The idler pulley bearing had gotten squeaky and bearing grease did not solve the problem

I replaced the idler pulley and arm. I had broken down the dryer before to find the source of an annoying squeaking problem. At that time I lubricated the bearing with some hi-temp bearing grease; that worked for awhile but was not permanent. Needing to do it again, I ordered the replacement parts off the PartSelect site using the provided diagrams and parts. [Very nice.] I then checked the videos tagged to each of the parts to make sure I was doing everything right. Everything went back in perfectly. The site is very useful and very helpful. Thanks.
