Squealing noise which got worse over time

The dryer started to make a squealing noise which got worse over time. I went on the internet to research what might be the cause of the problem and came across your website which pointed to drum rollers, idler pully wheel or belt as potential causes of the problem. I watched the installation video on how to dismantle the dryer and upon removing the tub discovered it was the idler pulley wheel and bearing had broke. I ordered the parts and figured I would replace the belt while I had the dryer apart. The parts arrived the day after I ordered them and I was able to fix the dryer in about 45 minutes thanks to the video your website provided taking someone from start to finish in dismantling and replacing the parts that I had ordered. I won't explain how to repair it because I would advise someone who hasn't taken a dryer apart, like me, to watch the installation video. It was easier than I expected and will come to this site in the future for appliance repair problems. The dryer works great and I will get many more years of use out of it.
