Correct?What I mean is that the outside frame sees the geometric center shifted.If the angular momentum vector is shifted to the geometric center then what happens when the axle, now off center, gets accelerated?If you read my comment, I said the momentum doesn't have a location, so the nonexistent location cannot be shifted anywhere. Any yet I see at least four references to the location of the momentum above (bolded), which makes no sense.It not having a location means that I can apply a certain torque anywhere on the object and it will have an identical effect on its angular momentum regardless of where the torque is applied.Similarly, I can apply linear force anywhere on the object and it will have an identical effect on its linear momentum regardless of where the force is applied. That's what it means for momentum not to have a location.

[momentum] is a vector ... composed of direction and magnitude, but not location.
