Big slide rubbing on floor.

I've been under moho so have 2 rv mechanics. Can't find anytype of adjustment. Is there some type of service panel to remove? Neither of the guys had worked on a 99 Pace Arrow.

The Galley slide on our National Tropical came with four rollers under the slide. After nine years, two were broken at one end. We had them replaced in Elkhart, IN and the shop added three more rollers.

I think most flush floor slides sag in the middle when they are all the way in. Mine has since it was new, but it stays above the floor until the last few inches of movement and does not scratch the floor or leave any marks to speak of. If it's rubbing marks on your floor your slide may need to be adjusted, but there are some plastic strips that go between the floor and the bottom of the slide that are suppose to stop the marking. Check with camping world or other rv supply stores.

Likely sagging from wood rot. If it is wood framed ince wood takes a set your done. You need to make a careful inspection, determining of it is wood or metal, then devise a plan of attack.
