Product review (5 stars): Frigidaire Dryer Rear Bearing
Dryer started making a horrible screeching sound and I goggled the problem which was the rear bearing.  Just watched several youtube/yahoo videos and removal/installation probably took 2 - 2 1/2 hours.  Would probably take 45 minutes if I needed to do something else now that I know how to get in the dryer :)  Great product and fixed the problem.
