2005+ Axle swap on an OBS Ford Truck!
HTML-код
- Опубликовано: 14 окт 2024
- I'm going to outline a 2005 and newer axle swap on an OBS Ford pickup in this video. The swap is completed enough on the truck in the video to demonstrate the install. I've logged over 200,000 miles on my other truck that has been 2005+ axle swapped without issues, and the truck in the video is done the same as the other one I did 13 years ago. If you found my video and/or description helpful please like and subscribe to the channel for more OBS content!
This video is directly showing the lowest you can be on an 05+ Swap using unmodified OEM Components. There are a million ways you can configure this swap, but this way is using as many OEM Components as possible. This way, when you purchase a rolling chassis, it gives you the ability to use as many parts as possible without having to buy more parts elsewhere. It also gives you a great baseline to start with, as the swap gives a little bit of lift, so you'd be able to adjust your height, up or down, based on your needs by purchasing other suspension components such as lift coils, or lowering coils etc.
If you're looking for a specific piece of information related to this video, please comment, and I will respond with an answer for you, please browse the comments for a question before asking.
Some details about the swap:
-2005 to 2016 Axles are the only ones with a VSS in the rear axle.
-All bolts are 1/2" for bracket installation.
-The 99-04 Leaf springs are not required for the swap, you can run your OBS leaf springs, or any setup you'd like.
-The Transfer case is also not required, but then you're requiring a conversion joint (Neapco 2-3050) for the front, and possible driveshaft modification, and the rear driveshaft will need a flange (Spicer 3-2-1859, for a 1350 joint) for the rear axle installed on the driveshaft.
Something to keep in mind when purchasing pre-built parts, and their track bar mounts will be designed to use their respective coil buckets.
SKY Coil Buckets add 1" of lift
RYD Coil Buckets add 3" of lift
If you decide to purchase a Track Bar Mount:

Ill cover the transfer case install, and rear leaf install in another video, as those aren't required for the swap.

Well put together machine! Love the New SD wheels. Once you get it painted and finished, that rig will bring high dollar if you decide to sell it. Awesome work!!
Thank you! I wanted to do it right. And make it what I needed. I hope I never have to sell it. But you never know!
You have a great informational video. The overwhelming bent for these conversions favors the lifting of the truck. Thank you for recognizing the needs of those who wish to maintain a sane center of balance for highway driving. I concur with your (and, obviously, Ford's) recognition of the superiority of coil over leaf spring suspension. Still, I remain disappointed with the move to the Super Duty axles with their metric bolt pattern and [front] unit bearing hubs. In my experience, traditional rebuildable/greaseable bearings are superior to unit type.
Thanks!
I’m glad you enjoyed the video!
The unit bearings are not as bad as people make them out to be. The 2005+ ones are much more resilient than the 99-04 ones.
Doing this swap for the benefit of a solid axle and better ride justify it IMO, everything else is a bonus, I converted my 2wd and this was essentially the same cost as an OBS D60 except better in so many ways. otherwise its a plain looking truck kept it as low as possible lol, still fits in the garage.
Great video. I'm not using RYD because they have horrible customer service. I actually found a guy out of Arizona, Blowing Diesel Designs, who offers what I feel is the best designed "kit" if that's the route folks want to go.
I’ve seen multiple “in-house” kits offered by guys over the years, and I’m not lumping the one you recommended into this because I haven’t seen it. But, the ones I have seen have been poor quality and poor customer service. So bad to the point that people never got their products and the products that did get sent out weren’t trust worthy. It would be nice to see some more quality components show up on the market. RYD has its pitfalls, that is true, which is why I recommended the SKY one in this video.
Nice build Garrett 👌
Thanks 👍
I noticed you are running the e350 7.3 powersteering setup I did same swap with hydrobooster conversion running a fsuperduty hydrobooster and master cylinder used the 6.0 power stroke pressure lines and my own return line off the steering bow to e350 resivour great setup over stock
Yeah, I run a van setup on the trucks, its an easier setup to run, and the remote reservoir makes it nice. I was able to use the stock F-Superduty lines with a little massaging.
