im looking at buying a 95 explorer and it has an abs problem. when the truck comes to a stop , just before the wheels stop rolling the abs activates. i know the rear sensor has been replaced. im sure it has a bad sensor i just dont know how to find out which one is the culprit. any help would be welcome. thanks..

Welcome to the forum!

If it's a sensor issue, they can be checked with a simple voltmeter. However, an oscilloscope would be the better tool is you have access to one. You could also go with a professional ABS scan tool to determine the issue as well.
