it and then test the system. If the jacks or slides are in a different position it will cause an error and things won’t work. You can also disconnect all power from the coach to do the same thing. Sometimes this will help in this type of situation. If it doesn’t help, I would need to know more about the system you have, manufacture and model of the lift system and control board would be a big help.

      Thanks,

    I am looking at an Itasca sunrise (2002) with a possible fire in the very front of the RV. I think this is a pump for the leveling jacks. I need more info.

      Hello Lee,

      If the coach has a hydraulic leveling system, the pump and reservoir is usually located near the front. I’m not sure what information you need, is there a problem with the system? Are you saying there was a fire in the front of the RV that may have damaged the system? If you could elaborate on what information is needed I would be glad to assist you the best I can.

      Sincerely,
