dryer was noisy - low growling

Removed top cover by removing 2 screws in front door opening. Then removed front door removing 2 screws, one on each inner side of the front door.
Removed 2 screws on side doors located about 9 inches from bottom of dryer to permit taking off drum. Slip off belt and remove drum.
Thinking I had a bad bearing, I decided to turn the dryer on and found out I had a bad motor-still functional but noisy. I had difficulty installing the new belt since there was not access panel (which was mentioned in the service manual), so I decided to take off the left side panel-about 8 screws. With the left side panel off, it was a lot easier to install a new belt and install the new front bearings. I actually did not fix the noise, since I need to replace the motor ($$$). When it goes really bad, I can order it then, and it should not take me long to replace it.
