Product review (5 stars): Fits HE2 dryer and repair is relatively easy
Editorial:  Reeeallly disappointed in our Kenmore HE2 washer and dryer.  Noisy, washer bounces around no matter the size of the load, and we've become master appliance repairpeople, especially with the dreaded F21 filter blockage.

OK, enough.  Dryer began making horrendous noises, so we hopped on Google and YouTube and discovered the problem was likely worn out pulley and wheels.  Translated the Kenmore part numbers into these Whirlpool parts, and along with replacing the pulley, spent about 2 hours fixing the dryer.  Works great!