Very informative, keep up the videos!
Thanks very much this helped with my swap
I’m glad it helped!!
Lots of good info thanks man, What’s the measurements on those front buckets?
It’s in the comment section somewhere. I’m not near the truck to measure it at the moment.
I have 5 inch on my obs and it fits perfect but I also don’t have the axle swap but it fits good and looks good
How old is the 5”? Diamond eye changed the bends on the 5” system a few years ago and that’s why they don’t fit as good as they used to. My original 5” system fit great on my 1995.
Bet youre gonna be using that plow tonight or tomorrow haha.. good storm headed your way
I really could live without using that plow ever again. Haha
It is indeed an awesome build and info! Do you consider this posible done on a 2001 Chevy express 3500 with the parts that you picked?
Thank you! I honestly have zero knowledge about the Express vans. But anything is possible with the knowledge. The 05+ axles are useful across many platforms though!
@@GarrettsOBSGarage I only have to check on the measurements between coil buckets cause to me look pretty close with the ones already in express chassis but the rest of it I'm sure can be worked out like in yours
@@alb2571 if the width is close. You should be able to make it happen!
Great video, thanks for the information! What are the measurements on those front buckets?
I’m not near the truck. But it’s been posted in the comments elsewhere.
Do you have a recommendation on alignment specs? I’ve been having an issue with wandering steering on rough roads with my sd axle swapped obs. I’m currently at around 4 degrees castor, and .12 degrees toe in. Thanks, I appreciate all of your videos!
I’ve always done 1/8” toe in. And I have the trucks set at 4.5° negative caster if possible. Otherwise, the factory spec is around 2° negative.
If you’re wandering bad, you may have something worn out like a steering box.
Super informative, thank you for sharing. Are there any benefits of using any particular year of axles ranging from 05-16?
There are subtle differences between the years. 05-07 is my favorite year range because the coil buckets on the frame are flat, in 2008, they added a large dimple on the back of the bucket which needs removed to use them on the OBS. The rear axle shock brackets bolt on, which makes it easier to flip the one forward. The steering box, should you use it, bolts right up to the OBS steering shaft. I also like the way the front sway bar mounts to the axle. So the 05-07 is the most desirable in my opinion. However, the rear pinion bearing in that era can be problematic due to its size.
nice video… why didn’t you keep the old 94-97 manual transfer case? i thought you could keep that and not have to change?
The reason for the change was to run the 05+ front driveshaft. The 1356 from an F350 isn’t very hard to find, but the front driveshaft is. The 4407 for an F350 is very difficult to find. So, to run the 05+ shaft, I wanted a front flat flange on the transfer case. So it was easier to swap to the 99-04 transfer case.
Thanks for all the information and knowledge. I was wondering if you ever put bolts in the bottom of the coil buckets on this truck or the other one thanks
Ideally. You should. However I don’t think I put them on the bottom of this truck. Or my
95, and the 95 has about 250,000+ miles on that swap now without any issues.
@@GarrettsOBSGarage 10/4 just checking if you ain’t had any problems I probably won’t worry about them either on mine thanks for all the info
@@johnhancock7289 you’re welcome! If I do it for someone other than myself. I always put them in.
Great video. I’m looking to straight axle my 83 Bronco.it didn’t look like you had to do any cutting on the front cross member?
Do you know if stock coil buckets will work with Superduty coils? Location size etc? Thanks for any information.
No cutting involved!
And I would NEVER use OBS coil spring mounts with SD springs. The top of the spring and retaining system is completely different and in my opinion unsafe to use the SD coil in the OBS bucket.
If you want to do the 05+ swap, always use the correct meshing parts to ensure it’s 100% safe.
99-04 gas 4sp or 99-03 diesel. The 5R uses a 34 spline output but the E4/4R are 31. Had a guy get pissed at me when he bought an 04 6.0 case and it didn’t fit his E4, like sorry guy i didn’t know what you were putting it in lol
Yup! A very specific case to find. Most guys don’t know there are a lot of differences.
