Jacks drift down on 2004 Winnebago Sightseer

My jacks drift down while sitting or driving. I can go anywhere from 10 miles to 300 miles, you never know. The jacks drift down slightly and the alarm goes off. I have to pull over and cycle the jacks back up. Any ideas would be appreciated.

I believe that it is all four but not sure. I will check tonight and respond back then. Thanks

I have one hat will drift down on rough roads, just hit the on button and the store button and it goes back up. Just do it on the fly.

Had the opposite problem. When parked for an extended period of time, jacks drifted up. It ended up being bad solenoids. Once I had them replaced so far no issues. However, the big test comes in Dec when we are in Florida for the winter.

Have the seals in the solenoids checked if they are rebuild able. If they are sealed units, then they would need to be replaced.

The jacks up is a single solenoid I believe on most systems. Contact the manufacturer for a spec sheet. If it's POwer gear (LCI) all the shop manuals can be found online.

What type of system do you have? Is it HWH, Lippert, or another brand? If it's HWH don't turn the system off after raising the jacks. Just let it time out and go into the "sleep" mode.

If the system is turned off the solenoids close and won't allow hydraulic oil to return to the reservoir. As the fluid warms from the heat of driving and heat transferred from the nearby engine and exhaust system it expands. If the solenoids are closed the only place it can flow to is the jacks. A jack or jacks only need to move 1/8" to come off the home sensor and activate the alarm.

If the system is allowed to go into the sleep mode the solenoids stay open and the fluid can flow back to the reservoir. If the jacks still go down when the system is in the sleep mode check for a hydraulic line running close to a heat source like the exhaust system, and reposition it if at all possible, or add some insulation around it if moving isn't possible.

Also if the system is left in the sleep mode you can push the "Store" button and the jacks will return to the home position.

Drifting JAcks

Thank you everyone for your suggestions. To start with my system is a KwiKee Level Best. I do not have a "store" mode that I can find. The directions say to retract the jacks using the "ALL UP" button. When retracted the light goes out and the pump stops. It says to then turn off the power switch and the vehicle is ready to travel.

Am I missing something?

Thank you all for your input.

Jacks drift down on 2004 Winnebago Sightseer

Same thing happened to my 2007 Sightseer. First thing I did was to make sure the hydraulic fluid was at the proper level. Do this when the jacks are retracted or you'll overflow the fluid when you retract them. It still gave a "false jacks down" warning, but I just turned the system on while driving and hit the all up button. Had to repeat the process a couple of times, but it is no longer giving a false warning. I think the jacks just had to be cycled through a few times in order for the new fluid to circulate totally.

You may already have these two attached items but if not you may want to download them. The emergency retraction harness did not come with my 2004 Sightseer and I bought it from Winnebago through Lichtsinn Motors a dealer close to the factory.

This is a very good point- it is also possible that you have air in the lines. Since pressure also keeps the jacks up, perhaps you need to bleed the lines, or cycle the jacks several times?

On my 2004 Winnebago (hwh system) I frequently would get a jack down alarm when driving. That is normal as temperature changes apply pressure to the Jacks. When that happens just press store and the light and alarm goes off in a short amount of time. Some time when departing I just press the store button before I leave and leave it on and the alarm either never comes on or if it does goes off in just a few seconds. This is explained and covered in either the hwh manual or the Winnebago manual, can't remember which one.

Clay,
Thanks for the information. I looked at the first link but my unit is not the same. No auto mode and no individual control to each jack, only front two, back two, left two, right two. Anyway I will look at Kwikee website and see if I can find mine. By the way, it is only the front passenger side jack that is drifting. Thanks again.

I found out that it is only the right front jack that is drifting so I assume it is a solenoid. Thanks.
