Jeep Grand Cherokee WJ Speedometer Calibration - SpeedoDRD

As you may or may not know, the WJ gets its electronic signal for the speedometer off of a rear wheel speed sensor. This is part of the anti-lock brake (ABS) system. Simply changing out a gear in the transfer case is not an option. SpeedoDRD is the only solution I have found. www.12oclocklabs.co…

This is the easiest way to calibrate the speedometer a Ford Ranger. Use this method if you are needing to remove the needle so you can work on your odometer, or circuit board for any reason.
