1989 ford and i just got done putting a new front end on cause some of my ring gear teeth were broke and my 4x4 wasnt working. So i switched it all out for another f250 front end that i baught thinking it has to be a 4:10s, so i looked at the ring gear on it and it has the same exact amount of teeth as on my old one but i forgot to see if the pinion gear was the same, my gear's are 4:10's in the rear and after i put it all back together my front wheel's want to jerk and act like there kicking back while driving in 4x4. Could the pinion's be diffrent? thanks
