It’s a 2013 Winnebago Journey 34b, and the slideout system is Lippert.
Do you have the factory manuals that came with the MH? They include a part on the slide systems, specifying exactly which system you have in your unit. I think it is the Supplemental Manuals book - pretty extensive, listing every system on your MH. Once you get the make and model of the slide system, you can look on-line for the support manual, listing the adjustment procedure.
Phil-t is on the right track, I know on my (2013 Winnebago Vista 30t ) every once and awhile I have to sync the motors on each side of the slid (mine is also Lippert 2 tracks per side, motor with gear is located at the top and a shaft runs to the bottom gear). That procedure is to run the slide all the way out then run it in 5 or 6 inches then run it back out (holding button down till the slide stops) then repeat a couple of times then attempt to close the slide. But again I would check my owners manual for your type of slide.
