My dryer started squeezing something fierce. I figured it was the belt or an idler pulley and ordered a kit. When I pulled it apart I found it was the idler pulley, but went over everything else, making sure to lube everything and more importantly, vacuum it out! Holy crap there was a lot of lint in there! For sure it was a fire hazard! I’d already started cleaning the front when I took this pic. You guys may want to vacuum yours out!