Working on my swap and have an 05 steering box I was gonna sell cause I didn’t wanna deal with the lines but if you have the info that would be nice! Would you say there is a difference between the 05 and my 97 steering box? My last axle swap I kept the 97 box too so I’ve never actually felt the 05 box in this model year truck.
Thanks for all the info and walking us through this! Makes it so much easier for us DIY guys! Great content!!
So, its a matter of preference for the box. If you decide to use the OBS box, you have to have your pitman arm reamed out. Which can be an issue if you don't have a machine shop to do it for you. RYD Sells the pitman arm already reamed if you decide to go that route. I've been told that the 05 Box has a little more "throw", and turns sharper, and also turns faster than the OBS box. I haven't driven the truck with the 05 Box enough to get a good feel for it yet.
If you choose to use the 05-07 box, you have a couple modifications to do. My instructions are setup for the hydroboost setup, since all of my trucks are hydroboost. I haven't done one with a vacuum setup. This is how I did the lines on the truck in the video, and I haven't seen what others have done to complete this task, but I know that this works.

I wanna do this swap to my 97 f250. Are the coil buckets 05 factory or aftermarket? Will the transfer case you installed mate up to the zf5? Thanks man!
The coil buckets are factory, and if you have a ZF, you’ll need a custom crossmember. I believe RYD makes one.
How did you hook up your vss on the axle? I went with a new motorcraft vss in the axle and a ford factory vss pigtail and wired that onto my old harness but I don’t have a speedometer. Just looking to find out how to fix my issue lol
I used the OBS sensor. Do you have an odometer reading?
@@GarrettsOBSGarage my odo still seems to work but I haven’t payed close attention, I’ll drive it tomorrow and see if the mileage increases
@@Some_Truckery if the odometer is still on. Try unplugging the ABS module behind the glove box. Larger black box. See if the speedometer works then.
When you did the rear axle, did you have any issues getting the centering pins lined up?
I did not have any issues with the centering pins, no.
Ive been wondering how these fit with the ultramount. My other truck has the rsk sd spring and that wouldnt work. I need to do this
I was also worried how it was going to fit. It wasn't nearly as bad as I had imagined. Yeah, thats the bad side about the RSK, you lose the plow mount if thats what you need to use.
Hi nice work. What is the measurements for the coil buckets. Thks
13" from the back of core support frame mount, to the leading edge of the coil bucket near the bottom of the frame. NOT the actual bottom of the frame.
Hi Garret, what are the measurements for using the oem 05 coil buckets? Thanks
I’d have to go back and measure. I believe I answered this in the comments section already. If you can’t find it. Let me know.
@@GarrettsOBSGarage found it! Thanks
In the process of the swap. Can you help me out with the ebrake and front brake line set up? I was able to use a adapter to connect the 05 rear line to the stock obs line. Is there something like that for the front lines or do I have to buy some custom lines?
I used a rear line as an intermediate line on this truck. You have to measure the distance you need and try to find a cable that works.
If the goal is a coil front suspension, why not just get a Solo Motorsports coil conversion or their coil over kit?
The goal isn’t coils. The goal is bigger brakes. Better turning radius. Better ride. Better tire wear. It also opens up the door for much better options in the aftermarket mass produced suspension components. You also end up getting a disk brake rear axle also doing the swap. The solo kit isn’t bad, but it’s not cheap and you’re still dealing with the Dana 50, and pivot brackets.
Is that injector knock? Mine sounds exactly the same, just has a little more clank to it
I hope not! haha. I haven't put any miles on this truck since I put the rebuilt engine in it, but this truck has bigger Rosewood injectors in it, however, its a 1995 block, so its a little louder than the 97 and later 7.3 engines. Plus, no insulation in the wheel wells to help contain the noise makes it even louder.
Hey could you show me how you put in your upper rear shock mounts? I’ve got my rear axle in and I’m flipping the drivers side shock the the front but my mounts don’t sit flush due to the frame how did you set yours? Also what are the specs for the steering gear box lines?
The shocks will have an angle to them, which is normal. The upper shock mounts don’t need modified or moved.
The video description has the steering box line information and how to modify them.
