"Creaking and noisy' Levelers

Call Lippert , they are aware of the issues . I have drained and changed my fluid to synthetic which did help the noise issue . The biggest improvement was to make blocks of wood 12in by 12in and stack under all the legs so they do not extend more than 3 or 4 inches .For extended stays I still have to relevel the coach every two weeks to stop the ticking sound at night .I have returned to the Winnebago factory twice there are no leaks . I have learned to live with it .

I should clarify the 'jacks down' error was when it was parked in my yard with the jacks up....

What you need to do is add ANTI-STICKSION oil additive to the reservoir. This fixes this error on both PG and Lippert HYD jack systems that have very small creaking and groaning problems. Doug

Doug is probably one of the most knowledgeable people in the US and we are fortunate to have him post on this forum. Thanks Doug for your sharing your knowledge with everyone.

How can it be the jack system when he says the jacks were up?

I have seen that issue on occasion. Jacks retracted when it's cool outside then get jacks down warning when it gets warmer. Expansion of hydraulic fluid as it warms up. Pushes the jacks down far enough to trigger warning. Quick touch of retract button solves it.

Sorry, did not see the problem with the jacks down and he retracted and it fixed it. LCI jacks use a Pressure switch on the Manifold that sends the signal when jacks are retracted. LCI jacks do NOT have sensors for the jacks down or retracted in the usual sense. They use a pressure switch on the manifold that since LCI jacks are power up and down, when retracted there is a static pressure. When the jacks all fully retract, the pump then pumps the pressure and shuts off. THAT pressure is what the manifold pressure switch reacts too. IF you have a small internal leak in the system, the pressure drops a little and the Jack down error is called for. You then do a ALL retract and the pump pressurizes the system again to satisfy the switch. MOST times the pressure switch is defective and you replace it. Doug

This is the pressure switch.

I was posting about 2 different problems, noise with jacks down and 'jack down' error with jacks up. Sorry for the confusion. Going to buy some 'Cat oil'.........

I had noises and resetting issues, quick fix was Gordys, keep the levelers from extending to far. Proper fix is to replace hydraulic fluid and springs when you can.

Really? WHY change the Fluid? FYI, this LCI system does NOT have springs. Doug
