Does anyone know if the rear axles from the 2005 and 2011 are substantially different? The 2011s come with an e-locker and they cost about as much as buying a locker for the earlier axle.

The 2005 has the VSS in the differential, the 2011 has the VSS in the trans IIRC .

I've been reading a lot since I posted and it looks like the issue is that it has a speed sensor at each wheel for the stability control. Not really possible to deal work that without a ton of work. Now I'm wondering if there's much of any difference between the 06-07 and the 08-10 axles.

Hypothetically speaking you should be able to use one of the wheel speed sensors in place of the older style VSS that set on top of the diff . It may require some recalibration, or it may work just fine, but it accomplishes the same thing, the rear spring perches are the same from 99 thru 2011, that I know because I am putting a 2011 rear and front in my 2K SD .

The rear switched to a flange instead of a yoke at some point, not sure what year, but the 2011 has a flanged pinion .

Assuming it's the same kind of signal, I suppose that could work. Let me know how it goes for you.

Do you have to reinforce the frame?

Can someone expand on this- “old leaf springs that clunk”. I noticed on my 4wd F350, wheels turned hard, backing up, I would get that “clunk” - is this a normal characteristic of the front leaf springs? I was unsure of the noise. Thanks!

Sounds like mine. But I don't know enough about it to know whether or not that is a normal characteristic.