@@GarrettsOBSGarage Awesome thank you!
Are there any differences between the 05 through 07 steering boxes with the 2009 ones, and if so what information on that installation do you have?
The 2008+ boxes require modification of the intermediate steering shaft. You have to modify the rag joint to accept the different connection style.
can this be done on the 93 through 96 F-150 as well?
Short answer, yes. This can be done all the way back to the 1980 trucks, across the F-Series line up. With some minor differences of course when it comes to drive shaft adaptation, and possible steering adaptation.
Will the 05-10 SD transfer case work in these trucks? You used a 99-04 just wondering as i have a 07-08 f250 here would like to use the t case if itll work with the stock SD front driveshaft like you have
No, the input splines on the transfer case are different for the 05+ trucks.
See the video I made on the transfer case for more details on it.
ruclips.net/video/EikuTjfIwGY/видео.html
So what’s the parts list I’d need if I’m looking at a part out truck.
Basically, you’d want the rolling chassis, but if you’re looking at only parts from the chassis.
Coil buckets
Radius arm mounts
Steering box (if you choose). 05-07, 08+ is more difficult to use.
Then obviously your axles and attached parts like steering and track bar and wheels. If you choose to use sway bars, you’ll need those as well. The driveshafts are a plus to have so you can use flanges or the front shaft as a whole. If you want to do the transfer case swap, then you’d need that too.
It depends on how in depth you want to go, and also your skill set.
Where’d u buy the rear shock mounts?
The axle side came with the axle. The frame
Side came with the truck. 05-07 axles had bolt on shock mounts on the axle.
Whats the measurements for the coil buckets?
13" from the back of core support frame mount, to the leading edge of the coil bucket near the bottom of the frame. NOT the actual bottom of the frame.
That is a rolling scrapbook.
It sure is. Eventually it'll be a uniform color.
How would i go about this if i wanted to keep my truck lifted
Depends on your current lift and truck. A stock swap would net you about a stock OBS F350 height using an F350 rear block.
So, depending on your end goal, depends on what you buy.
@@GarrettsOBSGarage I may keep the rear as is now do the swap and I guess add a lift to the 05 front end when done
What truck do you have now. And how much lift?
@@GarrettsOBSGarage it's a 97 manual obs and I believe it has a 6 inch lift sitting on 37s
You’d need probably a 4” lift with a sky conversion kit if you went that route. You’ll need a different crossmember for the transmission as well since you’re. A ZF5. RYD makes that.
What yr coil buckets you using?
05-07
does it drive al that much better than the RSK ?
I haven't driven this truck much at all, since it's not anywhere near completely ready to go, but on the other truck I did this to, I've logged about 250,000 miles on that since the swap. An RSK with SD springs on OBS axles does not compare to the 05+ swap in terms of braking, steering, or handling. Even the 05+ swapped 1999 truck I did was a lot better. The owner said it drives like a brand new truck. He's had quite a few newer Fords, so he'd know.
@@GarrettsOBSGarage Sweet, thanks for the info. I am going to go ahead with the 05 option ! Your channel is a wealth of knowledge. Im almost through all the videos ..
I have done a lot of research but I still think I have two questions, if you have a second -
I am going to try to do this on the cheap, but that being said I still need custom parts such as the 05 compatible pitman arm and track bar mount. I think those are two things i cant get around (unless you have any suggestions). It says the track bar and pitman arm on RYD is set up for 0"-3" so i think that should work with the stock track bar ? I guess there is only one way to find out for sure..
Secondly is if you have ever done this with a zf-5 ? They say you need to buy a replacement cross member but its I would like to make my own or cut up the existing one, the $630 seems overpriced
Thanks !
I believe I have the pitman arm you need. I’d have to look in my stash of parts, but I want to say I bought one or two and then went to the SD box. I can look if you want me to and I’d sell it for less than what you’d pay for a new one.
As far as the track bar mount, the SKY one was probably the best bet back when I made this video, but as I hear it RYD has improved their process. The SKY one is setup to use the original track bar but only if you use their buckets which add 1” of lift. I used the RYD and I had a 0”-3” adjustable track bar on a 2” lift and I had to shorten my track bar for some reason with their track bar mount on OEM buckets.
