Adjusting Slideout

I will make small adjustments and run the slide in and out and hopefully will have some improvement. There have been grease marks on the carpeting after the slide has gone out and both end caps inside (the fake wood vertical stiles) have popped off as well and I've had to reattach them. Where it sits on the floor now sits up higher than before. It used to sit about an inch up from the main floor when the slide was in. Now it sits more than two inches above the main floor and no, we've never stepped on it while in. The squeal really is bad. Not the kind of little squeal that's annoying and temporarily better because of using lubrication. I've done all that more than once with no improvement. It's the kind of squeal where people at a campground, hear it and look over. Some have even come over to tell me "That's not right". It wasn't until I took the seals off that I noticed how out of square the slide is. I'll accept that it may not be square or be perfect after adjusting it but hopefully there will be some improvement.
