Product review (4 stars): great deal from this seller, pain to install
The install instructions provided are those provided by the manufacturer.  They are horrid!  Type is small, vague, incomplete.  If left to those instructions, I would have returned the item.

Do yourself a favor - watch the install video at [...], Door Boot Seal Replacement (part #134728400) - Frigidaire Affinity Washer Repair.  This made the process so much easier!  There are more steps to do it easily - invest a couple minutes and avoid getting stuck without being able to finish.
