How long can I drive in snow with part time 4x4?

[gptoy96]

Damn... well i happen to be in the wrong here, my bad. It still sounds stupid to me, but you're all right.

It must be an american thing... but i just asked about 10 guys here at work, and they all agreed with my definition.... weird.

I like the Canadian defintion better

Dont speak for all of us Canadians with your definition, lol. :cheers:

In my area of Canada we're familiar with part time is shiftable and only for limited use with slippery conditions and full time is for anytime (as long as center diff isn't locked).

I'm in Eastern Canada and use the same terminology as you (the correct terminology)

It's not a Canadian thing.

That's good, cause it would be bad if the "Canadian thing" is "being wrong".

That being said I also found out that part time 4x4 is not as good as full time 4x4 in the snow as it can change your vehicle dynamics. (locked wheels cause side slip)

Well, the part time is better for some cases if the full time doesn't have any lockers.

Correct me if I'm wrong here, but with center open diff, and both axles open, if you had one wheel off the ground, the diffs would allow it to spin, taking power from the other 3 wheels, whereas with part time, you would have to have 2 wheels off the ground to lose power on all the wheels.

Okay, i will call it a Newfoundland thing then. I don't know why, but i asked about 20 guys at work to define "part-time" 4wd, and they came up with the same answer as mine.

Having a different definition from yours does not make me wrong. :rockthrow:

 

[theizzardking]

you can drive in 4x4 any mode

(FOR-EV-ER)
as long as you are on the right surface for the traction setting in 4x4.

please read the faq on what the different types of 4x4 are for in the sticky section above this thread.

:lookout:

it does if your definition is incorrect

 

[mistaj0hnny]

Low range is for when you want to crawl along at low speed for better control, or need some extra mechanical advantage compared to high range. You probably would never need low-range on any paved roads.

With your '01; When you push the button on the transfer case shifter you will then be in full-time 4wd, high range. You can drive like that on any surface, for as long as you want. Because the differential in the transfer case will allow the front and rear driveshafts to turn at different speeds, so you won't have any binding in the driveline.

If you are in this mode and then press the switch on the dash to the left of the steering column that looks like a diagram of a front and rear axle, with an X in between the two, this will lock the differential in the transfer case. You will then effectively be in part-time 4wd, and should try to use that setting only when the roads are slick. Pushing this button to lock the diff in the T-case, can improve traction in slick conditions compared to just having the 4Runner in the full-time 4wd setting.

Thank you!! Great info.

2 pages and no pictures of the hot chick cmon now

Really?..... we are still arguing this.....lol.... I don't get it.... its not a debate, part time and full time are industry terms used in legalese to describe products . But honestly I actually agree with the other guys as the notion of full time 4 wheel drive sounds like the front an back are locked together full time...... and part times could be understood as only working together part time..... lol. Now I'm just starting stuff lol

Maybe thinking of it like this will clear things up:

Part-time 4WD = normal 2hi, 4hi, and 4lo (standard 4x4)
Full-time 4WD = AWD

All '96-00 4x4 SR5 models and all 5-speed 4Runners are "part-time 4WD", meaning you can either use 2WD or 4WD.

'99-00 Limited models and all '01-02 4x4 4Runners can be considered "full OR part-time 4WD", meaning that they are "part-time 4WD" in all circumstances except when in 4x4 with the center diff unlocked. Then they are in AWD mode a.k.a. "full-time 4WD". These models with the multi-mode system can be considered both part-time and full-time 4WD - unlike an Audi which doesn't have 2wd, it is always AWD a.k.a. full-time 4WD.

brian-
didn't you take like 30 mins-1 hour to put together a comprehensive list of the modes and descriptions of the 4x4 systems in our 4runners and put it in the sticky up top? Seems like alot of work that could help others....where would something like that be anways......

hhhhrrrrmmmmmm FAQ maybe.........arguments like this are stupid, just read....

i do see the confusion though, the op shouldn't be so pig headed though and just go with the flow, it's all just terminology anyways.

Yeah I made the "T-Case Differences" thread, but it's not a sticky yet. I think only mods can make it a sticky but it would be nice if they did because this question does come up a lot.

I didn't go into the part-time/full-time explainations on that thread because it is just gets too confusing especially since the '01s and '02s are sort of a hybrid part-time and full-time together. It was easier to avoid that terminology altogether and just use the terms "standard 4x4" or "multi-mode".

Well shoot, if you put a front locker on a 99 limited, you would have "everything"-time 4WD/AWD... or something like that...

so since i m a rookie can i drive it on highway with 4wd hi on my 98 runner when snow is on the ground? i mean the highway isnt 100% straight

You shouldn't exceed 50 mph in 4x4 with your t-case, but if there's snow on the highway, I wouldn't think you'd be going over 50 anyways (I wouldn't be). On a dry road, you want to keep cornering to a minumum in 4x4, but if there's snow on the road, you can drive in 4x4 and not worry about the curves. Often where I live, the road is just wet with maybe 5-10% covered in ice patches and in that case I still leave it in 4HI the whole time. And as long as the road is even just wet, it's fine to just keep it in 4x4. There's a little room for slippage built into the system. In these kinds of conditions, the AWD feature of the later model 3rd gens puts even less stress on the t-case and allows you to drive much faster in 4x4 (even on dry roads). But for the rest of us that don't have multi-mode, keeping it in 4HI isn't going to damage anything unless you're really turning tight corners on dry surfaces.

Go to fridge, take out nice cold can of soda, open, pour in lap.:flamethrwoer2:

simple rule of thumb to check things out is
put it in 4wd in a parking lot and try to take sharp turns going very very slowly less then 2-3 miles and hour, if it starts to hop,chop,bind or act funny then no you can't drive it on pavement, like ever, you need to have loss of traction possible at any moment.


if you do these turns and it handles normally and only feels a little heavier then normal, then you should be fine on pavement , patchy ice and pavement or pretty much anytime.

doing this little test should tell you regardless of what sticker you got on your shifter.......

otherwise read this thread over again and read this thread

I don't get why people say you can't drive '96-98 on dry pavement in 4wd. You can. I do it quite often. As long as you aren't turning you won't have a problem. I've had mine in 4wd up to about 80 MPH, maybe more.
