Product review (5 stars): Replace all 4 rollers at same time!
Arrived promptly, fit properly.  Other reviews indicated that these didn't fit, but I had no problem.  Be careful taking the nylon 'triangle' retainers off the wheel shaft so that you don't break them, as the rollers don't come with any.  Clean the roller shaft really well so that the new wheels don't get junked up again and seize up.  Also consider replacing all 4 rollers at the same time and save the headache of reordering and replacing the others (as I did).  Mine had become junked up with lint, hair, etc. to the point where one completely stopped rotating.  I replaced it and worked fine for 6-9 months until two other rollers began to fail.  Lesson learned...  Also take time to thoroughly clean out the inside of the machine while you have it torn down.  Also check the drum fabric gasket on both ends of the drum- mine was so worn that the drum could move froward/back about 1/2" or more- thus allowing hot air to escape and let more lint, etc. escape down into the bottom of the machine, reducing efficiency and risk of fire due to lint buildup in areas of the machine you can't readily clean.

After all the rollers and the fabric gasket was replaced, the machine runs and sounds like new (very quite...)
