Rear diff swap

Hi there,
So I bought a 1997 CCLB 7.3 f350 with a blown rear diff. I have a spare 10.25 axle to swap the diff from. Has anyone done this before? Any advice/steps? Thank you

Blown how?

Is the axle from a 92+? You need the VSS.

If it’s 4x4 you’ll want the gear ratios to be the same front and rear

Are you swapping thr whole axle or just the carrier? If just doing the carrier I'd get a master rebuild kit when you do it so it comes with new bearings and seals. I'm building a 10.35 right now and got a motive gear kit with Timken bearings. It was about 200 from Summit.
