How to take dryer apart to get to back
 

I'm having a harder time than expected taking the back panel off b/c it is one big piece that wraps around the sides of the dryer. I'd like to take it apart so I can see the belt and other parts in the back b/c this morning the dryer started making a somewhat high pitched whining sound while a load was going. It still tumbles and heats up I think, but I'm concerned about the noise. I already cleaned out the lint trap and vent. I'm just wondering how to get to the right screws that will release the panel.

You have to remove the front panel in order to access all parts.

Here are the breakdown diagrams and Replacement parts for ADMIRAL LNC7764A71 | AppliancePartsPros.com, the model is very similar to yours.