So, if you use the OEM 05+ buckets, you’ll NEED an adjustable track bar for lowered applications unless you do at minimum a 1” lift on SKY. If you go more than 1”, you’ll need an adjustable track bar for a 0”-whatever (lifted). I don’t know what the RYD would need, and the best bet is to call and ask them.
I had a ZF truck here last week with the RYD crossmember in it. I didn’t install it, but the guy who did said it sucked to get all lined up, but it’s very engineered and looked decent and fit nice. You can try and build your own, but you have to completely move it out of its original position and have a way to make something structural to hold the transmission and also avoid other things like the driveshaft and exhaust. So, while the crossmember is a little pricey, it’s probably worth the money once you factor in the headache of trying to build your own and make sure you have proper height, and alignment, and clearance.
The issue is, the radius arm mounts occupy the same space as the ZF crossmember, so you have to move it to a totally different spot.
I appreciate the positive feedback also! I’m glad it can help you out!
@@GarrettsOBSGarage Definitely a lot of help, i really appreciate your videos, and your responses !
RYD claims the track bar mount works with 0-3" so i think i will try that, the BDD has adjustments built into the mount which may be handy. I think i will try to keep my costs down by avoiding buying a track bar
I think my best options are RYD or Blowing Diesel, They both have good reviews and are easier to import into Canada. They both claim to work with 0-3" lift so thats what im after.
I would be very interested in buying the pItman arm, name your price ! Is there a good way we can message ? or an email i can contact you at ?
What modal transfer case ?
It’s an NP 271
Will that work on a gas e4od. With a 1356 transfer case
It’s an NP271. Here is a link to a video covering the transfer case installed in the truck.
NP271 Transfer Case Swap into an OBS Ford
ruclips.net/video/EikuTjfIwGY/видео.html
Yes, you can use the NP271 where the 1356 was. Your shift linkage may be different in length than the one I used because my truck had a 4407, and the driveshaft will also need the specified front yoke to mate to the transfer case and the proper length as well.
RUclips wasn't showing me your comment until today for some reason, I apologize for the delay in responding.
There’s a company that makes a flat flange for the 4407 for 120 dollars
The 4407 in this truck needed rebuilt, and I paid 200 for a the 271. The 4407 is too hard to get parts for, and if you do find them, they are expensive. I looked around for flanges and what not, and I wasn't too happy with my findings, so I swapped it. Where did you find that flange?
High angle driveline made mine and funny thing in my area the 271s are hard to find I have 2 of them out of the 20 plus parts trucks I’ve got but I probably have 6 4407 tcase setting around
I’ve heard of HAD. But, never had dealings with them. They don’t advertise stuff like that though. You’d have to call and request it.
Me and another guy spent about 2 months trying to find an F350 4407. The F250 4407 is plentiful. If you find an OEM F350 yoke, you’ll pay out the nose for that, they sell locally for 150-200 when they show up. I’ve seen them for 250 online from used and new retailers. Then you’d need the F350 front shaft also, which is what I was going for. The DC front shaft. Couldn’t find a used one around anywhere, and a new one was 500 bucks. That’s why I recommend the 271. But if you can’t find one. Then you’re kinda stuck then.
The 350 yokes are a pain to find I got very luck and purchased a f350 parts truck for one of mine with a very good shape front shaft the 271 looks like a great swap I honestly never thought about it one of my personal extended cab long bed 4x4 truck 96 I 05 axle swapped it I ended up using the 2005 crew cab short bed 4x4 6.0 rear driveshafts right in place of mine except I had to get the 1410 to smaller tcase pilot hole for the 4407 tcase but lengths where perfect
That’s awesome you got the right length driveshaft like that. The SD shafts are usually a little off from the OBS ones. That’s why I suggest the 271 vs trying to find an F350 4407.
To answer your other question you asked. No
Lots of good info thanks man, What’s the measurements on those front buckets?
It’s in the comments section. I am not near the truck currently. Sorry.
