Removing ABS Sensor

[volcar]

I recently acquired a set of used rear wheel knuckle with hub & bearing they also have the ABS sensors installed. I have attempted to remove them (ABS sensors) from the knuckle by removing the single bolt that holds it in place, however, upon removing the bolt I am unable to remove the sensor it is stuck in place. I am wondering whether any of you good folks has ever had to removed the rear ABS sensor & if so can you advise on how to proceed.
As usual all comments/advice & suggestions will be greatly appreciated

they are a tight fit, you should just need to tap them out ...
