This site does have problem with some Sears numbers. It seems Sears almost produces a different model number for every single machine.

The part number you listed does not seem like the right part. I would call the APP parts department and order from them. If they cannot confirm your model number you can tell them that you have a Frigidaire Gallery front loader manufactured for Sears.

Replacing the part is pretty easy, here is a service manual for your model. I would replace both while you are in there. Do it right and do it once is my motto.

Just so you know this model is prone to a bearing failure in the tub, so check to make sure yours is ok. If that fails the repair is usually so expensive and difficult that the machine is usually replaced.
