No problem. The rollers to look at are adjacent to the slide mechanism, front and rear. On my unit, these rollers are easily adjustable. If you don't want to do it yourself, which I understand, you could inspect them, and if they're not contacting the floor plate, at least you would know you have a potential problem and could have it addressed before a failure occurs. On my unit, I can see the wear pattern on the floor plate so I know the rollers are in contact. When I received the unit however, the rear roller was not touching the plate and I adjusted it accordingly.
