Hi there, i have just changed the nearside rear wheel bearing. The old one has an integrated reluctor for ABS sensing. The new one has a magnetic rubber ring. ABS light is now on. Do I need to change the sensor? Any advice gratefully received. Thanks Grant

Ideally use scan tool to read wheel speeds when moving and see if all similar/ which one not working.

Was the brown magnetic hub ring damaged when fitting? Or the abs sensor?
Did you disconnect /reconnect abs sensor while replacing hub?
