Saturday morning.  Time to put some finishing touches on the monster cabinet in my garage. 

Wait whats that - the dryer is really squealing.  bad.  Ok, after we work on this cabinet I will take a look. 

It's probably just the idler or a roller.  Pull the dryer apart.  It's not a $15.00 wheel.  It's the $150.00 Motor. 

And its Saturday and it's 4:00.  No appliance stores open anymore. 
11:00 Sunday morning I am at the appliance parts place here in West Bend.  The motor is discontinued.  But they have one in stock!  So by 12:30 we are back up and drying clothes!
