Depends on which TTB it has... the F-250 comes with either the D44-HD or the D50. D44-HD has the standard 297 joints and 1/2 ton lockouts. D50 has the 1350 joints and D60 lockouts/hubs/brakes.Flatty said:Well I am getting ready to do an axle swap, and I heard I can get rid of my TTB front end. It is a TTB out of a 91 F250 Diesel. This means it has all the heavy duty outside stuff. Is this worth anything to anyone? If so, how much?
