New 4runner...

I made the assumption that he's only considering 4wd trucks. The V8's are full time 4wd, while the V6 can select 2wd or 4wd. Of course, either is available in a 2wd only model.jonhul said:
Youre right, new 07's will be hard to find at this point. The invoice on a 4wd SR5 V8 with basic options (mats, 17" wheels, roof rack, spoiler) is right around $30k. I dont know what the rebate is in his area (mine is only $500), but he should be able to get a new truck for under $30k very easily (before TTL, of course).snhrph said:

Of course you meant to say that all V8's equipped with 4wd are full-time 4wd.
Because you can buy a V8 without any 4wd at all.

Not really. The V6 "part-time" system can be left in 4wd permanently if the driver wants to use it that way. Therefore, I would say that the V6 system can be described as either a part-time or full-time system, depending upon how the driver wants to use it. Some guys with V6 4Runners leave their vehicles in 4wd always, so I wouldn't say that there system is part-time 4wd if that's the way they decide to use it.
The only real difference between the V6 and V8 systems is that the V6 system has the option of disengaging the 4wd. But if V6 owners choose not to disengage their 4wd, then they are really using it as a full-time system.
Either way, it doesn't really matter as long as it is clear that the systems are identical other than the fact that the V6 allows the option of switching out of 4wd.
The owner turning the knob doesn't change what the system is. At least I don't think so. The system is what it is regardless of what we want to do with it, but I understand what you mean.
Ok, doing a little reading up on the subject I guess because of the Torsen system there are basically 3 types of 4wd systems now. Whereas in the past their were only the two, up until Torsen. I'm not including AWD of course.
Part Time: 4x2 or 4x4 no center diff.
Full Time: 4x4 center diff.
Mulit Mode: 4x2 or 4x4 center diff. (Torsen)
To the best of my knowledge Torsen is the only maker or a center diff. "multi mode" system.
Sorry if I've taken this off topic.

True, but the owner of a V6 4Runner pretty much determines how it is used. So if Joe Blow buys a V6 4wd and NEVER takes it out of 4wd, then I wouldn't exactly say his 4Runner is part-time 4wd. He's using it as a full-time 4wd, so that description fits better, IMO. Just because he has the option of using it 2wd doesn't necessarily make it a part-time system if he doesn't use it that way.
Here are a couple of links to some information. It's consistent with everything I've read about it. To my surprise there isn't much out there that discusses a part time system with a locking center differential.
This is how Toyota describes it.

This is one of the many, but the most consice I've seen in describing it. However his "IMPORTANT" note is not taking into consideration the Torsen center differential in our trucks which I've found to be the case in a lot of descriptions of part time 4wd.

It is my understanding that the part-time/full-time titles refer to when you can use the system:
Full-Time: 4WD that can be used all (full) the time.
Part-Time: 4WD that should only be used part of the time, when on loose/uneven/snowy roads.
I don't think it refers to whether someone can switch into a 2WD mode. It's still a full-time system.
For example, my old F150 was a part time 4WD truck. I only switched into 4WD when I hit bad roads.
My 4Runner is a full-time system. I switch into 4WD two days before its forecasted to snow and forget about it.
Anyone?

well there are lots of opinions here that disagree with the "expert" advice saying never drive a part time 4WD system on dry pavement which contradicts one of the previous posts.....I think that Toyota made the 4WD on the V8 somewhat different in that it would never be a PT system. just my opinion but makes sense.......

That's because a typical "part-time" 4wd system isn't supposed to be driven on dry pavement. That's why I keep saying that the so called "part-time" 4wd system on the 4Runner isn't really a part-time 4wd system.
It's more of a full-time 4wd system that can be switched to 2wd. The reason I say that it because it can be driven in 4wd all year long if so desired. The V8 models have to be driven that way, and the V6 models can be driven that way.

IIRC, Thai has a post in one of the sub forums.
AWD: no low range gearing, has a center differential which allows all the wheels to receive power and turn at different speeds. Unibody Toyota SUVs are AWD.
4WD: it has low range gearing, all Toyota trucks and (truck based) SUVs that are 4x4 are 4WD, some are part-time while others are full-time.
Full-time 4WD: has low range gearing and a center differential, which allows it be driven with power to all the wheels to receive power and turn at different speeds. Locking the center differential in makes it behave like a part-time 4WD vehicle because all four wheels rotate at the same speed.
Part-time 4WD: has low range gearing and no center differential, all four wheels recieve power, but cannot turn at different speeds. Thus part-time 4WD drive systems should not be operated on dry pavement, since it'll cause excessive and unneccessary wear on the driveline and/or tires.
TORSEN: stands for TORque SENsing. Both V6 and V8 4WD 4Runners have this. TORSEN center differential is what allows the 4Runner to split it's power upto 71% to the rear and 53% to the front under slippage conditions with a normal 40/60 front/rear split under normal conditions.
With that said, the 4th gen V6 4WD 4Runner in 4H is no different than the V8 4WD. I stick by my statement that the 4th gen V6 4WD 4Runner is a full-time 4WD with the option of 2WD.
