Rear axle swap

[w666ninja]

I found a video online that outlines the swap from the weak 8.6 10 bolt to a semifloating 14 bolt from a 88-98 heavy half, and had one found but the truck disappeared. So my question is this: has anyone tried to fit an axle from a 2011 half ton in place of the weak 8.6? It's going into a 2002 yukon with the coil spring suspension so I'll be replacing spring perches more than likely I'm wondering about width. I have one such rear-end in my possession with only 40,000 miles on it. 373 posi. Same ratio I need. I hope it's not an 8.6 too.... Please help!

A few members have put a NNBS 14bolt 9.5" ring gear Semi Floating axle (aka AXN named after the rpo code) into their NBS 00-06 SUVs. Me included and the swap is fairly simple. Here is a thread that outlines more about it, if you skip to last last page or 2 I break down the different options you will have.

9.5SF Swap

So I'm not supposed to be planning any more Tahoe upgrades but here I am. Found a 2014 Escalade 9.5 SF 14bolt with 152k on it for just over $400 shipped to me with a year warranty. From the research I've done it should be nearly a direct swap besides either a U joint adapter or shortening the...
