never ever said i wanted to take my jeep in 4wd on dry pavement 'normally' never ever said that re read the post ...all i did was say i wanted to test it in my parking spot like 3-4 feet big difference between a quick test and driving down the road in fact i clearly stated i didn't want to drive it in 4wheel on normal pavement. I was preparing just to test it, and leave it in 4h as i was in fact going to be in some rough off road conditions.

I do sincerly appreciate the tip, i'd hate to destroy a new jeep.

that said, on a different subject, how does one handle this??

so for when i return to ny highways,(out of town now) upstate I normally encounter conditions where say there is a dry patch, then some ice, then snow then this repeats, I can say for sure if your not in 4wheel you won't make it, over the non dry parts, and there is no way your going to shift back n fourth, constantly,

so your saying that while you hit those dry pavements spots, thru a long say 50mile drive this would damage the jeep? I'd like to think it could handle this, seems odd to think it couldn't safely do this but not sure. is it truly black n white either i am deep in snow /4w or 2 and dry? My road conditions don't match this.

I'd also guess constantly shifting 2h/4h would be bad. I totally understand you don't want to normally cruise around in 4h --i get this-- I don't want to damage the jeep, i also don't want to slide off the road.

So in those conditions i'd be going maybe 30-40mph but wonder what wrangler folks do in these varying conditions, i mean I might not even be able to see ice until to late welcome thoughts...

Having good tires w/ good tread is more important in your described situation and it's better to keep in 2H. I think you really should be looking for a vehicle with AWD.

Keep it in 2h and slow down. Using 4h on dry pavement is dangerous to your drivetrain and to you. On a straight piece of highway, the effects are unnoticeable. But, the last thing you want to do is lose control due to some mechanical failure while going around a bend where there's no ice.

ahh ok, so my bad, i fall on the sword--I thought for a little bit i'd be ok, in rapidly varying conditions dunno why i thought that, i was wrong.

so no problem, since I have other vehicles that are more suited to that , that i've been using, they work fine, just wanted to use the Rubi more daily driving up there, since i like so much, but i'll keep it for more strictly off off road, which is mostly why i got it, but figured i could squeeze some more daily out of it, so i'll fix my head my other vehicles are more awd i have a awd/diesel and a awd beater and some other junkers. They all have snows and some studs too ..



thanks guys, my head is straight now, i was a little unclear on a few things appreciate your pulling me back in before i did anything bad owe ya

So just to be clear, we are NOT trying to 4wd over a hurricane, right?

 

[photo2000a]

I got it, was just misguided , on dry or rainy stormy normal pavement no, i'll stay in 2w--i'll learn my lesson, but if i am needing to go over small down trees, winch someone out, deep mud, sand gravel and rocks and i start slipping, maybe 4w. i am a first responder and sometimes have to go 'off road' in urban conditions -- but with that wacky one off exception aside, i am clear just plan ol 2w for the streets no matter what . lesson learned .

appreciate the double check & hand hold mwilk012 !! hope i can repay the favor

For tropical storms and Cat 1 hurricanes I use 2H. I only put it in 4H for a Cat 2 or 3 hurricane. In case of a Cat 4 I generally use 4L. And of course for a Cat 5....fully locked and sway bar disconnected. You have no business in a Cat 5 with a sport or Sahara. This is basic Jeep shit.

If you are driving in conditions that warrant the extra control of 4WD then use it. If the conditions are that bad you will likely be going slowly anyway. Many people new to 4WD love the extra traction, but forget that it only good for GO traction, but will do nothing to help you stop.

 

[The Fixer]

4H is fine for slower speeds (below 40mph I believe, but you wouldn't be going that fast in a hurricane), especially if it's slippery. And if you're not turning the wheels too tight induce binding, the transfer case should be fine. Obviously, since you have a Rubicon, you already have All-Terrains and plenty of ground clearance. But I have to say to those who say you'll blow up the transfer case or whatever you might be thinking happens when you're driving on dry pavement in 4WD, you guys have obviously never seen Camp Jeep at the NY International Auto Show. They run Rubicons ALL-DAY over all sorts of DRY obstacles and DRY pavement for a whole week. They run in 4LO with lockers off and swaybars disconnected. Yeah, it binds when you go around the corners, but I'm pretty sure Jeep is not replacing transfer cases after every event.

See my video here, and ignore the lame iMovie music if it bothers you -

If this makes you feel any better. I had the truck stuck in the front yard today while pulling the trailer up the hill so I could was them both. Popped it into 4WD and away we went. It was a beautiful sunny day in Tennessee. My diesel spends a lot of time in and out 4WD. I have been stuck at a stop sign in the rain while pulling my car hauler. The oil and. grease on the road, the weight of the trailer and the low end torque amount to going nowhere fast.

My advice is ignore the sky-is-falling comments and run it in 4hi. YOU'LL BE FINE, and so will your Jeep

Done this plenty growing up in snow-drifted parts of Colorado all my life

Went to the ny auto show all the time to shoot it on press day, great being there w/o the crowds. Haven't been to the last few thou. I've had the same problem in my pick up as well, has a similar shift 2 4h 4l N and hub twist lockers, loads of oil ice snow, and pulling trailers or plowing i normally just left it in 4h on those days, my thoughts there was prob wasn't efficient, but not damaging gears my older pickup is from the late 90's engine/tranny perfect , but normal driving was 2h, 90% time-- that said next time i speak to a jeep engineer i'll pick his brains on some things just to learn a bit more, I believe what the others said about the normal stuff but normally roads are fine so 2h is great, 4 for the tough stuff. but the engineers can fill me in on exceptions to the rules pro's and con's of this/vs that, beyond what the manual says....appreciate the counter points just standing by might deploy to 2 or 3 different areas soon... but will get picked up. So locked up the cars and finished up putting some JL under hood lights.

I hope you weren't constantly climbing in and out to turn those manual lockouts. You can leave 'em locked forever if ya want....and honestly I NEVER unlock 'em in my '11 SuperDuty.

I need to climb a steep driveway once a week and the light rear end turns it to washboard city if I'm not in 4hi. Ironically the only time I might unlock would be 4lo backing a trailer.
