Product review (3 stars): It would be better using a locking bolt on the shaft
This is an exact match for what comes from a Whirlpool-based dryer.

Yes, you will have to destroy the old wheel to remove it.  A lot of people blame the plastic wheel, since it tends to disintegrate, but the reality is a little bit more interesting.  I put an impact wrench (battery powered) on the shaft, since it doesn't generate torque.  And when I did that, the blower still did not come off.  Instead (and you'll think I'm making this up).  The front of the shaft snapped off.  See the picture showing that.

The 2nd picture shows that metal sleeve attached to the shaft.  I tried using a vice grips on that metal sleeve and one on the shaft, and it even with leverage it would not budge.  I did not try penetrating oil or heat.  But that seems a bit ridiculous.

So you'll need this every time you replace your motor, which makes the job a lot bigger because you have to take apart the entire back of the dryer.

When I replace it, I put high-temp anti-seize.  I don't know if that will work, but I hope the motor doesn't break again.

I'm only rating this average because the design of the blower assumes the motor will never break.  It would be better using a locking bolt on the shaft.
