Manual Adjustment to one Hydraulic Level Up Jack

Have any of the Trilogy Owners had any experience in manually adjusting just one hydraulic jack? As you can see in my picture, my front roadside jack is over two inches lower than curbside and cannot be corrected via the electronic system. Also attached is the diagram from Lippert’s site. Any guidance on the following would be helpful:
1. On my 2013 Trilogy 3650 RL, which landing gear diagram is for my system?
2. What type of equipment do I use on the port to extend my front roadside jack? Is this a pressure fitting if so, how much air pressure and type of fitting? If not, what type of equipment will I need?

My rig is at a seasonal site and need to be prepared when I get there.

We had a similar problem only ours got stuck in an elevated position (think high enough for a stepladder). We recently had the motor go out on the bedroom slide so we had a mobile mechanic at our site (we're also seasonals). Since he was there we asked him if he could help with our Level Ups before we got nosebleeds from the elevation. He messed with it a bit and scratched his head. After giving it some thought,hubby suggested he shut down the entire system (hard reboot if you will), wait a few minutes and then try again. Pushed the automatic level button and it worked like a charm. Not sure if we were just lucky or if that's what we were supposed to do.

I looked at the attachment. If I were you, I would print a copy and take it to the camper. Look at each leg in the diagram and see if it matches the one on the camper. For instance, the "Steel Leveling Jack" shows 7 holes on each side of the jack in the diagram. Do your front jacks look like the one in the diagram? The aluminum one shows 14 holes on each side of the jack. Does it match? Same with the hydraulic plumbing. Just look and compare to what is installed and narrow it down.

Alternatively, look for a data plate on the jacks and get the part number and serial number. Then contact Lippert. I believe someone said John Armstrong is now working at Lippert. He would be the goto guy for information. Sorry, don't have his email.

We can stick a fork in this post. This odd issue is something that the shop needs to see and/or fix. Might be a pressure issue, but either way, there is no acccess in the jack that will allow a manual adjustment, to just one front jack.

Lippert and Matt at Trilogy have been great to work with and completely answered all my dumb questions.

Is your trailer actually level? If the black painted part of your jacks is the same for both landing gear, the issue is with the rear jacks. The fluid will freely shift between the two front jacks as the left and right rear jacks operate. My trailer was delivered out of level -- nose down, left side down. I rezeroed the system and am happy with it.

Thanks again for the feedback. Bear with me on some clarification on Level Zero Point Calibration. I have pulled up the directions for this and from what I have read, you are pressing the front and rear buttons 10 times clearing out the former settings, then manually level with a carpenters level. If I am correct so far, not sure this will help. My problem is that the front roadside jack, is 2 inches lower than the curbside front. It is my understanding that the front landing gear are plumbed together and there is no way for me to correct the difference in the front manually, once the system is returned to Zero. Donít get me wrong, I am willing to try anythingÖ

When I level ours, the front left leg goes down until it senses firm resistance, then the front right leg goes down until it senses resistance. Then when it does the autolevel thing I can see that the front left and right adjust independently.
If they were plumbed together and there was more weight on one side than the other it would slowly creep out of level. Also (I haven't had to do it yet) some folks say they can lift up one side and change a tire.
I hope I'm not totally wrong with my theory.

I am totally baffled reg. the difference in height between the 2 front legs, that should definitely be corrected. I would say that either your selling dealer or Dynamax C/S should be able to fix it or at least walk you through the process. Changing the bolts is piece of cake but how it affects the auto level I don't know, but I would suspect that it has nothing to do with the position of the mounting plates.
If nobody was looking I would probably just mess around with it with the battery disconnect in one hand - just in case (you did not hear this from me).

I have seen the same, independent movement, late in the auto level cycle. In fact it is the low side dropping down, independent of the curbside. That being said, I donít see a way to correct the low side manually. The manual function for the front is plumbed together.
