Will this tub fit my washer?

Only if your model number is listed as compatible. The tub is shared across many Whirlpool, Maytag, Kenmore, KitchenAid, Amana, Roper and related models, but it is not universal. Check the model plate on the lid or back of your machine before ordering.

Is this a genuine Whirlpool part?

Yes, it is sold as an OEM part built to Whirlpool specifications. That matters for the tub's mounting surfaces and bearing seat, which aftermarket copies sometimes get wrong.

What else do I need for the job?

Plan on a new tub seal and drive hub or spanner nut, since those are usually replaced at the same time. You will also need basic hand tools and a way to lift the spin basket out.

How hard is the installation?

It is a major repair. The cabinet comes apart, the basket and drive components come out, and the tub is lifted free. Many owners hire a technician for this one.

Why does my washer need a new outer tub?

Common causes are a crack from an unbalanced load, rust-through, or a failed seal that lets water past the bearing area. A visible leak under the machine is the usual symptom.
