I have a F150 with the sevenlug axle. I found out its a 10.25 Sterling semi-float rearend, same as used in the F250s with eightlugs. Does anyone know how hard/expensive it would be to change over to eightlugs? I hate having such an oddball rim and think it would be boss to have an eightlug F150.

well the rear would be just a matter of swapping the axles but you cant just do that on the front unless you do a SAS. wheel adapters would be the easiest thing but a lot of people don't recomend them.

I figured the rear wouldn't be too bad. You don't think I could just swap the front out without messing with hubs and such? I wonder if it's possible to go to locking hubs like on the older 4x4s. I know I wouldn't be able to engage it from the cab, but I'd be ok with that.

You're half-right on the axles.

The 10.25 8-lug axles you speak of were used on the late 80's early 90's F-250 and F350s, but they were FULL-FLOATING, not semi-floating axles. They had no c-clips, just hub bolts. Completely different set-up.

I'd think you could find semi-float axles that would jive, but then what about the brakes, rotors, calipers, and all that stuff. Then you'd need to reweld spring perches and shock mounts. I agree it would be cool, but not worth the work or money for one lug nut IMO.

The light duty F250s used a semi-float design. I talked with a ford mechanic about this a few days ago. He said swapping the rear axles wouldn't be an issue, but the front is totally different. Since the F250/350 uses a solid axle I would need to do a lot of fabricating to get that to work. I'm not ready to do a SAS quite yet, so I'm going to get by with my 7s for now

To find a LD F250 rear end u will have to go to tiny drum brakes in the rear. You might as well just go all out and find a wrecked SD and go to the newer axles with disks.
