Whirlpool Gas Dryer Has the Squeaks

I had a Whirlpool for several years. About once a year the drum support wheels would go bad and squeek like crazy. I finally modified the brackets to hold wheels for inline skates. (Ones with real bearings instead of some nylon material turning on a metal shaft.) No more squeeks and the dryer sold with the house when I moved 5 years ago. The couple who bought the house was a bit concerned about the age of the washer and dryer when they bought it but when we saw them a couple of months ago they commented on what a good washer and dryer they turned out to be.
