Product review (5 stars): Worked great in our Whirlpool front loader.
Worked great to remove rollers squeeking.  Our front loading Whirlpool required the removal of the top cover and the entire rear of the machine (not front panel) to get the drum out to replace the rollers and belt.  Repair took about 1.5 hours including extensive air compressor time to clear out all the lint!

The original rollers were red (as in the amazon picture).  The replacement rollers I received were black.  I was initially concerned I received the incorrect parts but they worked fine for the 27" drum in our front loading dryer.  Also, the white, tensioner pulley in the diagram above was slightly larger than the original but it works fine.

Great price.
