4WD

[pinkfloyd4ever]

I guess I'll apply this to my 01 Durango, but have always had a fun sort of debate with my friends on this. How should you engage the vehicle into 4WD. I've always thought that had to be at a stop or very slow. I got a friend who says that you can engage it into 4WD basically at anytime.

I have always just pushed the button or pulled the leaver whenever I felt I might need it. Im sure it is probly "better" to slow down but I have never worried about it. Ive always thought as long as all the wheels are going the same speed (not spinning the rears and stoped fronts) it is ok.

As long as the wheels arent spinning it shouldnt hurt anything, but I think the manual says under 50 mph

Whatever the manual says. I can shift the Toyota in and out up until 60mph. After that it just blinks until I slow down under 60 and then try it again.

Mine blinks and beeps Also beeps at me when I get a little squirelly around corners

(can't believe I wasted post #3500 on that)

Just out of habbit formed from older trucks I have own (I mean old), I always try to do it at a stop. But like said above, most push button and switched AWS systems can go into 4h at pretty much anything under 60. Now, 4 low is another story

Airjer, can you shut your VSC off in 2WD or only in 4WD? Mine is always on in 2WD.

Thanks guys, that gives me piece of mind, I've always just thought engaging the system at a higher rate of speed would just cause a massive cluster and better to do engage the parts at lower speed.

Also I had looked in the manual and didn't find any rule or what have you on engaging it, just the simple turn the know to 4H or 4L

I would make very sure that if you do go into 4low that your going less that 10mph. 5mph would be even better. It really gears down.

[Scott K]

I would be stopped if you want to shift into low!

Here's the 4LO instructions for my truck -

Shifting In or Out of 4LO

Notice: Shifting the transfer case into 4LO while

moving at speeds faster than 3 mph (5 km/k)

may cause premature wear to the transfer case, and

may cause the gears to grind. To avoid causing

premature wear, and grinding the gears, do not shift

the transfer case into 4LO while the vehicle is

moving faster than 3 mph (5 km/k).

I've only used it a couple of times, and I've either been stopped or rolling very slowly.

[deadeye]

There you go! I knew your were supposed to be going really slow. I always stop with mine but I thought I remember that you could be rolling very slow.

[Shack]

With my Expedition, I have to put it in Neu. for it to shift into 4L . I pretty much have to be stopped. I have never tried (or will ) shifting into Neu. while rolling and then shifting/flipping the switch into 4L.

I wonder if that would work Nope, not going to try

[Ralph Wiggum]

Wuss.

[Shack]

Hey now!

If I have to I will

[Dozer]

On my chevy it will go into 4lo under 5mph. I sounds horrid when it does it though! Usually I try to shift to Lo when I am stoped but sometimes it wont go unless you are moving so you have no choice but to roll as slow as possible.

[Scott K]

On Fords you need to be in nuetral, foot on the brake, and vehicle speed of less then 5 mph to shift it in low. Better if you are stopped!

Not all vehicles support shift on the fly 4 wheel drive. Our Suzuki didn't.

My Geo Tracker 2 door convertible (Suzuki Sidekick) I could shift into 4HI while in gear driving. I think as long as I was under 50 MPH.

[DrKen]

depends on the type of transfer case. Some allow shift on the fly and some don't. Example- Jeeps have or had 3 different transfer cases. Command Trac could shift to 4wd on fly but did not have all surface 4wd and if you used it on dry pavement and did a lot of turning you could bind the case up even in 4 HI, Selec-Trac was a shift on the fly and was a all surface 4wd in 4hi and only drove front wheels when rear slipped. In 4 lo it was slippery surface only. Then there is quadra trac a full time all surface 4wd. You could put it in 4lo or neutral as a option and low is a slippery surface only 4wd. Other manufactures have there own versions of each and in addition there is the older original 4wd where you have to be stopped in nuetral to shift to 4wd and it is all slippery surface only. This is usually only found in trucks. Read your owners manual to find out which is right for your vehicle.
