COMPLETE Coil Spring AXLE SWAP in My 2002 F-350 7.3 

Leroy Routt Thank you!

Nicholas Tashjian You said it my friend! Not at all

This is the comment I came here for. Buying one this week and don't want to have to get the whole frame piece too

@@Legend-fw6eb yeah man. Look around on Ford forums, like Powerstroke Nation, or The Diesel Stop. Those dudes can tell you more about how to do it. But it basically involves getting the front axle, and all the suspension linkages. Everything should bolt right up, except for the 04 steering pitman arm, to the 05 drag linkage. The 05 steering system uses bigger ball joints, so you’ll need to ream out the 04 pitman arm to fit the 05 drag link. You’ll also want an 05 rear axle, as well. Reason being the lug nuts are different, the brakes are bigger, and the track width is wider on the 05. So you’ll want both axles to match. Hope this helps, go to Powerstroke Nation forums if you wanna look more into it. Good luck on your build!

@@LimaTangoZulu awesome man great useful info, didn't know that about the pitman arm and drag linkage. I already have an 08 rear end, so this is the icing on that cake to finish the ride quality to how I want it. Read a couple of forums but that's one part I haven't seen. Getting everything needed except that subframe for $500, some cleaning painting and new hardware and hopefully it comes out nice in the next couple months.

@@LimaTangoZulu doing this all on an 01 7.3 also so not sure if that made much difference from the 99-01 I know a few things changed as well

@@Legend-fw6eb now a 2008 you will have to fight it a little more to make it work. I would go with a 05-07 axle to make it easier on yourself. Nobody would be the wiser lmao.

Ditch the radius arm and leafs and coil swap it

John Smith Thank you! I actually got it in PA

Gerald Fiorello Thank you very much

Craig Hunter I would have, but it would’ve been a 5 day video if I showed every little step along the way lol. That’s why I shortened it to steps since I think it’s doable with what I said and to watch without gettin too bored! What questions do you have I can answer them.

@@Jimmyziggy I have a question. I have an 01 f250 7.3 4x4 long bed crew. My truck got hit and the frame is bent and a bit rusty. Can I do a full frame swap to a 2005? Or is there differences in the back half of the frame as well?

Thank you. It’s a lot to do it this way. A lot of people just pull the axle and swap it with the bed one and mount the coil buckets and radius arms which is fine too i be heard. I just felt safer pulling the cab and changing the front section for the reinforced frame from the later year.

Only the 05-07 will be an exact match as far as I can tell.

Beagler Bass Fishing & Outdoors I know that, a lot of people have questioned me on it. In the video i explain why: the frames are different from 05-07. Much beefier to support all the weight of the coil spring on the cross member. Old frames cracked during testing so Ford updated it. Sure people have gotten away with just swapping the brackets but I don’t like taking chances going against the way the 4wd coil setup was designed with the frame. I know all the holes are there and everything, but that’s for the 2wd version, a much less rated version of suspension than the newer 4wd axle.

King Shaka Customs i dont think the weight is much difference.. leaf springs prob weigh more then buckets and springs or about close.

Beagler Bass Fishing & Outdoors Beagler Bass Fishing & Outdoors I’m not disagreeing with you there. My point is that the leaf spring contacts in two spots on the frame, whereas the coil spring makes contact at one. The force distribution is a lot different therefore. Hence why they supported it more where the coilspring makes contact. One day I can make a video more explaining my thoughts and calculations

I did a an axel swap on my truck I have an 04 f250 4 wheel drive haven’t had any problems

The issue isn't the weight. The leaf's put the load force straight up into the frame while the spring buckets try and twist the frame towards the engine. This force is s why spring tower supports are put onto vehicles like rally cars.

Bilco Construction I’m not sure yet

What do you think of the Swap Helper Cluster kit? It's $600 but takes minutes to install and uses all the functions. Unfortunately it also takes another $500 to make all the functions of the column work.

Brandon Wetklow Honesty I’m not sure, But if you do all the work your better off putting the upgraded coil axle under it

they also have the same lug pattern 8x170

G Gg Haha of course i can. The framing and structure was getting redone so the rails and stuff weren’t in place. if it was that easy i would’ve just done it

@@Jimmyziggy lol. That makes sense. I was thinking what the heck. Haha. Good stuff sir

G Gg Thanks!

Matt Smith Because if you look at the 2wd components, they are much less rated than the 4wd version from 2005+. And it also takes into account the nature of a 4wd truck versus a 2wd truck. People are more likely to off-road in a 4wd truck which adds more force and impact as you can imagine. Do many people do it? No, but it gets factored in. Also think about plowing, the extra weight of a plow on a 4wd vehicle, that cause more stress on the front end. People don’t plow in 2wd vehicles (well most people don’t in these trucks at least). The frames were fine for the 2wd coil springs, up until testing and analysis were performed on the 4wd version of the coil springs and estimated loads and occurrences with it. It’s also about material fatigue and internal deformation of the material over time too. I can go on further, but I will make a video explaining it all one day eventually. I’m not trying to scare anyone here who’s thinking or has done an axle swap, I’m just looking at it from an engineering standpoint, because that’s what I am - I have studied and dealt with the ways material failures could occur similar to situations like this.

The reason more so being that the 2wd SD’s use TIB still with two points of contact (pivots) vs a live axle front axle. To be honest with you I don’t believe it was a huge issue either way. I believe the engine crossmember gussets came about with many changes from Ford trying to stiffen the frames of the 05+ trucks up over the 99-04. If I recall correctly they also changed the frame thickness in the change over as well.

Yea I did but i'm glad i did. I could've done it to just drop the axle, but i was doing some engine work at the same time, and i got to paint the frame, and honestly to re-graft the frame to me was more worth it than to punch out the coil bucket rivets, and to drill the three holes up front in the cross member, and to adapt the other components. In the end the steering gear box and everything was already in place ready to go and meant to be on this frame, so I didnt mind it.

@@Jimmyziggy yea i was that, good work man. I’m doing this swap right now.

What did you do about the ABS sensors?

And that gram cracking thing I’m not too sure about that. What about the 2wD models? We’re the cracking?

Yes they did

Yes it is

@@Jimmyziggy ok so I’m confused by doing this does it mean I can put a newer trucks suspension?

Camera quality was not good in this video

Haha no that’s a very poor camera and poor lighting
