My truck now is a 4x4. If I put in a unit from a 2wd and change the adapter plate on the rear so it will bolt to the transfer case, does the output shaft have to be changed, or will it be long enough?

Transtar's catalog show's different part #'s for 2wd and 4wd output shaft. Not sure what the difference is.

I did the same thing on mine. The output shafts are different.

I looked in my ATSG Allison book and it look's like the 4wd has external thread's up past the slip yoke splines for the jam nut and the 2wd has internal thread's on the end to bolt the yoke on.

4WD shaft has different splines than 2WD, also takes a spanner nut against the output bearing. 4WD spacer is different, no teeth (tone wheel) like the 2WD. Ususally the spacer shim thickness works out differently as well to set end play.

Ok, I went and picked up the truck... They did change the output shaft- I got the bill. Thanks for all the help- case closed.
