The GX case has a lever for Hi and Low, but relies on an electronic actuator (activated via dash switch) to lock the center diff. It's easier to fix when it leaks, but you still have that electronic component.

The only thing I'd really add is that the FJ T-Case doesn't have the T3 Torsen center diff in it like the 4th gen units IIRC, so you might get a bit more binding out of the front end. The ADD (and the addition of the T3 Torsen in some of Toyota's T-Cases) was meant to reduce the binding you'd experience in 2WD and 4WD modes.

But honestly, if you've driven an FJ or a 5th gen non-limited 4Runner in 4Hi then you'll get a good idea of how it drives.

As for the leaking transfer case actuator, it's a bit of a hassle to replace (did I ever document rebuilding my transfer case? I can't remember it's been years :S ); but they usually don't leak that badly. The large majority of 4WD issues I see are in the following order; lack of regular use (seriously guys just run it through 4WD once every month or two for about a 100ft or so, saves so much trouble...), failed/failing position/detent switches, dipshits managing to lock up their transfer case in 4Lo doing dumb shit.

Interesting swap, I've thought about throwing the GX470 T-Case in my V8 for the fun shift lever; but sorta decided my money was better spent else where.

Post Note-

I will point out that the older 4WD systems are rather simple and don't have that many inputs/outputs to the rest of the vehicle, but the ABS system may not be super thrilled with you when you're playing with it in 4Hi/4Lo in certain terrains (mainly because the switch outputs do feed into the ABS to sort of "detune" the aggressiveness of the ABS/VSC/TRAC functions; though in my personal experience it'll still fight you off-roading in some cases. So wire up a kill switch to "disable" the ABS/TRAC/VSC systems, the easiest way is to hijack the signal from a wheel speed sensor (the driver's rear wheel goes through the junction connectors at the driver's kick panel" and just hook it to a switch. When you kill a speed sensor it'll throw the system into a deep failure mode and shut down a lot of it's functions (I had mixed luck with unplugging the master cylinder sensor on my own rig when the system was fighting me, I know it works for some people, your mileage may vary and all that.)

One more note, the majority of the reason the electronic units start to shift slow/stick has more to do from lack of regular use; the grease that lubricates the gears starts to clump around the teeth; it's basically a lot of gear reductions to get the shafts to move. Lack of use lets the grease thicken around the teeth (even worse during cold weather, 90% of the 4WD issues I see are because the system was never used since the previous winter and now that it's snowing outside they can't get it to move and the grease is gunky and thick) and the motor struggles to get the gears going. Hence why I mentioned you should exercise the 4WD and Center Diff lock somewhat regularly. You'd be surprised how many times I've used a deadblow to "unstick" the actuator and then just cycled it a dozen or so times and she shifts like brand new. lol

Thanks for sharing your knowledge! Yeah I'm not sure how the ABS and traction control will react, but my VSC TRAC and VSC OFF lights have been on for years now so I think I haven't had traction control in a while anyways. I'm not 100% sure why my electronic actuator crapped out cause I abuse the 4WD and center diff lock at least once a month on some heavy wheeling trips. But at this point I don't care, it gave me a reason to put the FJ case in

Fair warning don't be surprised if I PM you with some questions in the future! Still trying to learn more about all the weird Toyota electronics.

I've not experienced any binding in either 2WD or 4WD with the FJ case and the AWD front axle.

Day 1 Update

So little update after today. No where close to being done. I’m learning that most people have done this with the V8 that has the longer 5-speed transmission. Since I have the 4-speed, everything is farther forward and everything is in the way. Lots of cutting and tough decisions. Spent 4 hours just getting the shifter positioned how I want. I’ll post pics tomorrow, hoping to get it done tomorrow as well.

So two things.

First, it does seem like the FJ Cruisers with 6spd Manual Transfer Cases did come with the T3 Torsen in them (which makes sense now that I think about it since they were All-Time 4WD, my apologies.)

Second, the binding occurs in 4WD on turns most noticeable close to lock. The reason for this is because the drivetrain can't slip internally so it binds up a bit when turning. This is part of the reason why the ADD system exists and why the T3 Torsen was put in the All-Time 4WD transfer cases, between disconnecting the front differential internally to allow the left and right axles to spin independently of the ring gear assembly, and the T3 Torsen allowing something like about 20% slippage front to rear this provides enough slip in the drivetrain that you don't notice any binding on turns in 4hi.

