Is there any way to test to see if the magnets are good. I am in the process of replacing my grease seals, an now would be a good time to find out about these magnets. Thanks for your input.
First do a resistance test. then, to do it right, you have to expose the magnets and inspect thier wear indicators. There are dimples on the face of the magnet and when they are worn away, it's time to replace them.
