are there any differences between the axle shafts in a 9" from a 2wd and a 4wd truck? I am searching yards for axles and I found a couple of 9" from 77 F-150's but they are only 2wd, are they still 31 spline? If they are only 28 spline can they be changed to 35 or 40 spline?

Any F 9" can be changed to 35 / 40 spl.
This is because you need a completely different (big bearing) center cection.
The 'stock' 3rd member will not accept 35 / 40 spline carriers, unless you go with a small bearing 35 spline spool.

I want to leave the 31 spline, if thats what it has, in for a while until I can pony up the cash to jump up to the 40 spline shafts. When I go to the 40's I have to change the 3rd? I thought the carrier was the only thing that needed to be changed, that puts a damper on things just a bit.
