when I shift into 4wd low--rpm's get high, but truck barely moves--2012 f150
also when going up a slight incline (my driveway) and turning- the front end makes a racheting sound--in two wheel drive
if you have it in 4x4 low its running a low gear thats why you are not moving fast 4x4 low is not made to go fast its just a low gear
Use manual shift and you will have gears 1, 2 and 3.
