Product review (5 stars): Five stars is not high enough
What an awesome product!  Simple, easy to install, great directions.  How many perfectly good dryers are thrown out because their owners didn't know about this kit (or were afraid to try it)?  My 15 year old Whirlpool 29 inch dryer developed terrible rumbling and squeaking noises.  I priced new dryers and was shocked.  $600/$700/$800 or more for a DRYER?  Are they kidding?  Faced with spending $700 on a new dryer or $16 on this kit, the choice was obvious.  My dryer came apart easily.  Remove two screws holding the filter assembly to the lid.  Next, pry up the lid in the front (it is hinged on the back).  Next remove two top screws holding the front cover, then lift and pull out.  Remove the belt from the motor and pulley, then remove the drum.  Replace the support wheels (it's easy).  Then reinsert the drum.  Have someone hold the drum (or use bungee cords on the top like I did).  Thread the belt through the pulley and on the motor just as shown in the picture.  Reattach the front cover, then spin the drum manually a few times to make sure the front and back seals seat properly, and the belt is rotating in it's original position on the drum.  Finally, lower the lid (snap it in the front) and reattach the filter screws.  Then plug it in and try it.  Amazing!  No more rumbling, no squeaking, just beautiful, steady, quiet rolling, just like 15 years ago when it was new.  Best investment I have made in years!
