When tub was turning it had a grinding sound.

First unplug the dryer from power. Now open the dryer door and remove the two phillips head screws that hold the top down. Then lift the top off and turn the dryer on it's back (this is not necessary but if you have the room it makes the job easier). Now remove the two hex head screws that hold the front on and remove the wires from the door switch. Now you can lift the front of the dryer off, door and all. This now allows you to replace the three (on this model) slide bearings and the felt. I also removed the belt and lifted the drum out and checked both the belt and the rear bearing. You can do it!
