MK4 ABS rear tone ring replacement question

[amit9]

The abs tone ring on my rear right wheel hub is warped and one section is raised. It's rubbing on the bottom of the abs sensor and has caused it to fail (abs light on).
Is it better to replace the entire hub that has a new tone ring and nut, or is it ok to replace just the tone ring (save a few $)? If the hub is out, is it too much effort to remove the old tone ring and install the new one?

Thanks.

In theory the tone ring is available separately but I suspect you might find it difficult to source compared to the whole hub since it's not really cheaper if you are paying for labour.

The hub has to come off anyway, might as well just replace it.
