Do you have the factory specified sizes for the tires & rims? If you have oversize tires that will do it. If everything is factory fit stuff I would look at the Vehicle Speed sensor.

Speedometer is 10mph off . if it says 50 the truck is only going 40


Your tire size is likely not the original tire size for that vehicle (likely larger than original). Take it to a shop and have them re calibrate the speedometer.

1990 honda accord speedometer inaccurate


The speedometer sensors on these cars can go bad sometimes and often, and also low power steering fluid can effect their readings. Check your power steering fluid level and see if that is the cause, If not, the sensor is probably worn out a bit.

The speedo in my 95 mustang Gt Is 10 miles an hour fast


A vehicle speed sensor that is starting to fail could cause this, or less than likely bad wiring or connections, or yes, a bad cluster could do this... But how exactly did she notice the speedometer was 10MPH fast?? There are no real accurate speedometers in vehicles (Don't get me wrong they shouldn't be off by 10MPH) but there is a 5 or so percent difference high or low in many vehicles even with stock powertrains. I've plugged in with a diagnostic scanner on many vehicles and the dash speedo shows 60MPH, but the electronic speed readout on the scanner reads as low as 55MPH or as high as 65MPH
