Rollers were busted and top rack hung low and did not slide out properly

First I twisted out the 2 end caps, you have to kind of slant them to get them to come out. Next, I yanked off the old rollers with plyers. I had a problem that others did not mention in their repair story and is why it took me longer. On the top rack the plastic coating was raised because the metal was rusting underneath, so I had to hammer 2 of the rollers back on the rack, but the other 2 went on smoothly. Last, I slid the rack back onto the guides and put the end caps back in place and it works great again! My husband probably could have done it in 5-10 minutes! I recommend replacing the rollers as soon as you notice one broken, rather than waiting and having the rust issue we had. Much better than buying a new one!
