Product review (4 stars): Solved my squeaking dryer problem
This part solved a huge dryer squeaking problem we were having. It was not hard to install, but you will likely have to take the drum out to do it. Note that you can just buy the pulley alone without the arm. While you have the dryer apart, you should consider replacing the rear drum support bearings, the drum glides and the drum drive belt. These parts are not expensive, or hard to install (once you have the drum out). Replacing them now may save you a big headache later.
