Trans axle texh?

skipnrocks · Jan 9, 2018

So I'm running a Buick 3.8 and am at the point to break the trans axle down to get my custom outputs made. But I look at this thing and am not sure where to start and can't find good data online. Does the whole thing need removed?

why do you need to break down the trans? are you not making outputs from old CV shaft stubs?

I was going to send my spiders off and have some Chromoly shafts made. I don't think itt will Ben much more to do it that way than to pay for the lathe work to
Make oem shafts work. Plus I wasnted to mess around and see if I could fit a full or mini spool in there to get my shaft size up.

Can you see straight thru the diff? Would you Be able to make a one piece shaft that goes all the way thru to engage both sides then attach yokes on each end?

I had debaoted that. I haven't looked but I assumed there would be a cross pin in there. Also I worried about a yoke that would bolt to it

It looks pretty easy to weld up the spiders on that configuration from what I've seen on the net. Getting shafts/yokes to work will be the challenge. which transmission do you have?
I'd keep it simple to start with then if it breaks make it better. I don't think you would break at the cv cup/spline.

Then get a buddy or shop to machine your cv cups to accept a weld yoke and walla
Kindof like I did. This pic is from a honda setup, but same concept as yours I think.

Edit....I forget about the pullout issue lol

i just put a light coil spring on driveshaft pushing out and have never had it pull out transmission on my recent buggy

That was the pic I was looking for I just decided to tear into it this am and got that far. I'll weld the spiders in the am and put it back together. I'm going to see if I can get a spare set of shafts since we are going to Ben in Moab a week and want spares

I like that idea. I'm going to do the same I need to find a driveshaft yoke that will mate we'll with my output shafts and go get the large work done.
