Front Jacks
I had the same issue on our 2013 3400rl. Look at the top of the left jack. on mine there is a solenoid that the lines go into. On the front side of the solenoid is an allen screw, which you probably can't see Try tightening the screw a little. DON'T over tighten it. Just snug it down and that should fix the problem. I think the allen screw is a 5/32".
