I just got a 2001 Jimmy 4x4 from my brother who never used the 4x4 feature, only
Since this truck has manual selection by push button of shifting into 4x4 mode.
My question is:
How wet does the road have to be before I should go into 4x4. The manual said DO
NOT use 4x4 on a dry surface but it does not indicate at what point it is safe
to shift into 4x4 ?
Also what harm will happen if I drive in 4x4 on a dry surface ?
This is a personal judgement thing, but I only shift into 4x4 when
- I've done something boneheaded and gotten stuck - as in making a turn into an
uphill street with 12-15" of badly-rutted snow/ice
- The guy in front of me has finally managed to get himself stuck on a hill and
I want minimal chance of fishtailing as I ease past him.
- I'm driving in sand.
- I'm driving in snow that's so deep that the vehicle keeps trying to veer one
way or the other (following some buried ruts??).
My rationale for limited use is that:
1) Handling is different with 4x4 engaged and whatever reflexes I have are set
up for 2x2.
2) It's more interesting to drive in snow without 4x4.
3) I don't think 4x4 makes me stop or stick to corners any better. Somewhat
the opposite, I think: 500 extra pounds to stop and/or go off on the tangent of
a curve. It might, however, give me a false sense of stability and confidence
and I don't want that.
I don't claim much knowledge in this area, but I *think* you've got what I call
"part time" 4x4. i.e. it locks up all the wheels when engaged rather than
having any sort of differential between front/back or left/right.
If you put it in 4x4 on a dry surface, you'll feel it in the steering right
away. That binding sensation is from the wheels trying to rotate slightly
different amounts. Seems like a reliable way to break your drive train. I
wouldn't even *think* of using 4x4 when it's just wet.
Judging from the responses in this thread (not just this one), it sounds
like most of you never leave pavement and bought 4x4 for bad weather on
public roads only?
I am off-road quite a lot myself, and like to engage the 4x4 at least
once a month or so at a minimum just to slosh some lubrication on the
parts instead of letting them rust up and HOPE that they'll be working
fine when needed. The land I have can get VERY muddy in even a short
but heavy downpour, and not having 4x4 is a guaranteed recipe for
I got mine cause it makes the truck pretty. The chicks dig it, man. I
never go off the road or tow a trailer or any of that shit. What does it
matter to you what someone else does with their truck? If you need it, you
use it. If you don't need it, its still available. There's a bunch of
soccer moms that don't go off roading. So what?? When I was in the
service, we were off road daily. I've been in every predicament possible
and was thankful for 4x4 to get me through it. In the civilian world, I ve
gone hunting in places that should have been by horseback. I've never gone
and beat my truck up cause its "fun." The people that do it cause its fun
don't present a problem to me. It their business, not mine. Maybe they
don't like building model airplanes or taking pictures. I don't care. What
I do with my truck (or anything else) is my own business. You don't have to
you don't really need to put a GM IFS truck in 4wd to "splash the
lube around" as the CAD only disconnects one axle, leaving the other
constantly driven by the road, turning the spider gears and spreading
the lube around. on the autotrac xfer cases, the front driveshaft
I personally bought my k2500 because I wanted it, and because mud
looks good on it's roof.
