Dryer made screetching, chirping noise then would stop running alltogether.

Turned off breaker, then unplugged it anyway. I need some room to attack this old dog! Pulled out of its hole beside the washer and went to work. Opps, don't forget the flexible vent, I broke it off about a foot from the dryer. Four screws on back, lower right to remove acccess panel. Next two screws under front panel, pull bottom out about a foot and it unclips at top. Read the 5 repair stories about replacing the motor as I took everything apart, all were helpful. Had to put motor in a vise to loosen set screw on pulley, lucky I had a 3/16 allen socket, that was the only hard part, unless you count getting screws out from under the freezer where I kicked them. Be careful. Still ended up with belt in v-groove on back part of drum (where it does NOT go) so had to reach in from front and pull it out about 4 or 5 inches. Things a quiet now and I am a hero around here. Thanks for the good help fellows.
