Codycobra84 Posted February 24, 2009 Share Posted February 24, 2009 By the time I get done I'm gonna know everything about doing these swaps, lol. Anyways, I know that when you swap a AX-15 in place of the BA-Crap you have to either A:have a drive shaft made or B: get one from the same wheelbase MJ that had the AX-15 already in it. My question is will my choice C work? Choice C being: swap the drive shaft end from the BA end to the AX-15 end (and by end I'm meaning from the u-joint forward to the tailshaft). Sorry can't remember proper terms for it. Basicly I'd keep my tube and everything back to the rear end but just swaping the actual part that mates to the tailshaft and rejoining it with a new u-joint. My question.....will it work? :???: Ant the other thing, no I'm not going to 4wd on the truck, I'm stickin with the 2wd for now. I just don't want to worry about the truck all the time thinkin the tranny is gonna just fall out of it. -Cody Link to comment Share on other sites More sharing options...
bigd44889 Posted February 24, 2009 Share Posted February 24, 2009 if length is same and u joints are the same it should work if i'm wrong i ill be corected :cheers: Link to comment Share on other sites More sharing options...

If that's what you mean, yes, it will work, and it's what I did when I lifted the truck. These can be found on Ebay HERE and you can saw it off at the length you need.

Codycobra84 Posted February 24, 2009 Author Share Posted February 24, 2009 I'm swapping the BA/10 to a AX-15 and don't wanna deal with having to get a custom drive shaft so I figured just change the slip yoke from the BA/10 21 spline to the AX-15 23 spline. -Cody Link to comment Share on other sites More sharing options...

AFAIK both yokes use the 1310 u-joints, so as long as the overall driveshaft length is the correct w. the 23-spline yoke it should work fine.

Eagle Posted February 25, 2009 Share Posted February 25, 2009 I think we're having a discussion at cross purposes here. 21-spline vs. 23-spline refers to the interface between the transfer case and the transmission, not to the transmission output shaft. The issue requiring a different drive shaft is length, not spline count. Link to comment Share on other sites More sharing options...

The issue requiring a different drive shaft is length, not spline count. So are you saying that a stock drive shaft that's behind a 2wd BA-10/5 will slide out of that tailshaft and slide right into a 2wd AX-15 tailshaft? I was told that lenghts were the same but the ends were different.....I'm gettin more and more confused, it would be so much easier if the tranny was sittin in the garage right now, lol.

Codycobra84 Posted February 25, 2009 Author Share Posted February 25, 2009 So....umm....does anyone know if that's right? I just wanna know if the driveshaft (tailshaft end) will work in both trannys. If I can figure that out, I'll get the length stuff figured out when the tranny gets here and ready to go in. -Cody Link to comment Share on other sites More sharing options...

So just another little tid-bit of info that I found out. So it's back to lookin for parts for me again. -Cody Link to comment Share on other sites More sharing options...
Eagle Posted March 4, 2009 Share Posted March 4, 2009 What didn't work? Are the splines on the output shaft different, or is the driveshaft length wrong? I was of the opinion that the same front yoke would fit all trannies and/or transfer cases. Link to comment Share on other sites More sharing options...

I thought they were just a swap in deal too, not having to mess with anything but pilot bearing, and mount.. hummmm... I have an AX15 sitting here ready to swap.... Cody keep this thread alive..

Codycobra84 Posted March 4, 2009 Author Share Posted March 4, 2009 Yeah the slip yoke in the factory BA-10/5 will not work in the AX-15 so now I'm on the look out for one from an AX-15. Trust me when this thing is all said and done and the tranny is in the truck I'll have a whole write up. I was joking with a friend of mine about the fact that when I get it done I'm gonna start making a swap kit with all the little stuff you've gotta have for the swap, lol. -Cody Link to comment Share on other sites More sharing options...

Spline count, length, what? The biggest issue was the size, the tail shaft comming out of the AX15 is a bigger diameter than the BA. The driveshaft yoke wouldn't slip over the tailshaft of the AX15 at all. So Spline count/length doesn't really matter b/c it won't slip over. Just another little bit of info to add to the list of things that don't work. :typing: -Cody Link to comment Share on other sites More sharing options...

Can you count the # of splines on the AX15 tailshaft? Then we can find you the correct slip yoke. :cheers: Link to comment Share on other sites More sharing options...

HOrnbrod Posted March 5, 2009 Share Posted March 5, 2009 Okay, then you will have to swap out the slip yoke for a 27 spline yoke, like this one HERE. This yoke is longer than the stock yoke, so you can cut it off to the correct length if the driveshaft needs to be longer than it is now. Link to comment Share on other sites More sharing options...

HOrnbrod Posted March 6, 2009 Share Posted March 6, 2009 Should be. Both the longer yoke and your driveshaft use the Dana 1310 ujoints, so you'll have to get a new ujoint to change the yoke. You never said (or I might have missed it) if your original driveshaft is too short or too long since you swapped trannys. Which is it? In any event though, you'll still need a new 27-spline yoke for your new tailshaft. Link to comment Share on other sites More sharing options...

I got my clutch in today, so now all I need is the Shifter/shift tower and the yoke and it'll be time to try again. :clapping: Thanks for all the help :cheers: -Cody Link to comment Share on other sites More sharing options...
