Re: Out of 4wd Hard
I would agree with you if only talking about 4WD LOW. 4WD High is another
matter. My Subaru is WD and I have NEVER fishtailed, slid, slipped, etc on
wet roads. Every 2WD car I've owned will slip and slide on wet pavement (I
like watching Mustangs in the rain). 4WD increases the odds of a tire
finding a non-slick surface...

Hi Joe,
Apples and oranges, your transfer is made to run on pavement.

powered by four cylinders.

Re: Out of 4wd Hard
Hi Jeff,
I was always under the impression that if you
go 4wd on hard pavement, tis ok AS LONG AS
you do not do any turning. If it's a straight stretch
and smoothly paved, there really shouldn't be any
bind, no?
Judging by the post though, it SOUNDS like he
has some bind coming out of 4wd. But my guess
(just a guess ;-) is that it's just in need of some lubing.
Maybe a better test would be for him to go on some
grass, or gravel, and check it that way..
Also, I think shifting into 4wd (high only) at 50 is
just fine. Although I think it's in the upper end of
the limitations there. I usually drop to about 40
if I'm going to do a "shift on the fly"

Not around here. I want to be keeping up to the transport trucks, if
they are running 60+, I will be running 60+ in 4x4 for sure!

That is true to the point that the front and rear axles have the same size
tires (worn the same, not the same size, per se) and are geared the same
(the 4.10 gearing of the rear is 4.11 on the front). These differences are
small, but real. The tires can slip on the ground to disipate the resulting
stresses that come from the small differences, but the stress are not
disipated on the street, and they build up in the tcase, and the tcase can
let go with a bang when that happens.
There will be less stress on a straight road, this is true, but that only
means the bang will be smaller.

I don't think the speed has anything to do with the "problem" either, except
that 4WD for 10 seconds at 20 is not nearly as far as 4wd for 10 seconds at
55, so any difference in the tires and axle gearing will be compounded by
the time quicker at that speed than if the speed was only 20 on the same
road surface.
I forgot to shift out of 4WD one day when I first got my Jeep, and as I
approached 45 and went to shift, the front locker and the tcase got together
and sent me across the road, and the steering wheel fed me some input that
the drivetrain was not happy at all. My immediate selection of 2WD was
smooth and effortless, but the gear driven D300 tcase works much differently
than the chain driven NP231. I would not be surprised if the chain caused a
loud clunk when it was released.
