I'm looking to run a trans and xfer case that looks to need a front shaft which will need a carrier bearing. Although I've been doing my investigating as to which bearing or how to run it I am still confused as to which one to actually get, or how to mount it. This will be on a flat fender running yj,s spring under with toyota axles. Any help will be greatly appreciated.

When I had the SM420 transmission in my fun fender I made a 2pc shaft using a carrier bearing for a GM 2wd truck and an old front output shaft from a D20. It worked fine all the time I had it in the vehicle.

As long as you have hubs in the front I don't think you have to worry about angles on the joints too much.





My only suggestion is to try and make sure you can get the carrier bearing out easily with whatever bracket you design. Mine was a pain in the rear for packaging so I had to mount it half stupid. I like having a normal front driveshaft if possible but it was nice not really having to worry about smacking the front driveshaft on much of anything....

that wood depend on how big you need the bracket also when you build a 2 peice front becuse ov the offset you have to un phase the driveline its kinda hard to explane what you do is look at the h1 hummer they have 2 peice front youll see what om talking about pm me

I ran mine for 2 seasons and it was still fine when I pulled it. I think I used the $10 Autozone version too....

With the front drive system being part time I wouldn't worry too much about getting all the angles perfect. Make sure nothing is binding since the front shaft ends up getting pretty short.

I run a 3 piece shaft. I used a carrier from Wide Open Designs. So essentially I have 2 complete front shafts.

I like the set up and it works flawlessly. No vibes at speed. For my set up - very positive.

So negatives - you need some room to run it. My rig is stretched pretty heavily up front. So I have room. If you are stockish, I'd recommend following Miser's advice and set up. If you are stretched out, I'm a real fan of the true 3 piece deal.

id realy like to see how this turns out im a driveline tech with 20yrs behind me and unless youre a rock crawling . then a 1 peice should work just fine in fact if you have angle issues then pm me i make a 85 degree angle driveshaft for the most extreme

Wow, 85 degrees? I'd love to see a photo of that! :)

try using 1 2/4 .240 wall its stronger than hell and dosent take up much room
I had 1.25" diameter front shaft material, still not enough room.

It HAD to be a 2pc unit for the setup I was running. 2pc stuff is pretty common on this board with a lot of the buggy type stuff. Packaging is always fun....

please keep the bickering via pms. Im really hoping to find as many 2 or 3 piece shafts for a front shaft. Mieser, yours looks like the best bet. I have an 85 toy with the 2 piece rear shaft and it looks flimsy as all heck, though it would work just find for the front shaft. I'm glad Mieser posted a pic of the space available as I am glad there is just enough to fit the bearing.
