Product review (5 stars): Didn't take the dryer apart like the videos tell you to do
Replaced these myself, took about 15 minutes.  Didn't take the dryer apart like the videos tell you to do.  Just unplug it and you can access right through the dryer door.  Take the screws out and put these new ones in.  Tools used were needle nose pliers, phillips head screwdriver.  Have a shopvac on hand because once you take the screws out you'll have access to the dryer lint tray bottom.  Lot of lint crap there you can finally reach and clean out.
