leveling jacks issue

Hello fellow Georgetownians, we have been full timing in our 2012 378 and I keep hearing little creaks under our unit in the area of the jacks and it feels and appears that the leveling jacks are very slowly and incrementaly retracting. Anyone else have this problem?

My driver's side rear jack always seems to move. I've been under the coach looking for a source of a leak but didn't see one until about a month ago. It appears that the hose coming from the other rear jack has a small amount of fluid on the hose that runs over to the driver's side rear jack. I was able to tighten the hose about a quarter turn and then wiped everything down. I then ran the jacks up & down a few times and I don't see any fluid, but after a day or so it looks like the same jack retracts slightly. I'm not sure if temperature has a bearing on this or not. I would think if it did then all of the jacks would be effected at one time or another but it's always the same jack. The jack doesn't move much so I don't think the valve at the pump is allowing fluid to go back into the reservoir. Once the weather gets warmer I plan to venture back under and look around some more. I also plan to measure from the ground to a line on the side once I first level the coach and see how far it retracts and how long it takes before it stops moving.

Look for any small set screws on the jack housing. They are used to bleed the jacks of air. I found one of mine was loose causing a small leak. Tightened it down with an Allen wrench. Took care of the problem. Hopefully your problem is as small as mine was. Good luck.

Are you currently on a gravel or concrete pad? If it's a gravel pad it could be that setteling is taking place. I have a 2012 378TS and every time we stay on a gravel pad site for a few days a poping or sometimes a grinding noise is a result of the rocks being crushed or just moving due to weather changes and walking around inside. This will occur continuously for the duration of the stay. Anyway, just a thought.

Charlie, thanks for the reply. Funny that you mentioned temp. as I noticed that it appears to be worse when the temp is changing. Lately here in eastern SC the temps at night are in the 30's but during the day is rises to the 50-60's and the noises occur during the time when the temp changes a lot. The bedroom door is a little hard to open and swings by itself so I know the rig is moving. Don't see any leaks though.

Craig, thanks for the tip, I am going to climb under and see if I see any leakage on top of the units. Never thought about bleeders on the jacks, I know there is one on the pump. Went to a KOA in Charlotte and got a site with an incline. The automatic jacks leveled the unit but the rear jacks were extended far enough to have used all of the tranny fluid in the tank and sucked some air into the lines. Could not retract the jacks or the slides until I refilled the tank, ran the pump, bled the motor/tank and then waited for the air in the lines to run it's course. Then I made sure to leave the cover off the tank as it overflowed when I retracted the jacks and slides. unit needs a larger capacity tank

Ray, we have noticed the same thing, particularly in the front. I have looked for leaks and have found none. I will look for the air removal screws, but would have thought I would see fluid if they were leaking. This also occurs on none gravel, solid concrete. To me, it acts like they are "settling". Keep us up to date if you find something. I will do the same.

anwall, thanks for confirming that I am not crazy! Like you, ours is in the front as well. And like you I do not see any evidence of leaking fluid. "Settling" is a good way to describe it. Please update us if you find out anything and I will do the same......

Ray, I think the next time I put it up on the levelers, I will make some measurements on the legs. Before I put them up, will re-measure. If there is movement, I have until the end of June to get it back in for some Warranty repair. That is if Lippert has a repair!! I have not read to much on the forums that give me that warm and fuzzy about Lippert levelers.

We are full timing in our378 and have had the same issues with our front jacks, mostly the front left, on gravel or concrete. Looks like we are all in this together.

Sent an email to Lippert Customer Service asking a few questions about the levelers. I'll post the response once I get it.
