When doing this swap is the 05+ rear axle needed as well, to keep from having to use spacers on the old rear axle with newer wheels?

 

That is correct.

 

Thanks, I will be welding in plate steel to box in frame behind the engine cradle.

 

If your keeping your original front ABS you'll need to cut a hole in the left bracket behind the cross member in order to route the rear brake line down thru the frame properly.
Front brake lines will have to be modified to run behind the cross member, the track bar and steering stabilizer mounts make rerouting the line in front of the cross member nearly impossible.

My 07 donor had the ABS near the firewall that would have required lots of wiring relocating in order to use it on my 04 so I modified the lines to work with the 07's front frame.

 

How did you guys do the sway bar as it is behind the axle on leaf spring trucks and in front on coil spring trucks? Looks like the welded a bracket to the frame. I have an 05 excursion and am ready to do this but don't want any delays right in the middle. Anyone have an 05 to 08 rolling chassis they want to sell?

 

The mounting holes for the sway-bar-in-the-front option are there. Just use the mounts/bushings from the donor vehicle. It all bolts right in since the frame is set up for 2wd options at the factory, and the 2wd 05 trucks had the sway bar in the front.

Lots of 05+ axles for sale down here.

 

I swapped out the front frame section on my F-450, the engine was out and it was simpler to swap the entire front section than to swap the parts.
Not sure about F-250-350's but the steering box for the F-450-550 was changed in 05 to a beefier box with larger mounting bolts and a different bolt pattern making it nearly impossible to swap to my 04 frame.

 

Where is down here? Have trailer, will travel!

He has about 7 more sets left.

 

awesome! Thanks!

 

Has anyone put together a list of fasteners and miscellaneous parts needed for this mod? Also does anyone know if a 2008 f250 steering box will fit on a 2005 Excursion.

Wrong thread

 

Does anyone know if suspension off a 2009 F250 will mount in the same fashion as the 05-07s? I will not be swapping frames just suspension components.

Are the axles the same for all superdutys regardless of engine size?

 

The '08+ rear springs are longer, and they cannot be used on your X without modifying your X spring mounting points.

The steering gear box on the 08+ trucks is different due to the input shaft change. You will need a gearbox from an 05-07, and likely the pitman arm as well, unless you get the whole shaft from the steering column off the 08 and splice it into your old one.

The axles 05+ are all the same regardless of engine, so there is some good news for you.
