HWH Hydraulic Leveling system problem

Today I noticed the passenger rear hydraulic leg is not extending as fast as the driver side leg. I tried cycling it a few times, didn't help.

Air in the line?
  • Problem solved. The fluid was very low and I discovered that if I pull the joystick forward or backward the corresponding legs will extend but then if I pull the joystick to the left or right while holding it forward or backward the legs will extend at different speeds.

    The joystick only moves about 1/8" left or right while pulled backward or forward but that is enough to alter the extension speed. Never realized that till today.
  • Have you cleaned the control rods, if equipped? What model of levelers? Are they kick down or straight acting?
  • Possibly air or low hydraulic oil in the system. With the jacks fully retracted, top off the fluid and cycle the jacks several times. That will remove air from the system. Then check the fluid level again.
