Product review (5 stars): Replaced Idler Pulley on my Whirlpool WED6400SW1
Part arrived in OEM Whirlpool packaging. It looked and felt exactly like the old pulley that I replaced. I got everything as shown on the product image.  YouTube instructional videos made installation a breeze. Overall, product looked original and solid. I will write back if anything happens to this part, but hopefully I won't; considering the old part I just replaced lasted 8+ years.
