what grease or whatever is shown in the video should i put around the sensor when installing it?
christopher g on Feb 25, 2016
BEST ANSWER: You can use dielectric grease if you would like, it is made to keep connections strong. It is a personal preference, and not necessary.
I have installed the sensor pair as instructed and tested but my antilock breaks continue to activate at 5-10 mph. What other things could it possibly be?
Lee K on Jul 12, 2017
BEST ANSWER: The other possible things could be the bearing being out of specification causing an incorrect reading.
