It is proably the center bearing in the back of the drum, especially if it at least a few years old. It can be replaced by you if you are very handy.

YOU MOST LIKELY HAVE A REAR DRUM BEARING FAILING. IT IS A SMALL TEFLON BEARING THAT SLIPS ON OVER THE REAR SHAFT OF THE DRUM AND INTO THE HOLE IN THE REAR OF THE DRYER. THERE ARE ALSO FRONT GLIDES THAT SUPPORT THE FRONT OF THE DRYER. OLDER DRYERS HAVE THE FRONT SUPPORTS UNDER THE DRUM SO THE DRUM RESTS ON THEM. NEWER G.E. DRYERS HAVE A PLASTIC RING WITH THREE TEFLON GLIDES ON TOP OF THEM AND THE DRUM HANGS FROM THESE GLIDES. REPLACE ALL OR SOME OF THE ABOVE PARTS TO ELIMINATE YOUR SQUEAK.
ON OTHER POSSIBILITY, THE IDLER PULLEY THAT KEEPS TENSION ON THE BELT CAN BECOME A SQUEAK MAKER.

If the squeaking has been going on for only a short time, you may be able to get by with only replacing the rear drum bearing, but if it has been going on for some time you should replace the drum bearing kit part # WE25M40. Also be sure to check that the front drum slides are ok, especially the one on the left side of the front drum support, as this one wears out faster. Drum slides #
WE1M481 and
WE1M333 and if front support frame is worn so that there is nothing left to hook the slides into you would need a
WE3M26.

there are two possibilities for this question. 1) there is an idler roller that give the belt the correct tension . unplug dryer and remove idler roller see if it spins freely if not replace it @0 there are two drum rollers in back of machine thatdrum rides on remove drum it's self explanitory how to remove drum and very easy also. you can roll these wheels and check for free movement visually check them ,one or both should be worn out or the bearing in the wheel has failed before putting old or new wheels back sand the wheel shafts to get any gunk off them and that's about the only thing that can make a dryer squeek

It could be the rear drum bearing, or the belt needs replacement.
