200 series part time kit ? (1 Viewer)

[cruiseroutfit]

Manual hubs would be tough with the current unibearing front hub setup, i.e. Lacking a true spindle. With the 80/100 kits were/are easy as they utilized nearly the same parts or at least style as factory hub equipped applications. Hubs could be done but the cost is going to be a great deal more than the 80/100 variants.

@bjowett you got those hubs made yet?

I've always wanted tundra gas mileage!

FWIW- I lived with an ‘07 4Runner V6 for 12yrs. It could 2wd, 4wd (High or Low, semi-open Torsen or locked center diff). Because it was an OE application instead of hubs it incorporated an axle disconnect to reduce front axle drag while in 2wd. It was a good car and that system was my favorite feature of that vehicle (roll down back window was cool too).

The downside of the 4Runner system is the switch from 2wd to 4wd could occasionally get glitchy. If you understood the sequence of events you could help it with technique but you had to understand it. Translated when I loaned the vehicle especially if inclement weather was forecast I’d leave it 4hi and tell the borrower to leave it that way.

Bottomline is it was about 1.5mpg better in 2wd. Do I wish my LX could have the 4Runner t-case? Sure, it’d be nice but I’d spend only a small amount to get there. IMHO there’s better places to spend money. Truth is I’d run my 4Runner in 4high a lot. It tracked better, felt more stable and generally nicer. A 12.5gl aux tank, some skids, a secnd set of tires, @bhicks BH3D cupholder or ____________ are all better places to spend money IMHO.

My correspondence to Marks4WD in Australia.......

Guys, is there any plan to make a 200 series part time kit?





Hello Bill

Thank you for your email,

We are still looking at options, but as it sits I don’t think it is going to be possible
We will keep trying

Bump. It’s almost been a year. Has anyone heard anything new. I’m coming from a 100. And this was the mod I’ve ever done.

I believe @ToyotaIsLife has done this mod.

If someone were so inclined...

The Tundra shares an almost identical front differential carrier to our 200-series. They have an Automatic Disconnecting Differential (ADD), which is functionally equivalent to automatic disconnecting hubs. Everthing including the CVs, diffs, and prop shaft will still be driven so mileage savings would be minor, but it will disconnect positive drive to the front wheels. On the Tundra, the transfer case also decouples the front drive shaft to save parasitic draw.

I didn't bother to try myself, but it's been said the subframe on the 200-series won't clear the ADD mechanism. Could be done if one were motivated enough.

The ADD mechanism is the thing in the middle of the Tundra carrier that doesn't exist on the 200-series.

 

[Cruisin911]

On my tundra, I was never impressed by the ADD system (nor on any of my 4runners(previous generation was vacuum operated and tremendously finicky or tacomas that had the same fork mechanism). The ADD system needed monthly exercise to be reliable, same as the 200. In my opinion, the demand simply isn't there to go what I consider is backwards in capability. With the above stated ~1.5mpg difference to add the ability to disconnect the front doesn't close on the cost for me. Yes, you could hoon the tundra a bit more but it was tremendously less capable for the use case on the 200 product line.

You can modify a 200 to be 2wd by modifying the transfer case. Quite commonly done here in the GCC mainly for drifting/ acceleration and slight mpg/ tire wear gains. You switch back to 4wd by engaging the center diff. 4lo still works of course as center diff is locked.

I can't see this being terribly difficult... I pioneered the AWD swap in the Tundra... this should be the opposite of that swap. No axle gear changes required. The lack of front harness for the diff disconnect could be overcome by developing manual hubs. Or the 4WD ECU could be swapped, the harness possibly run. Another chap in Canada took the swap a step further and installed a Sequoia multi mod case... which required the ECU swap.

Would you mind sharing the link to a tundra awd conversion?

What about hubs?

Good info!

Tundra AWD swaps.

Project traction

Let's face it, the Tundra has an issue with getting the power down to the terra. It's really no surprise with the power it has stock, never mind the supercharger (which is really the catalyst for me to find something as I'll be installing te TRD SC in the coming weeks). As most know, traction...

AWD conversion completed

I guess this could go into the driveline section, but to me it is definitely a performance mod. Those of you with supercharged trucks and those with stock trucks in cold/snowy climates know how hard it is to get any traction in 2WD on take-off. I have an S/C truck in Canada, so I find that most...

No idea what they were saying, but the 4.6 uncorked sounded pretty amazing.

I’m still confused how he’s not using hubs? How does that work?

You can be 2WD (front drive of t-case not engaged) with or without hubs. Without hubs your front CV's/diff & driveline are still spinning, just not powered by the t-case so it's not optimal IMO.

Ahhh that makes sense. That kinda seem to defeat the purpose tho to me. If they did that. Wouldn’t there still torque steer?

No, that torque steer comes from the front being driven under power. That would go away but it would still be running the parts.

As mentioned earlier, you would be disengaging the drive from the t-case, so no power to the front driveline.
I've seen a few videos with free wheel hubs installed.. but note that disconnecting only the free wheel hubs on the 200 it will not move forward on drive unless the center is locked

That was the one thing about the 4runner TRD I had a few of them all had manual 4x4 selector . I seen a few guys on couple of Trundra forums doing the LC 200 transfer case swap .
I accept the LC 200 for what it is , I can only re invent the wheel so much , would like a LC 200 with manual trans / manual 4x4 and Diesel but not building that again , I did the Suburban you see in my profile picture had all that and more , selling than paid a good chunk of my 200 LC when I moved east .
