How to replace Dishwasher Lower Rack Roller With Axle. I ordered the wheels and since my billing and mailing addresses did not match because I am in the middle of a move, a nice gal called me. She was adorable and got the ball rolling cleared up the confusion and because she was so nice I ordered the Glisten Cleaner. The parts arrived faster than you can say "fix my problem" . They were easily installed and my dishwasher is "glistening". Than you. Amie Mitchell Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
