Product review (5 stars): Works perfectly
My 6 year old Whirlpool Duet Sport dryer was making a horrible screeching noise everytime it turned on.  Took a chance and ordered these parts to try and fix it.  Took about 2 hours to take apart the whole thing and replace the belts and all the wheels, put it all back together and it works like a champ! No screeching or anything.  Super happy with it.  I would not recommend this job though to someone that isn't pretty handy with tools and repairs and such.  It was a pretty big job, the entire drum has to come out to replace the belt around it.  As an added benefit I got to clean out my entire dryer, you would be amazed at how much lint is trapped all throughout the interior of those machines.  They have companies that clean out your lint vent, they might want to have someone actually clean out your actual dryer.  A fire could start in there really easily.  Would buy this kit again in a heartbeat.
