Lippert hydraulic landing gear

I have a 2014 Silverback 29ik. We have the lippert hydraulic landing gear /jacks. They both seem to work fine operate in both directions ok. No fluid leaks. Simple retract and extend switch, no blown fuses.

My issue is as follows:

Park 5er on relatively flat brick paver or concrete pad. Extend landing gear, unhitch tow vehicle. The passenger side hydraulic jack seems to extend slightly more then the drivers side hydraulic jack. Causing a slight left to right leveling issue. I can't for life of me get trailer level side to side.

Both jacks run off same hydraulic pump/fluid system as do the three slides. By visual inspection I'm not leaking fluids, fluid levels seem ok in reservoir which tells me seals in jacks/Rams ok.

By visual inspection frame is straight and true all welds in tact. Haven't even bumbled a curb in this trailer.

My question is there a way or procedure to adjust the two hydraulic landing gear jacks? I see nothing in the trailers documentation from forest river or lippert.

I'm relatively certain it's a hydraulic jack pressure issue between the two landing gear but strangely I'm just not seeing the obvious symptoms of why its occurring.

I'd prefer not to haul a bunch of wood blocks to drive the trailers low side wheels up on to in order to correct this if in fact there is something I can do to address this at the landing gear.

Thanks in advance for help or ideas.

    This little tidbit might actually be relevant to the OP's question: "Why are my hydraulic legs lifting more on one side than the other?"

    Mine usually go down, one first then the other, then when both getting resistance, they both rise together. If the OP's are not doing this...

    Maybe a bad valve?
  • As eHoefler said...you have to level the rig side to side by blocking the wheels with blocks or boards...the front jacks are not levelers except fron to rear. When you lower the jacks, the hydraulic pressure equalizes then raises side to side equally.
  • The only thing I can think of is if one side of the front of the trailer is loaded a lot heavier than the other. This might cause this.
  • The jacks don't level the coach side to side, they work in tandem. They only will level front to rear. They have an equalizing valve once both legs meet the same resistance and raise the coach. You must level the coach side to side by using blocks under the tires. The front jacks/landing gear will not operate independently.
  • There is no auto. This is simply two hydraulic landing gear jacks operated via a simple "Retract/Extend" toggle switch.
