No squeaking, and Yes on Tioga. Just scraping and horrible sound. And it will tear up the flooring if you try to put slide in or out without positioning roller. Roller is attached to floor and supports kitchen counter, oven, and cabinets--in fact entire kitchen except for refrigerator. It is also a very big,very heavy slide. (Roller was sideway, as shown in first photo, with sharp screws poking up, so I had to push it so the roller was rolling the right way.) I was able to get it closed and left it that way until I could find someone who could repair it. And of course, no one had any parts!!! Roller was horribly bent and it was week before Christmas, 2017, plus only slide guy was going on vacation and I was headed to visit relatives.
I will have to say Bakersfield CA Camping World did an excellent job of bending bent roller back into shape and screwing it back into position as a temporary fix--but at a large fee. (Takes a long time and at least two service people to move slide out and access rollers, etc. so it was expected to be expensive.) Ordered new roller from Fleetwood, which was sent to me, and took RV to REV repair in Eugene, where it was fixed, at another large fee. However, roller came loose again at 89 days into 90 day warranty on the April repair. Junky pseudo-plywood does not do a good job of holding it, so back to REV again and re-repaired at their cost. But this time, they screwed it straight through slide and through steel plates on top and bottom. That was July. It had BETTER NOT come loose again!! Second photo shows the plate on underside of slide.
By the way, I strongly encourage anyone who knows they need a part replaced have the part shipped to them and not a dealer. That way, you know it is the right part, and that it is actually, really and truly available.
In fact, if you suspect a slide roller is loose, you need to get help putting the slide in and have someone use a piece of wood of something to slightly lift the slide and watch the roller so the screws in it do not tear up anything--like flooring or cabinets. I had my son help me. He thought I was nuts until he saw the sharp screws and the damage they could do. He ended up reaching in and removing the screws. In fact, I don't think you should EVER force a slide in or out unless you know what is really going on. That includes manually putting a slide in if there is resistance or weird sounds, etc. Also, if you have a kitchen on your slide and the roller is no longer supporting it, use something to temporaily support it--like stack of books or magazines on the corner. Don't want cabinets to droop and pull away from wall.
I am getting to be an expert at slides!!
