V8 AWD to Part-Time Conversion?!

[Good Times]

i highly doubt it's the torque due to the motor since the tundra and the sequoia is both part time v8.

bulldog is right that the part time system does have the ADD so thus you'll need to change out the front accordingly. having the ADD also means that you can't lift it as high as the ADD will act up and start to have problems like the previous gen 4runners (3rd gen) where they were limited to 2.5-3" of lift.

you're best just getting the v8 and call it a day bias opinion but i love mine to death and I'm sure others will agree.

good luck

Does a V6 4WD have less lift potential than a V8 4WD? I always thought a part-time system would be less hassle with a lift. Sounds like a a full-time system may be better... but I not sure why.

V6 and V8 have the same lift potential

Search through the forums. I'm pretty sure there are V6's that are lifted just as high as the V8's.

Toyota made 2 models for the 4Runner (aside from options). V6 was for the way most people drive (drive to work, to the mall, to the store, with the occasionaly jaunt into the mountains or to the beach). V8 was intended for luxury and the appeal of the extra horses/torque. All manufactures target the average driver and their intended demographic market. Toyota makes the 4runner to appeal to 20-somethings and 30-somethings, with the LandCruiser and the Lexus pulling up the 40-somethings and 50-somethings (this coming from a marketing manager at Toyota).

Even though you may be off-roading in this, for most people this is also a daily driver. I loved my CJ7 off road, on road it sucked. The 4Runner I love both on and off road (and I have the V6).

Get the engine you would be happy with 365 days of the year.

Great answers soon

The great thing about the new Tacoma is it will bring massive aftermarket to our vehicles, having the same driveline and all that ours does.

The very reason I chose the v6 was purely because of selectibility, now as for being able to do the swap to part time on the v8, I'm sure it won't be a problem, someone will pioneer it soon, but it won't be me.

I'm sure, thanks to the Tacoma, we will have so many people interested in our 4wd systems soon yo uwill not be able to handle it. Example: downey, Marlin, spidertrax, fabtech, pro-crap, rancho, etc... They all support us now, but they sell so many more products to the taco's. It will be very soon that we will all be happy

Re: V6 and V8 have the same lift potential

I wouldn't exactly say both versions can get the same amount of lift. If you look back at the previous gen 4runners, the ADD system was the biggest challenge. Since the v8 doesn't have the add system I would suspect that the v8's would have the upper edge on being able to get abit more.

Then again, with the stock geometry I would never want to go beyond 3" regardless of which model you have.

Regardless, back to the thread, you can't go wrong with either 4runner. The reason is because it's a 4runner Get what you want and what you can afford and be happy. Almost everyone (1 in 1 million? hehe) love their 4runner (v6/v8, sr5/sport/limited) you name it they love it. Just look forward to driving a vehicle thats the best in it's class and even better than some others in other classes woo hoo!

First off our 4runners are not awd. It's a fulltime 4wd system. Remember that an awd system does not have the 4LO feature. This seems to be a common mistake by alot of people since they know it's a full time system. awd systems are found on volvo's, subaru's etc etc. We get that extra 4lo for the umph that the others don't have! hehe


I thought our trucks had AWD, they just called it full time 4wd. I had a full time 4WD in my pathfinder. The difference is the pathfinder did not have the ability to utilize the ABS to transfer power from the "wheels that slip to the wheels that grip" hence making it all wheel drive. It only had the center differential keeping the front and rear drivelines from binding like on part time 4wd systems? I wonder if the difference is in the center diff itself? It will not fully lock up if need be?

 

[Good Times]

this thread should clear up the facts of awd vs 4wd.

I see that Good Times beat me to posting the link to that thread. Also be sure to look at the link that Faeylyn posts there.

One comment, while the common definition is that adding a transfer case with Lo range gear makes an AWD into full-time 4WD; still there are different types of AWD and full-time 4wd systems. In addition to the basic components of full-time 4WD the 4Runner system upgrades the center differential to a lockable, Torsen Limited Slip differential. Also, where some full-time 4WD systems use viscous or hydraulically actuated couplings to handle loss of torque due to wheel slip, the 4Runner system, in addition to the lockable, limited slip Torsen center diff, also uses the components of the anti-lock braking system to handle individual wheel slip; Toyota calls this TRAC or ATRAC while Mercedes-Benz calls it ETS.

