First ordered and installed new pulley. Greased it. Bad idea. Grease caused new pulley to melt down taking belt with it. Ordered a kit with new pulley, new drum rollers and belt, along with another belt as the one in the kit doesn't fit my dryer. Kit has a belt for the 27 inch dryer and mine is the 29 inch. Cleaned all shafts with alcohol. Installed all new parts and now you can't even hear my dyer running is so quiet. Thanks for giving me genuine Whirlpool parts at such a reasonable price. Replaced everything for 81.10 including shipping.
