I recently ate another set of gears in my '07, and they were only a few months old. Decided that the axle housing is cursed (or more likely bent) and it was time for an upgrade. Researched some of the more popular options: 8.2" out of a newer FJC/4R, Nitro/Diamond 9.5" and Currie Rock Jock. Went through several options of how to rebuild the diff with a locker, if I had to use a non locking axle assembly. I ended up talking to Nitro and East Coast Gear to analyze cost with all options. Decided the best option for me was the 8.2" because it was the most affordable, kept things mostly unchanged as far as OEM parts and because it was the most affordable
So I went on a hunting expedition for a junkyard axle that wasn't on the other side of the world. Harder than you think. I found a 2012 4R axle that actually turned out to NOT be the right thing. He told me it was an e-locker axle, but he misinterpreted the VIN decoder that said it had a center diff lock (ie 50/50 tcase in 4Lo). Found 2012 FJC axle in Grover, NC and had it delivered. They didn't know much at all about the truck and the pictures looked like the truck had rolled, so it was not my top pick, but it was the only pick available right now.
