LCI leveling jacks retracting too fast

I have LCI hydraulic leveling jacks under my 2006 Airstream A37, the problem is that the jacks retract very fast, it literally drops the coach!!!, (very scary sight/experience ) is there a way to control the return flow of the hydraulics or adjust the retract speed in anyway?

Thanks in advance

If you dump your air tanks to level try letting them air up to about 60 or so pounds. I think you are feeling the sudden drop of the motor home as the jacks retract. I started doing this & the jacks retract nice & smooth.

yes, add your air first and then the jacks
should not be as troubling, shaking, or
'fast' - should be much smoother

That's the way I do it, I fill up the bags completely, but still the drop is very fast and violent. I was wondering if there was a way to restrict the oil flow going back.

go into manual mode and control the jacks that way... may not be the best solution, but at least it will give you some control.

I don't know your hyd system so this may not work. If you install a hyd oil flow limiter(one way) the rate of descent may be dialed in to your preference. We used them on our old Farmall tractors front-end loader to control rate of fall.(the system was hyd pressure to lift, gravity to lower) a bucket full of dirt fell VERY fast.
When the bucket was lifted there was full pressure and volume flow, only the return flow was reduced.

That said, I would contact LCI first, there may be something out of adjustment.

What they said, it sounds like on your system, the pressure is dumped before the pads are brought up vs using hydraulic pressure to raise the pads, which would result in a smoother release.
