Front ABS Sensors
Motorcraft BRAB30 on '93-96 Broncos only. Clean all metal filings off to improve signal quality.
To remove the spindle, remove the sensor bolt (6-point 8mm-5/16") and the shield bolt (12-point 6mm, but a 12-point 7/32" can be hammered onto it) from inside the steering knuckle. Once the spindle is off, drive the sensor inboard HAMMERING ONLY on the tube around the bolt. Clean both sensor bores thoroughly with a steel bore brush, and clean the sensor & its bolt tube. Apply anti-seize lube to both bores before reinstalling the sensor, and to the spindle bore of the steering knuckle.
Whether the spindle was removed or not; clean its sealing surfaces thoroughly.
