    Hey there guys I have a kenworth t600 2007 cat motor. Couple of weeks ago all of sudden speedometer on my truck started jumping. Even when I am idling it jumps and also while I am driving. What do you guys think what could be the issue behind it? Look forward to hear back from you guys. Thanks

    Check output shaft / driveline yoke for proper torque

    Check air gap on sensor for foreign debris it has a small magnetic tip on it for the Hall effect sensor. Just takes some small particles to screw with it. Also May want to check wiring harness for any corrosion or frayed wires
