Product review (5 stars): My 7 year old Whirlpool Cabrio drier had an annoying squeal from the pulley
My 7 year old Whirlpool Cabrio drier had an annoying squeal from the pulley.  This kit was easy to install.  It took about 1 hour and that included vacuuming the machine really well to remove all the years of lint build up.  I also blew high pressure air around the whole underside of the machine to remove any lint the vacuum could not reach.  While you have the machine apart take the time to clean up the underside parts.  There was lint everywhere on mine.  It could be a potential fire hazard.
