ATF soaking it overnight has freed things up for me in the past. Marvell Mystery Oil and PB Blaster have also worked after soaking in. Are they over run and jammed or just corroded in place? If corroded, a couple of whacks with wood block from the top and bottom may free the threads.
They are corroded and stuck into place in the middle of the stroke.
The camper is sitting on the jacks right now and has been for 8 months. They were a little sticky before, but are stuck hard now.
I’ll try some overnight soaks and some whacks.
