Admiral dryer Squeaks

We bought this dryer from Craigslist and therefore have no idea how old it is. It drys fine and runs fine (timer is out, but I don’t really mind that). The problem is that it makes this awful noise that comes and goes as dryer is running. I need to do laundry but with my husband sleeping during the day (he works night shift) I need something that won’t keep him up! Any help would be wonderful. Thank you!
