It could be a wheel bearing,front Diff, transmision, engine accessory, transfer case, rear axle. You need to drive again is noise faster with engine rpm (speed) or faster with truck speed!!!!!!!!!!!!!

You need the speedo calibrated, if that is not the cause then either the speedo is defective or their is some unlikely problem with the speed sensor.

If tranny is manual shift you may have a bearing and or bad gear. Try changing tranny fluid. Check manual for correct fluid may use tranny fluid rather than gear oil. I recommend using Royal Purple fluid or gear oil. This very expensive but will slicken up the shifting and extend bearing and gear life.

Ok the output speed sensor and the vehicle speed sensor are not the same sensor.The output speed sensor will be on the tailshaft housing of the transmission or to the rear of the transmission case if it is a 45rfe(5 speed auto).The vehicle speed sensor is in the top of rear differential housing.Be sure and douse the sensor with wd40 before you try to remove.Dry oring will cause sensor to stick and break and that can be a headache.Good Luck!

Whining noise

Can you make the noise happen with your foot on the brake, trans in gear, and a little throttle? And does it go away in park & neutral? If yes to both questions you probably have a faulty thrust bearing in the torque convertor. If no to both questions you like have a faulty "input drum to pump cover thrust bearing." Either way the problem must be repaired ASAP or when the bearing fails it will be at the worst possible time, like in the middle of an intersection with a firetruck bearing down on you.