If you've ever driven an old domestic truck in 4WD or a newer non-limited 5th Gen in 4Hi on dry pavement while doing a tight turn you'll feel what I am talking about in regards to the slight binding, not a super big deal; but a bit annoying.

OK, I see what you are getting at now.

Yes, the manual 6 speed FJ case has the center differential, much the same as the 4th gen AWD transfer case found in the V8s, which is what I replace. However, the manual 6 speed FJ transfer case will not work for this swap, so don't even bother thinking about it. Different input shafts that are not interchangeable.

All 4WD systems have some binding when driven in 4WD. This is not the same as an AWD system, which generally have some sort of center differential system to allow for slip and prevent the binding that you are talking about when driven on pavement.

True 4WD systems are not generally designed to be driven on pavement for lengths of time. You can notice binding driving in 4HI on pavement but as you said, it's usually only when you have the wheels cranked to almost lock. Offroad, you will almost never notice binding because dirt/sand/mud/snow will allow for wheel slip, therefore preventing the binding. This is not a concern as the systems are designed to work this way.

Now here's the thing. ADD doesn't prevent the binding you are talking about when you are in 4wd. ADD ONLY disconnects one of the axles from the differential, the passenger side in Toyota's case, to allow the front differential to basically free wheel and prevent the binding. This only happens in 2WD. If you are in 4WD, you essentially have the same front axle that my previously AWD 4Runner has. Not as strong but they work the same way. ADD doesn't just randomly unlock and then lock again if there is binding present.

Oh man, didn't think about the 4 speed auto being a little shorter than the 5 speed. Don't later year V6 4runners have the 5 speed? I thought the 4 behind the V6 was limited to like 2003/4 and maybe some of 2005?

All V8 4runners have the 5 speed, fortunately for us.

Looking forward to the updates, really interested to see the different challenges with it.

Yeah, I was more pointing out that you'll experience some binding in 4Hi without the benefit of the T3. You'd be surprised how many 5th gen owners we've had who swapped from a 4th gen and were like, "it binds up in 4Hi on turns, my old 4Runner never did that!" I will point out that Toyota's All-Time 4WD is not entirely the same as their AWD set-up, as it is a true 4WD set-up; as opposed to AWD in other Toyotas where they'll use electromagnetic couplers on the rear diffs to disengage the rear axle input shafts similar in concept to the ADD to allow slip and disengage/engage AWD as the vehicle sees fit.

You're right about the ADD, my point about bringing it up was in explaining how Toyota reduces the binding issue and also making anyone who does the swap aware that they may experience a bit of binding on tight turns in 4Hi after swapping in a non-T3 transfer case. I wonder how many people remember the days of manual hubs and such.

I hadn't thought of that as well now that you mention it. Should be 2005+ V6 4Runners got the A750F, 2003-2004 V6 had the A340. All the V8's had the A750, with the 2003 model being an oddball and using only ATF T-IV (not that it matters in this context.)

I also wonder how critical it is to have the spacer machined round vs. purchasing a slice of round stock? Anyways, I'll go back into my hole now and stop leaking unnecessary information everywhere.

I also wonder how critical it is to have the spacer machined round vs. purchasing a slice of round stock? Anyways, I'll go back into my hole now and stop leaking unnecessary information everywhere.
Yeah I have the 2004 V6 so I have the A340F that is shorter. And what are you referring to with the spacer? You mean the rear driveshaft spacer? I'd assume it requires machining to keep it relatively balanced. Also, it needs to have pretty tight tolerances to match the driveshaft flange bolt pattern as well as the centering ring to line it up to the transfer case flange.

The reason I was musing about it was because of how much it could throw it off balance. It's one of those things they drill into you when you wrench that you should always match mark the shafts because it'll throw them off balance when you reinstall them. Though honestly I've only ever heard it be an issue if you do that when replacing universals vs. bolting the shaft itself back on.

Yeah it didn't really throw anything off balance. I'll be able to make my large update posts later tonight with pictures, but the spacer doesn't mess with the driveshaft balancing at all and I didn't have to separate the halves of the driveshaft at all. Drove it all over town and up to 70 and everything was just fine.

Good to hear. I was concerned with the spacer. Personally, I went with custom fit driveshafts, front and rear. Had them made at a local driveshaft shop and they did a great job. Ran around $600 for both, so not exactly cheap. Whole project was still right under a grand tho. Cheaper than trying to fix the stock tcase IMO. And more reliable.
