Maytag Performa dryer squeaking

I think my Maytag Performa might be on its last legs. For over a year, it would squeak a little, but not all the time. Now, when you turn it on, it squeaks/squeals all the time, sometimes very noisily. I’m afraid it might be bearings. Is there any hope? Could it possibly be a belt? Do I just use it until it dies, and if so, how long does it have to live?
