Are these Lippert electric jacks?
Take a look at this link and tell me if these are your jacks............http://www.primetimerv.com/download/ComponentManuals/ElectricStabilizerJack-Lippert-OwnersManual.pdf
They have had a lot of issues with this............they get water inside them and it can jam them up. Bad design! IF this were me, I would consider replacing them with another brand. Perhaps even manual jacks as they have a lot less problem and if you operate them with an electric drill, they are just as fast. The other alternative is to have them rebuilt and see how long they last. Keep in mind that these are for stabilizing and NOT for any actual lifting of the trailer. They won't last at all if you do that. Sorry that wasn't the best news, I know...........just one of a few products that should be redesigned. Please get back to me if you need more on this as all follow ups are included in our fee. I am adding a link to the Forest River blog (they use them too) so you can get an idea of what is happening here. http://www.forestriverforums.com/forums/f29/rear-stabilizer-jacks-stopped-working-21203-4.html
