Is the slide out mechanism made by Lippert / schwintek? You can tell. If it has two rails on either side of the slideout it is a lippert. I have heard of those mechanisms geting out of synch. They use two motors, one on each side of each individual slideout and they have to move in perfect synch, or the slideout will jam or bind up in the opening. There is a procedure that i heard on how to get the motors back in synch, but i dont remember where i read it. You can probably google it. If it isnt a lippert and it is hybraulic, check for leaks in the hydraulic lines leading from the pump to the hydraulic rams, only other kind of system i know of is a sort of rack and pinion system. My slideout system is made by power gear (lippert also owns that brand now) and it is a single motor connected to a shaft that runs 2 gears on two tracks under the slideout. But i havent heard of those going out of whack because its only one motor. UNLESS for some reason a gear jumped a tooth on one of the tracks. Anyways good luck
