FWIW, adjusting slide mechanisms is not for a novice. Even many RV dealers service depts. do not know how to properly and accurately adjust the mechanism. The service literature Jim linked to is perhaps the best advice for us novices at adjusting a slide mechanism.
When our 5er was new one slide did not fit right. The dealer service dept. adjusted the mechanism, but it still cut the carpet, so I bought a set of "slide slickers" . Well, that mechanism finally failed. We took our 5er to the factory for a list of needed repairs. When they inspected the slide mechanism they said it had been mis-adjusted for a long time, and finally the gearbox broke, gear rack stripped, and one main slide rail was bent. I have no other answer than the selling dealer service dept. was responsible.
Best part, the factory service manager did not charge us for repairing the slide mechanism because we had $2,000 of other work performed.
