Product review (5 stars): Installed and 30+ loads later....Working great!
Nerve racking noise has returned to a lovely hum once again.  Replacing the parts wasn't complicated.  Getting the putty knife in place to pop the front tabs was interesting.  Be gentle removing the old plastic wheel locks/tabs.  If you break one during the install of the new ones, the old ones will be there to save the day.  If you understand or know how to finess them off without breaking them, you should be good getting the new ones on. Take your time and.....get'er done!  The money saved, and the peaceful drying of clothes (once again) is well worth the effort.
