Hydraulic Experts???
Changed out my hydraulic pump and all went well, it was not lifting the front rams very well. Added fluid and extended front rams then disconnected from truck. Did not cycle anything.
A few days later I retracted the slides and hooked to the truck to head to SoCal. I raised the front rams and then the drivers side ram started drifting down. GRRRRRRR. I then extended and retracted the fronts several times and still it started to drift down.
I had my friend rebuild the rams already with quality parts and I know that is NOT the issue as the RV never drops after disconnecting and leveling.
So I hooked up a strap and headed south. Along the way I noticed the other started doing the same. I drilled they the steel collar and drilled self drilling screws into the silver steel sleeve to hold the rams up when in transit. This had worked for 1.5 months. Been too busy with other things to do anything about it!
My thought is a solenoid is not shutting off when retracted alowing fluid to push past to allow the ram to start dropping.
I have no idea how this system works and what valves do what.
Any help is appreciated. This is on my 2015 39TKSB3 Mobile Suites.

Call Lippert. I think they have two techs that have decades of experience. When I called them, they were very helpful.

I am assuming so also.
Yes I will call Lippert but thought I would see what actual owners had done.

Sounds similar to the problem we had. Rebuilt both sides and the curb side still drifted down. Come to find out one of the hoses had collapsed on the inside and could not tell it just to look at it.
Changed out all hoses and has been working well.

Interesting!!!
I am thinking it's the solenoid that's mounted to the DS ram. Reason the rams now are very slow to retract like fluid is bi-passing.
