can't find this part anywhere, help!

i have a picture of a gear on the front right wheel that gives a signal to the abs wheel speed sensor. i can find the wheel sensor to order, but cannot find the gear anywhere, it has a crack and causes the abs to deactivate since there is no signal. does anyone know if it can be ordered? i cannot check with a dealer easily, i am overseas. i can send you a picture of the part as it is installed if this helps. thanks!

That ring is a ferrite ring and very fragile. The only way I am aware of to get a replacement ring is to replace the CV joint or halfshaft.
