Where is the speed sensor on 1999 dodge durango?
On my 1999 Durango 4X4 with rear antilock brakes, the sensor for the antilock brakes, the speedometer, and the automatic door locks, is located on the rear differential. It’s a magnetic sensor that has a retaining device, and slides into the top of the differential case. Getting the old one loose was challenging. The replacement went in pretty easily. Unplug the wire, remove the retaining hardware, pull or pry the old sensor out, put the new one in, replace the retaining hardware, and plug it back in. This instantly restored operation of the speedometer, and cleared the antilock brake fault. I didn’t have to disconnect the battery to accomplish this, though for best safety to the computer, this would probably be a good idea. Also, supporting the truck with jack stands on the frame, so the differential is hanging off the the springs, greatly improves access to the area of the differential you’re trying to get to. Even better is to get it up high enough to sit/stand under the truck.
