Making the driveshaft work - help?

Running a double CV driveshaft from an explorer (kevin correct me if I'm wrong on that), and on the axle end it used the external full circle snap rings on the u-joint. My D60 front yoke isn't the style that has the two cast-in pins that hold the u-joint in place, and I haven't been able to find one like that either. It uses the internal snaps. Ideas for that?

Also, the transfer case end (CV yoke) uses a different bolt size that the transfer case yoke. Is it best to drill and tap the transfer case yoke? Seems like this would compromise strength a fair amount, although the bolt sizes aren't too much off.
 
Anybody know where to get the 29 spline D60 yoke that just holds the u-joint in place with the two pins cast into the yoke?
 
Anybody know if I can get a 1310/1350 u-joint with external snaps on the 1310 (driveshaft yoke)? I can't find the type of 1310 yoke I need, but there are 1350 yokes that will work. I'd save a bit of money if anyone knew where I could find that particular 1310 yoke, or if anyone knows a company that makes them.
 
Not sure what your asking about the axle yoke. For some reason I was thinking the exploder front shaft was a 1310. I don't think you'll find a 1310 D60 yoke.
EDIT: Never mind, they do exist

Try here perhaps

I believe the yoke you need for the tcase (D300 right?) can found on
Cherokee Tcases
MID/Late 70s FSJ Quadratrac Tcases

It'll be a 26 spline CV yoke.

My favorite bone yard has a bunch of pulled tcases. I just dug through those till I found one that fit the drive shaft, and then pulled it. Compare it to your old yoke's splines and sealing surface.

Are you sure you want to run 1310s with all that?

There's also a conversion Ujoint from 1310 to 1350. Dunno how good an idea that'd be.
 
Thanks for the information on the 26 spline CV yoke. Any specific years for the cherokee t-case yoke? The reason I wanted to run CVs on this is because I have 3 1310 joints on each driveshaft, so I wanted to run them all the way around for the ease of carrying spares. I have seen the 1310 to 1350 conversion joints, but I believe that u-joints will probably break sooner than axle yokes will, and I don't believe that two 1350 caps on a 1310 body will make all that much difference.
 
Well

I just pulled yokes till I found what I needed.

You can buy them new for about $40

I think this is it. The splines could be correct, but then the
seal surface may be wrong.

The yokes from a Dana 20 have the same spline count, and will work with the Dana 300 <---I've done it. The bennies are you have 'u bolt' holding the u joint vs. the 'strap w/ bolts' holding the u joint. Just a thought.

I would strongly recommend you not run 1310 joints on a rear driveshaft.

Go bigger, 1350 at least.

Not necessarily. In fact not probably. Most D20s seem to be 10 spline. There some 26 spline D20s. They seem to be most common in 1979. All three 79 CJ dana 20s I have are 26 spline. Every other year has been 10 spline. I also doubt you'll find a 1310 CV yoke on a Dana 20.

Definitely while you're at it go bigger.
 
Rich, the rear driveshaft uses a 1310 u-joint. Would you use a 1310/1350 joint with a 1350 yoke or have the driveshaft re-yoked? The reason I bought used driveshafts was so that I could get out the cheap way... so much for that.

My rear Dana 70-1SU has a 1480 yoke. It's beef. For that reason I was really wanting to run it, but a 1480 yoke on a driveshaft that was designed for 1310s would end up being a joke under torque.
 
I wouldn't run 1310 anything on the rear shaft.

You're 100% on that 1480? those are gigantic... 1410 I could see..
 
I mic'd it at 1" 7/32nd, which isn't 1410 or 1480... but it wasn't a very accurate measurement. It's definitely a 1410 or 1480 because of the 4.188" width. I think I got the mic a little bit tight because 7/32nd is pretty close to 3/16th... which is the 1410 cap size (1.188"). What would you recommend? The double CV 1350 shaft from high angle driveline would be desireable... but I bought used driveshafts for a reason, remember.
 
Anybody know if there is a 1410 slip-yoke available for that small of a driveshaft? It definitely seems like a yoke with a 1410 end on it would be a joke.. but I'm looking for something that will work sooner than later, especially since the slip-yokes are around $60 and driveshafts are way more.
 
Oops

Life lesson learned. Since I used my '79 Dana 20, I Ass-u-me-d :confused: all were that way (26 spline), but a Dana 20 from a late 70's Wagoneer front CV? would that work? Later, T.J.
 
Yeah

If it's 26 spline, it should. Though I suspect it is 10 spline as I don't see that one mentioned as one to look for

The list usually includes
70s FSJ with quadratrac front yoke
XJ front yoke

I've pulled all my 1310 26 spline CV yokes off of cherokee tcases.
 
Thanks to Kevin I was able to find the 1310 yoke I needed for my front 60, and I will probably change the 1410 rear to a 1350 CV yoke so that I can run a 1310/1350 u-joint on it. Also, I've pulled my t-case yokes and will be going to Marsh's on monday to get some XJ t-case front yokes. Just to make sure, the 231s are 26 spline?
 
I run 1310's on a heavy 78 Bronco with 460, 38" boggers, and fully locked. I've busted two ring gears and about a dozen axles shafts, but never lost a driveshaft ujoint on the trail.
 
almost

XJ or
I got one of off a Dakota as well.

I also pulled one off of a Durango that was close. 26 Spline and all, but the back shaft part of it was too short, and when tightened down on the output shaft, the dust cover hit. I even had a spacer in it, but still...

I think the one you're looking for has a 15364 cast into it (something close to that too lazy to go look).
 
Got two 26 spline NP231 CV yokes today, and have changed the front and rear to 1310 yokes. Driveshafts squared away - thanks everybody for your help. Things like the NP231 CV yoke I never would have known or found out.
