Landing gear, worm gear stripped and dropped 5er (lucky)

I had the same exact problem with my right leg. This is the follower on my 5er. We were out on a two week trip and 1000 miles from home. I was only able to retract the landing gear about half way and was very careful when raising and lowering. Took the leg apart and found the jack screw pretty much stripped and the swedged nut frozen onto the jack screw. Lucky my RV is still under warranty, the factory just sent me a new one. Installed now all is fine.
