Front driveshaft

[Mike7009]

I have a 90 wag with soa/sf running ford f250 axles. My front shaft sets at about a 21 degree angle at ride height. I currently have a shortened xj shaft ( not balanced) that I've done some clearancing on the double cardan joint.. in stock form the angle was maxed out at ride height. It now starts binding at about 28 degrees. My suspension at full droop I need to be at about 33 degree angle. So I need a shaft that can handle that. Currently stock np229 front yoke and I have a 1310/1330 conversion joint at the front axle. What driveshaft shops are good do deal with? I have an email in at Tom woods. They said they may or may not be able to help. So I'm waiting on another reply from them.. What are my options? What is everyone else doing for front shafts with this much lift?

I take it you have a low pinion axle?

Won't help you but I used a high pinion spring over and since I was using a Dana 300 I had to have the punkin moved. Spent a lot of time figgering how much to point the pinion up so the joint at the pinion is at zero and the CV joint at the TC takes what little angle there is

Yes it's a low pinion 8 lug 44 from a 78 f250. Ive thought about swapping for a high pinion but it just seems like alot more work then just getting a shaft. If you or anyone knows some other good driveline shops other than Tom woods that I can contact that would be great.. But I know theirs alot of people who have gone soa. So their has to be a solution for my issue

I thought '78 had high. Mine's from a mid to late 70's F250, can't remember exactly what year.

Can't help on a source. I wish I were to the point where I needed drive shafts.

Maybe look for ads in the back of a 4WD magazine.

There is someone on here from Las Vegas, actually Pahrump I belive that owns a driveshaft shop and is very knowledgeable with fsj. I wish I could remember his handle. Hopefully he'll chime in

1350s

I used all 1350s in my soa low pinion drivshaft

I was thinking I may have to go that route. I've also considered just trying to do away with the double cardan joint and just use single joints at each end. But the angles would be all out of wack. The double cardan setup is more ideal. My front axle uses a 1330 joint so I'm using a 1310/1330 conversion joint currently on the xj shaft I have in there now

Axles came with the jeep. I was told 78. All the parts ive gotten i bought for a 78 and they fit. But it's definitely a low pinion.

double cardan

Well, I'm the guy from Pahrump.....There are some high angle cvs' out there but typically mated to a later model flanged front yoke.....That and the normal ones are are 1410 u joint..

Probable the greatest issue besides price would be your front yoke.
I have successfully converted my NP208 over to 1330 w/ 1330 on my Dana 44 and this will work good for me. Actually running 1330 cv's front and back.

What are the chances that you know or would find out exactly what your xfer case yokes' measurements are? spline count, spline diameter, and seal surface diameter.

I converted my Dodge 3500 from AAM1355 joints and built a normal 1350 shaft. That being said, even w/ say 4-6in lift on those trucks will hammer a 1330 size cv in time.

another option is to clock the transfer case down to gain better angles. you are about maxed out with what you have, i am surprised you have not blown apart the shaft yet. i have spent a ton of money on making the front shaft work for high speed desert racing and the best i could get was around 26 degrees and survive. you may find it better and cheaper to change the front axle out of clocking the transfer case in the end.

I ran conversion joints for a while and I think the joint is probably a large contributor. IIRC the degree of travel is greatly reduced when running the conversion joints. You are running the SOA/shackle flip... are the front springs reversed long side to the back? this moves the front axle forward a good 5" and helps with angles a LOT. was a necessity when I did my np435/205. I used a cut down XJ shaft too.

Bronco Graveyard has several different yoke options and joint configurations. I sourced a lot of stuff from them for my Waggy.
I'm not 100% anymore because this was a long time ago... I wanna say the 205 and 229 yokes can be modded to fit each other?

Tom Woods shafts are tight. I have them front and back in my CJ-7.
