If its a F-150 its no doubt a 9" Ford if its the original axle but if it is the factory axle your looking at the famous Ford 9 inch. Pretty easy to tell if its a 9" if it doesn't have a differential cover plate on the back of her and she has a drop out section on the front.

its not on the paper he gave me but that doesnt mean anything, once again i havent looked at it yet so i'll check it out 9 inch is what he was hoping.. which leads me to my next question why do the F-250's (or at least mine) have Dana 60 rear ends and the 150's got 9 inch? thanks.

Dave, the reason they put the 60 in your F250 is because it's a heavier and stronger axle. That's really the big difference in the two trucks
If you put a ford 9 inch in your F 250, i suppose you'd have a F150

Dave, The 9 after the 50 represents it being a 9".
The other numbers are for foundry,bearing,& date associated.
That's all.

Dave, I agree with Dennis, there should be something in front of the 50, and most likely a 3.
