ScottyC, first off nice find. Definitely looking forward to the finished product 
You mentioned that your new 2000 4Runner has 4.56 gears stock...have you verified that by lifting up the rear of the vehicle and counting the turns of the drivershaft and rear tire? I only ask b/c I've never heard of a '00 V6 auto (w/elocker) come stock w/ 4.56 gears? Someone correct me if I'm wrong, but didn't the majority of elocked thirds (if not all) matched with the V6, come w/ 4.30 gears only?
I have seen 4Runners w/ 4cyl engines have 4.56 gears stock, but I've never seen newer 3rd gen V6 autos w/ 4.56 gears...elocked or not. I think if Toyota offered 4.56 gears on V6 4Runners, you'd see more guys swapping out their 4.10 third members for 4.56 third members down at the local swap meets. I know I would!
And 5.29s w/ an auto on the highway...don't know if I'd do that, but that's just me. I'm sure when you're pulling a loaded trailer behind you it'd be ok, but I'm curious to hear how your 4Runner will do going down the interstate @ 70mph without a trailer...seems like the engine would be screaming.

I am basing it on the axle code on the VIN tag. Axle code is 04 which is 4.56s. I can also verify it with an RPM calculator and its spot on.
You must have missed my previous post about the stupid tall OD in the A/Ts. The KM2s measure out at 33.3" tall tire and 5.29s is perfect for the A/Ts. I will still be turning less RPMs at the same speed than a manual truck with 4.56s and 33s.
At 70mph on the freeway with 33" tire and 5.29s and the A/T = 2639rpms
At 70mph on the freeway with 33" tire and 4.56s and the M/T = 2763rpms

I did read that about the OD. I agree, it IS crazy tall. I just hear more guys going w/ 4.88s & 35s on a daily driver V6 auto 3rd gen, than I do 5.29s & 35s on the same vehicle. Nonetheless, when you get the new gears, I look forward to hearing how the 5.29s and the new 33.3s handle at freeway speeds. Definitely keep us posted.
Oh and a word of caution - I have heard of axle codes being incorrect in 3rd gens. Owner opens his 3rd member to install a locker and while he's there, he checks to see what gear ratio he has only to find the gear code on the vehicle does not match the actual gear installed.
Granted, you'll know exactly what gear ratio you have once you tear into the 3rd member...I simply want to make sure you know what you have before you tear into it. Elocked 3rd gens are hard enough to find in good shape as is...add 4.56s to that rarity and I say you struck gold.
Funny you're stepping up to 5.29s...I'd kill just for a set of 4.56s.
they sold 4.56's with the auto and an e-locker. I think that was after they dropped the 5 speed and the 4 cylinder. Quick way to get more "power" so you can keep up with the competition without a major revision. They did this on the previous gen as well with the introduction of the 4.88's towards the end of the generation.
That's awesome. I had no idea.

FWIW, when you compare 4.30s vs. 4.56s there is such a subtle difference that its not worth the time to swap them. I am very confident that I have the 4.56s. All of the RPM calculator readings tell me they are 4.56s. My GPS also tells me that my speedo is spot on, so based on everything I see its definitely 4.56s.
5.29s would actually be perfect with 32s with the A/T. Even then, it still leaves you with lower than M/T rpms at cruising speeds. And remember, the M/T gets better mileage running at a higher RPM than the A/T does.
Every Toyota motor built from 1979-2004 is more efficient running at 3000+ rpms than it is at 2500 rpms. The 3.4L is no exception. They designed the power band and torque curve to work better and more efficiently at higher rpms.
I have no doubt that 5.29s are the way to go if you don't want your A/T to constantly hunt for 3rd gear.

No factory 4.56's in a V6 3rd gen. If it's an auto V6 e-locker it could be 4.10 or 4.30, most likely 4.30. 4.30's were part of a package with 16" wheels and the bigger front brakes.
The auto's get better mileage than the 5spds-I've had both. My 5spd with 4.88's and 33's turned more rpms than the auto's with 4.88's and 33's. But with gears and bigger tires, gas mpg is gonna suck either way. My 5spd with 4.88's and 33's would pull the heck out of a 3800 pound popup camper and 3 people in the 4runner with it loaded down too-it would pull all that at any speed you wanted to go.
My current '96 project has 35's, auto, and 4.30 gears and it's fine, 4.88's would be better, but it's not worth the $$ to regear it in my opinion for what I'm using it for.

I PROMISE you they made 4.56 lockers. www.car-part.com, search 4Runners for differentials, you can select that option and then proceed to buy one. I came within a few days of buying one on there for my 90, but decided I needed the money for something else.

No problem, only options on a V6 3rd gen were 3.909, 4.10, and 4.30-4.30 was most common on e-locked limited's (but an option on SR5's) and only available with the auto, best you could do with a manual was 4.10-all with the V6. With the 2.7 you could get a 4.56 on special order.
E-lockers on a V6 only came with 4.10 or 4.30. The only way to get a factory 4.56 e-locker was with the 2.7 and I believe only with the 5spd-not positive about the 5spd part though.

But it honestly doesn't mean much to me since I will be going 5.29s anyway.

Not sure on all the other comments made prior to this, but if you have 4.56s they should work fine on my 99 4runner 3.4 auto???

4Runner, couldn't get one in a 3.4 4Runner.

So, I went to the CO 4runner Jambo this weekend. I sponsor this event every year, so I always try to attend.
I took the boys out and we spent a great five days in Buena Vista. We did a lot of fishing and ran Tin Cup Pass all the way over to Taylor Reservoir and then back over Cottonwood Pass. Most of the weekend we were by ourselves just exploring the easier trails in the new 4runner.
