The times I've had a stuck jack was because the camper was not going up or down evenly. All four motors seem to run at different speeds I presume due to wire length and I/R loss. The more uneven or tilted the camper becomes, the more tensive rubbing force applied between inner and outer jack tube. Look at the tilt of the camper and try to raise or lower a different jack to level out and relieve rubbing pressure.

If there was a way to take them off the camper, I'd do what I did with an Atwood that got stuck on me.

I took it off and then drilled a hole in the center of the bottom of the foot and flipped the whole thing upside down and filled it with ATF, plugged the hole and then flipped it back up right to sit.

Once I finally got it broken free with the crank handle after much sitting and fiddling, I emptied the atf and put in a liberal amount of diff oil in it and released it and left it in there.

The jack never worked perfectly again, it still had some issues with the drive mechanism if too much load was put on it (if the jack got ahead of the other it would start to slip/bind until the other jack caught up), but it worked well enough to keep using till I got ahold of a replacement unit and now that one is just a parts jack.

Atwoods unfortunately weren't designed to come apart so I couldn't do a proper disassembly and wire wheel cleaning and bearing replacement and then coating all of the threads in moly.

Thanks. That’s not very encouraging that it never worked right again. I’m sorry to hear that.

I will see if they move today after some atf soaking overnight. Otherwise, based on your post, I might be in for 4 new jacks.

ATF worked on one of them!

That’s enough. I have 2 fronts and a back working. Enough to load it up and fix elsewhere after we leave.

Good idea!!! Thank you!
