To remove the from cover there are screws at the top front corners as viewed from the inside. (you have to have the top tilted up to see them)
There is a module inside of the front panel that has 3 wires connected to it. Remove these, (make sure the dryer is UNPLUGGED first) The whole front should lift off now. Next remove the tumbler drive band, and lift out the tumbler. Now you should be able to see the wheels that the tumbler rides on mounted on the back wall. One or both of these is probably making the squeeking noise. They are held on with a snap ring that can be removed by placing a screwdiver in one of the visible slots and turning. There are nylon gromits behind the wheel that may need replacing. Also a little bit of wheel bearing grease will help.
