When do you use 4WD?

My final word on it and I'm done. When traction is lost, they just all slide together. Been there, done that and slow down accordingly now.

I agree, connected or not the only way to not f%$k up on a slick road is to keep speed way down. It's amazing how many dumbasses pass me in the winter cause the think they have "4wd" and that means slick conditions don't matter. Funny thing is I pass about half of them back a couple miles up the road. Think I'm going to pull them out? Hell no they need to learn a lesson.
 
Well, it’s finally snowing in Minnesota! Since it’s my first winter with the Jeep I don’t really know how to use it properly.

Today I wasn’t getting any traction with just rear wheel drive, and taking the back seats out didn’t help to put any weight back there. I switched to 4-Hi within the first couple minutes of driving and kept it there for the rest of the drive and it worked great.

Even on the freeway it worked great in 4-Hi, but is there a certain speed that I should not be exceeding while in 4-Hi? I understand that 4-Lo is only for off-roading purposes. I also never use 4WD while it is dry, because there would be no need to.

In what scenario should I be in 4-Hi?
Yesterday, I just took my entire morning commute in 4H. Pretty much any time the road is slick, I'll do that. The snow was cleared up by the time I went home, so I just went back to 2wd.

There are some points during the winter where the roads are salted and clear enough that I don't bother with 4w, even when it's still plenty snowy out, but pretty much any time there's reason to slow down (resulting from road conditions), there's reason to go into 4wd. Better safe than sorry.


The use of 4 hi is limited by the safe speed of the low traction conditions under which it is employed. At no point is 75mph safe if the use of 4 hi is necessary so it doesn't matter what the safe speed is the rig can handle without mechanical damage. In other words, if the road is good for 75, you don't need 4 hi. If you need 4 hi, you won't be doing 75.
Yea, pretty much if you're driving at a slick part of a highway at a low speed/in 4wd and then later get to a clear place where you can continue on at 75 or normal highway speeds, you should just shift out of 4wd to continue.

HIs point is that the front axle and driveshaft are always turning, whether in 4wd or not. Meaning the front axle is designed to handle the same speed as the rear.

Yeah, perhaps me using the word “live” is a little overloaded unintentionally. Front axle and drive shaft is what I meant to get at.

I re-read your original comment to try to understand the context, and I think I see what you mean now. Driving at speed in 4hi is not much different mechanically than 2hi, because everything would be spinning at that speed anyways (or very close to the same...).

4wd does introduces the ability to bind the drive train due to unequal wheel speeds (turns) if the surface does not allow some slippage. Hence the 'never use 4wd on pavement' rule.
 
I’m use to work for Waffle House.. if some of you don’t know, it’s 24 hr restaurant mostly in the southern and open during rain, sleet , hail, snow, hurricanes, whatever... when it gets cold in the south, and snows or rains you get a heavy amount of ice on roads, “black ice”.. I still had to get to work and also get people to work cause we would be busy as shit those days, I’d would take my Jeep and would put in 4 hi during those ice storms and sometimes 4lo base on the hill I had to go down or up and never had one slip or slide, of course I was driving carefully but was extremely impressed with how well the Jeep did in those situations...

Damn, I wish we had Waffle Houses up here. I love that place, but never lived close to one.