Awesome reading. Clears a lot up for me except one thing. In 4WD Hi, we can lock the center diff true, but if you don't? If you don't shit into 4 LO? The link explains that some systems use a center diff lock, some use some other form of spin control other than diff lock, ours has both. I just thought since our 4runners will try to use each wheel individually as needed, it is indeed trying to drive all wheels.

Here is a link I was reading.

 

[J_W_Speed]

I meant SHIFT in the last post sorry; another link http://www.thecarguy.com/articles/drivesys.htm there tells that 4WD and AWD are not the same because all wheel drive can direct power to a single wheel. Our trucks can do that! So again, I am confused as always. Gawd I suck at posting.

 

[dcampen]

Different people use the term AWD to mean different things. You really have to ignore the overly broad labels and look at the specific functionality of each system.

Another term that is misused is when Limited Slip differentials are called Locking Differentials. You will even see people talking about the "lockup ratio" of the LSD. This is misleading as just LSD functionality doesn't mean that the differential can be locked. In the case of the 4WD 4Runners though, the center LSD can also truly be locked.


Toyota, in their 2005 4Runner brochure, muddies the water even more in describing the 2WD models as having an "Auto limited-slip differential" when really what they are describing is the ATRAC functionality.

The AWD and Part-time 4WD systems are IDENTICAL (i.e. same transfer case, same axles, same sensors, same transmission...). The only difference is that the AWD is on all the time.

I was thinking that the 2WD-4WD switch used on the V6s could be installed on the V8s allowing multi-mode.

I have a 2wd that I converted to 4WD using all Toyota parts, I can say 100% using the multi mode switch does nothing. I have teh V6 switch and it operates in 4HI when 2wd is slected and in 4LO in both other modes.

Secondly, the V6 has an extra shift fork in the T-case, I am unclear if changing the shift rail/Accuator will give you 2wd mode or not, but I do know that the switch alone is not the cure.

when someone is ready to send me a spare V8 Tcase to take appart I will solve this once and for all, Fact is, someone has to try this to see if it works. I was Able to convert a Lexus to 4WD with little effort, and I was told it could not be done. I happen to know that on the AW6 Transmissions from Toyota and Lexus, a NP231 T-Case is a very easy swap. You wont find that in any manual, you have to be willing to try it.

Sorry for the rant, today is a slow day at work.

Its possible to swap, to do it right this is what you need to do:

4RUNNER FJ T CASE SWAP | Toyota Off Road | Anaheim | RockSolidToys

 

[rdruss]

If you want to see how the AWD 4runner tcase works go to weberauto on youtube and watch the video on the CD transfer case under Toyota, it's very good.

Yes I am resurrecting a very old thread. I have a 2003 T4R Limited with V8. I am swapping transfer cases as mine in cracked and leaking at the actuator. I went to www.cart-parts.com and found an INTERCHANGEABLE transfer case from a 2018 T4R with a V6. Everything on the exterior looks exactly the same. I am confused why it is marked interchangeable yet it probably will only work in 4LO or 4HI. We will see once I get it installed. Cheers.

Subscribed. I'm interested to see your results.

Help On Buying tips?

Hey guys I am new here. Currently in the market to get a 4Runner but I am wanting a V8 4WD. I am concerned about the mileage on all the ones that I am finding for sale and the price range. I was just wanting to see if someone could help lead me into the right direction on what a fair price would be and opinions on the reliability. I am wanting something that will last me at least another 100k miles but most all the ones I find have 200k + mileage.

Whatever advice anyone has would be much appreciated!!

Thank you!!

 

[ryanking61]

Picked up an FJ Transfer Case from an automatic FJ. My electronic tcase crapped out and I'd rather have manual shifting. I've seen alot of people swap this case in for the V8 instead of getting a part-time case from a V6 4Runner.

nice work!
