Leveling Jacks noisy

I have a 2018 Thor Miramar 35.3 and my leveling jacks are ok when I first level the unit but a day or 2 later they start to creek as I walk around inside the unit and it progressively gets worse. Once I pull in the slide outs and relevel itís ok again for a couple of days. Does anyone know what I can do.

I dont have an answer for you but I would have someone wall (jump) around in the RV while I was under it trying to pinpoint the noise. I would also spray anything that looks like it might need lube or make noise with dry lube. Or a maybe wet lube (to get into tight places) then wipe off the excess so it dont attract dust.

Check your hydraulic fluid level & hoses, clean and wipe posts with spray like mentioned above, check mountings for cracks. Reset Zero level, don't rest on the stabilizers with tires off ground. Tires should hold the weight, stabilizers keep it steady.

Since a external leak would be obvious, it's possible to have a internal leak inside the jack or fluid leaking back through extension (bypass) valve(s). With the jacks retracted verify hydraulic fluid level then check the extension (bypass) valves for the CCW position. The link below is the system used on my 2018 ACE but yours may be slightly different. Skip to page 13 for more detail. The LCI website has other versions to chose from besides this basic version. I hope this helps.

This post was in a previous thread concerning popping sounds from the jacks. You may want to check it out.


https://www.lci1.com/assets/content/...CD_0002091.pdf

Called lippert . Need to add a quart of this. Pull in slides and jacks. Then take out a quart of Tran fluid and then add this anti stiction oil.. he stated popping will not harm anything just annoying.Make sure you take out or will overflow.

I don';t know if it makes a difference or not; but the O.P. is talking about a leveling system, and not stabilizers.

By stabilizers I'm referring to the hydrolic stabilizer legs on the Miramar (I own a 2015 34.2 also) that keeps the coach level and stable when walking around inside. When leveling you want to use blocks under the tires to level the coach as close as possible and then use the leveler legs to keep the coach stable. The lifts may also need pads on the ground like the tires... I've seen coaches, tires off the ground. So now the whole weight of the coach plus occupants rests on a couple of 2" posts and not the big beefy tires. Also never never lift the back tires, that's where the brakes are. Automatic levelers as cool and convenient as they are don't realize the tires may not be touching, that's why you need someone out scouting for you.

I have a Miramar was well. They actually have Jacks, not stabilizers. The ideal is for the jacks to carry most of the weight of the coach rather than the suspension carrying the weight. The problem with allowing the suspension to carry the majority of the weight, you will feel motion every time some one walks around in the coach. I have never used leveling blocks to drive onto unless it was so bad I couldn't get level with the jacks alone, without lifting the rear off the ground.

The jacks on your Miramar are designed to LEVEL your rig and carry most of the weight.

Yes, correct, jacks, but the jacks keep the coach stable, so I used that term in reference to the opening question... never the less the info is correct in so far as what the jacks should be doing. Also see below uploaded screen shot from Lippert auto leveling manual.
Best of luck with the new MH.Click image for larger version

If it has all ways drops on the same ram I would suspect the corresponding valves leaking back .
It's an easy part to change. Look on your hydraulic pump while simultaniously checking the manual on instructions to manually retract the legs.
Where in the manual it says use an Allen key to open the valve..... this is the part that needs replacing.
Depending on model may look like this

On our Lippert level system, we experienced a problem that seemed to be a bad pump, it was the directional valve stuck.
Anyway...
Taking it apart to inspect, those hydraulic logic valves are made by Deltrol, and the part number code is stamped on the flats of the hex for removing it."

First remove the nut, oring, and the solenoid, then with a deep well socket you can remove it.
If it is allowing fluid to pass when it should be checked.
We had to find a hydraulics industrial supply to get the part.
It is a $42 part, and minimum order was $80, so I now have a spare.

If you do your own troubleshooting on the hydraulics, be aware there are o-rings at all the hose connections, between the manifolds, and everywhere it needs sealed not to leak.
You don't want to create more problems for yourself!
