The above advice is good advice but I have one word for you........
Vroom.
Search Vroom on this site and you will learn what your next move should be.
Your full-wall slide is destine to fail because it is too big and heavy for the lousy Schwintek Slide Mechanism. I estimate 80% of the full-wall slides out there will have one if not multiple issues with the Schwintek Mechanism.
Having to re-level to get it back in is a sign of torquing that the Schwintek mechanism can't deal with because of the slide size and weight.
Every person on this site who replaced their Schwintek Meachanism with the Vroom Slide System has had nothing but positive things to say about it performs. One person just had the Vroom System installed on all three slides on their coach.
I'm not saying you can't get your slide issues fixed / resolved. But I am saying you might spend a couple thousand to have them properly addressed but it will likely happen again. For a little more money you can get a permanent solution that is stress free.
