Excuse me if this is a dumb question, but the pic of the "old" axle on the trailer looks to have drum brakes. Don't all Super Duties have disc brakes front and rear?

Also, interesting thread. Good work by all.

Steven,

I'm not sure about the brake lines and power steering lines. However, when changing from front leaf suspension to front coil suspension, I have read a few threads on forums mentioning the need to change the power steering gear box from 1999 - 2004 to the 2005 - 2007. I looked on Ford parts website ( fordparts.com ) and it shows different part numbers and weight, but photos and dimensions are the same. I would contact Red Head Steering Gears in Auburn Washington. They are the experts. Evidently they developed a proprietary process to build bullet proof steering gear boxes. Ask them if the steering gear boxes are different between the 1999 - 2004 and 2005 - 2007 model years. I would also search the internet for aftermarket hoses. You might check with DieselSite in Florida. For brake lines...not sure about that. For brake lines, I would recommend Crown performance.

This thread caught my eye because I have thought about building a 2002 Ford F350 Crew Cab 4WD.....setting the cab, front clip, bed along with 7.3L engine and 4R100 transmission onto a 2005 - 2006 chassis, frame, and suspension...and installing a Carli 4.5 inch suspension system. I previously owned a 2002 Ford F350 Crew Cab 4WD SRW ( LB - 172 ) and I think it had just rear anti-lock brakes...although I might be mistaken. I now have a 2006 Ford F350 Crew Cab 4WD SRW ( LB - 172 ) and it has front and rear anti-lock brakes. This truck has all the parts and upgrades offered by Bullet Proof Diesel. It also has a BTS ( Brian's Truck Shop ) built 5R110. It would be interesting to learn and obtain information about converting rear anti-lock brakes to 4 wheel anti-lock brakes. No doubt there are threads discussing this change.

Anyone who's done this conversion, what radius arm brackets did you use to mount the rear of the arms to the frame?

I've got a 2007 4x4 front axle to put on my 2x4 Excursion and would like to use my original radius arm mounting brackets from my twin I beam front suspension. That would save me $400-$500.

Or were you forced to use the newer radius arm mounting brackets?

New guy bumping this thread instead of starting a new one. Same questions as Steven Barnes...

Can anyone confirm the metric size and length of the bolts for the 05+ steering box on the 99-04 frame?
And do I need the pressure or return line off an 05+ truck?

Thanks!

I know for sure it is the high pressure line that goes from Hydroboost to the steering box that needs to be changed to 2005 hose.

I do not remember the bolt size- it has been awhile since I did the swap. If you look at my pics I went with a slightly longer bolt than the 99-02 and I believe it was 2mm larger diameter.



***ALSO TO RETAIN ABS***

I used the original 2002 rear sensor and installed it on the 2007 rear axle.

I had to swap the abs sensors in front axle to 2002 4WD senors. Apparently 2005+ went to a different style ABS. The earlier sensors bolt in. I just moved the 2002 grommets on the abs sensor wire to same position as 2005 wire so I could follow same wire routing and keep it tucked out of harms way.

ABS works 100%. No ABS light.

Switching from leaf to coil is way worth the effort!
Like night and day difference and well worth it. Anyone who tells you otherwise, doesn’t have a clue what they are talking about.

Awesome!! Thanks for the feedback!!

And I've seen another post where the guy welded 1/4" shims to his radius arm brackets. But he was doing this swap on an Excursion. Is that an Excursion frame thing? Are the front of the frames different between the Excursions and the 99-03 Super Dutys? Will I have to do anything like that to my 4wd 2000 F350?? Or will the brackets fit flush against my frame as-is?? Thank you again guys!!

Unboxed frame.

Great info fellas! I have all my parts together to do the swap.

I was talking to a buddy an he said he would be slightly concerned about the unboxed (c-channel) frame section were the shock tower will be installed on the 99-04. Just a concern.... by no means saying its going to fail. Since this year range does not carry the weight of the front end there and is dispersed on a leaf, I assume they saw no need to box this part of the frame. The 05+ sure enough has the frame boxed above the axle and around the shock tower. Has anyone who has been running the conversion for a while had any issues with this?.... cracks, bending, twisting?


thank you!

thank you!
The newer frames are only gusseted right where the frame and rear of the engine cross member meet. The area where the coil/shock buckets mount is channeled just like the leaf spring trucks. They are both boxed in front of that (where the steering box mounts). I've only had my swap done for 8ish months but I have 2'000+ Baja miles on her. Just hauling ass over crappy roads and chasing/pitting in remote areas down there (didn't want to sound like I'm actually racing/prerunning this beast at race speeds lol).

ZERO regrets about the swap btw. Running 37s on the Carli 4.5" coils and caster adjustable LewisBuilt radius arms (bad ass units)....

I was wondering about this also I just completed the conversion and was wondering if the frame boxing was needed?
