Frigidaire Dryer, Model #: GLER341AS2, How do you get the back off?

You don't. Everything comes out through the front. Use a putty knife between the top and front panel to release the two clips that hold the top down and lift it up and tilt it back. From the inside remove the two screws (one on each side) that hold the front panel on. If you have to get to the heating element, it is behind the drum. Two release the drum from the rear bearing you have to lift sharply at the rear of the drum then pull it out through the front of the dryer.

Is there a trick to the dryer belt and putting the drum back in? After I replaced the heater element, my dryer no longer tumbles and the belt is more loose.
