Yep, except the claim their isn't one made for f350 rear. I guess I'll have to get out the micrometer and order one myself.

 

National Bearing via OReilly lists this one for an F350 but not sure what axle you have but this might be it.

They may not have a kit that says "2001 Super Duty" but they will have a sleeve that will work.

 

I have what should be an easy way to get the answer

Ok, being a novice to f350 suspensions, be kind. The problem was the backing of the previous seal was still on the spindle! It looked to me to be a mating surface for the new seal. Once I got the old off, the new went on easily. I can now change an axle seal in less than ten minutes!

 

Good to hear that you got it.
