When I installed this axle housing I set aside the axle assemblies and installed my 2007 axle assemblies. I did this purely because I knew the maintenance record of my axles/bearings. Fast forward to earlier this summer and I was feeling like the 2007 bearings were starting to make noise and...

I'm on deck to rebuild the rear hubs/axle assemblies that came with my 8.2" axle housing. They've been collecting dust at the garage and now one of my current bearings is complaining. I threw a code for interference with wheel speed sensor and inspected it last weekend. Something (dust cover?)...
Dropped the new chunk in last night. 3 hours from wheels up to wheels down. Everything went smooth and gears sound fine. I'm taking it easy the next couple weeks to break the gears in properly. I've got a 14 mile commute to and from work on surface streets, running stop & go in the 35-45 mph...
So my gears never really set up like I wanted and I did the setup myself. There not showing abnormal wear and gear mesh looks fine, backlash is holding within spec, just noisy as crap. And I've been nervous not having a spare on the shelf - most sources say they are 2-4 weeks out on 8.2" turn...
The only difference between the pre-2010 and 2010+ axles is a slightly larger (like 1mm) diameter on the outer hub. In fact you can almost put an older rotor on it, but it only seats about 1/4" before you realize there is a clearance issue. Why Toyota decided to do this is frustrating. The...

Technically no, because I used my former axle shaft assemblies. But when I do use the axle shafts that came with it (and I will, once I've rebuilt the hub bearings), I will have to install the slightly different rotors from a 2010+ FJC.
I didn't use the new axles right away because I...
As far as updates go... I've had some gear noise over the past couple weeks. I crawled under the truck a couple weekends ago and some of my nuts had backed off around the third member. Not falling off, but not still torqued, which surprised the hell out of me. I've only daily-ed it the the past...
I recall 2010 & up with e-locker will work. The car-parts site will search for interchange parts as well. So if you plug in 2010 FJC rear axle for the search, it will also search for compatible 4R too.
From a junkyard, less than $2K delivered. I think I was $1850 out the door. First axle I found was listed for only $1650 (but unavailable). You might get lucky. I used www.car-part.com to search.
For the time and effort, I would just find a junkyard 8.2" like I did. I honestly feel the 8" rear axle was adapted from the mini-truck platform and never engineered properly for the weight of our trucks.
Got back to the garage last night to strip down the old axle of all usable spares. Here's a closeup of the axle flanges on a 8.2" axle. Note the extra lip where the rotor seats (especially rusty in this case).
Also tried to see if the old housing looked noticeably bent. It does not, to the...
Never needed more reach than 4.56 gives me with 34-35" tires. Does reasonably well at highway speeds cross country. 4.88s would be better on the trails no doubt, but this is still my daily driver.
More pics of the installation.
New gears installed last weekend.
New chunky 3rd is a lot thicker at the mounting surface.
New housing looks to be a bit thicker at this area too.
After carefully disconnecting everything, I left the linkage, wiring harness and the brake system plumbed...
Finally got the 8.2" rear axle in place. I kept my brakes and wheel sensor harness. Chunky 3rd got rebuilt last weekend with 4.56 gears.
Fun fact, the axle shafts are identical except for the bore diameter where the rotors seat on the hub flange. They made a lip on the flange just about 1-2mm...
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...
