F350 to F250 axle swap
#31
My driveshaft won't work, I got two shafts from the guy I got the diffs from. One looks just like the stock 250 shaft, the other one has what looks like a CV joint, both are at least 2 inches shorter. The stock 250 shaft would hit on the cross member if it dropped much.
Which one should I use and if it's the one with the CV joint I assume that goes to the Transfer case, it has 4 bolts instead of ubolts.

I "thought I read somewhere" that the Manual Trans requires the longer shaft and the Autos are a bit shorter. Which do you have again?
Mine is an auto and it bolted right in. I did pull mine out a bit though. No issues with cross member or anything.

Well the solid axle swap is a success except I now have a really good looking 2 wheel drive. I've drawn a blank trying to fit a front shaft. The f250 shaft is too long, and has about 1/4 inch clearence from the cross member trans mount. I know I can get the shaft shortened but would have to cutt completely through the crossmember and drop a section a couple of inches. If anybody has hit this same wall and could throw me some ideas on where to go from here it would be much appreciated.

Need a Track Bar Bracket
I'm starting a Dana 60 swap for my 97 F-250. Just bought the Dana 60 today from a guy who was scrapping his old truck. I requested the track bar bracket, but by the time I got there, the truck was already on its way to the metal yard with the bracket still firmly attached. Does anyone have a stock bracket for sale? Know where I can get one? Thanks

Well after 2 months of busted knuckles and head scratching my solid axle swap and rear diff swap is done!!!!
I'd like to thank everybody on here that helped in this process.
Some advice to anyone that is gonna try this, make sure you get all the F350 parts, and if your truck has a 1345 transfer case you may want to get the F350 1356. There doesn't appear to be a yoke that will mate a cardian joint to a 1345. I shortened the f250 front driveshaft about an inch it works fine but I have the expected high speed vibration when in 4 wheel drive.
I dropped the transmission crossmember to under the frame rails to provide shaft clearence. With a spacer under the transmission mount and spacers on either side I have about an inch of clearence for the front shaft.
It's been a fun project and thanks again for the help, and if anyone has a solution to the
high speen vibration caused by the front shaft, let me know.

Axle swap, pros and cons
Since you have had time to drive your vehicle with the F350 axle swap, can you shead some light on the benifits and maybe the negatives ? Did it change the ride? Softer or firmer, is it more noticable when you hit a pothole? How about high speed handling, does the truck roll more since it is raised up? Any other comments?

FWIW, if you used the 250 springs up front that caused the rough ride. They are stiffer than the 350 springs. I tried to follow the thread but can't tell exactly what you ended up with. The vibes may (most probably) have been imbalance in the front shaft or improper pinion angle. If a pro did it, I would not go back to that shop again (If you were sure you got tho pinion straight). It should have been balanced after cutting/welding. It would also vibrate if is was not perfectly straight.
And for any future searchers/readers, for a TTB D50 to D60 Monotube swap off a 350 you need from the F350:
Track Bar
Track bar bracket
Steering tierods and Draglink
Springs
Drivers side spring plate
You may also need to shorten your F250 front drive shaft.
