Thank you for your question and I understand your concern. Without being there to hear the squeaks/chirps I can't be certain of what's squeaking/chirping but it's likely the idler pulley, however it could be one of the tub support rollers or a slight chance the belt.
In order to access the idler pulley and support rollers the top and front panel will have to taken off. In order to take the top off, the control panel must be taken loose from the top. The left and right hand end cap covers must be taken off in order to access the screws securing the control panel to the top. Once the end cap covers are removed, remove the screw at the bottom of each end cap. See images below.
NOTE: Disconnect the power cord from the power source before servicing your dryer.
If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
