So on January 1st I bought a 1996 Ford F-350. Three weeks ago as I was going to do a delivery the passenger side axle shaft decided to take a little walk. Now I have to replace all the bearings and seals on the rear axle. Does anyone know what type of axle is on the back? My old 1986 Ford F-250 had a Dana 70 HD. My F350 not a clue!

 

There may be a tag on the axle housing. Some are held on with one of the cover bolts and some are welded to the rear of the axle housing on the passenger side to the right of the banjo housing.

 

There should be an axle code on the door pillar or sticker. Post it here , or just punch in on google "Ford rear axle codes" and it should show what you are looking for.
