|TRJK||I'm out before the plows most times, and I've found dropping it into 4Hi to get going, and then popping back into 2hi for better steering once at speed seems to work well. I just feel better that 100% of my front wheel traction is for directional control and if i start spinning or see some real deep stuff i've got the 4wd card yet to play. I've also got the stock mud terrains which are spectacular in the snow.|

I'm comparing my Jeep in 2wd to my Jeep in 4hi... after thinking about it for a second, I guess my observations are more during slowing down such as for curves or intersections, not so much as the actual stop. At that point you either stop or slide depending on traction.
"IN THEORY, if you're actually under power while braking (which is not good practice),"
Why would braking under power (in gear) not be good practice. Do you clutch everytime you apply brakes?
"you might have to apply more braking before it overcomes the engine torque AS WELL AS the tire friction, but that really doesn't help you stop any sooner."
Agreed, overcoming engine torque (completely)would be a stall and overcoming tire friction would be a skid. So this is the threshold I'm thinking of, the engine torque, while slowing down is resisting the brakes locking in a low traction situation. Until you tromp on the brake, then you're done anyway...
"Engine braking really doesn't help either, that just adds a different source of drag other than the braking system; the tires will still lose traction at the same point, it just takes less of the brakes to reach it."
I know what you're saying but, while slowing down, I've never experienced a wheel lock while engine braking. And that was my specific observation, wheels not locking up as easily in 4hi.
still, i'm not advising anyone to go barreling around unsafely in 4wd just that in a plain old Jeep with nothing electronic to help you not do something stupid (like yours too, i believe) 4hi and good threshold braking skill will get you pretty far.

In theory (and ABS notwithstanding), the type of drive should have no relation to when the brakes lock up - it's a simple matter of the friction between the brake pads and discs (or shoes and drums, as the case may be) surpassing the friction between the tires and the road surface.
IN THEORY, if you're actually under power while braking (which is not good practice), you might have to apply more braking before it overcomes the engine torque AS WELL AS the tire friction, but that really doesn't help you stop any sooner.

not wanting to start an argument about 4wd stopping and based on 8 winters here in my current jeep, but it has always felt to me in my TJ that having power going to all 4 wheels SEEMS to keep wheels from locking up when braking in snow... this is without ABS of course. I'm only talking about normal city driving around Ottawa and the valley where the plows don't come out till morning.

|Newbsauce||We got about a foot of snow today. Had a blast cruising around town. Good times...|

|Soundy||Just remember, 4x4 helps you GO better in the snow... it won't help you STOP any better.|

|brendo||middle of winter in calgary with the 07 4dr unlimited.... love it. i dont use the 4x4 unless i have to and i never switch into 4x4 unless stopped and in N. habits i suppose but ive never been stuck and i have a tendency act a fool in the snow haha. ive been blown away by this vehicle and wondered why i didnt get one sooner... JFL|

|Sebas||Yep in 4x4 expect eratic turn at slow speed. Got a 2012 first winter with jeep got 4 winter tire and it will get you anywere. You can go yo 4wd at any speed up to 80k above that I think your driving to fast in the snow anyway. Live quebec and love the winter. And the new YJ as traction control and stability control. It will not fish tail on you even if you try hard|

With my 07 I drove 135,000 km in 3.5 years and loved it. Key thing is be careful at slow speeds in dry parking lots in 4x4... It will jump around if you have the steering wheel pinned one way or another.
And definitely driving at hwy speeds in rear wheel drive when the weather changes on you.
I think the manual recommends not switching into 4x4 over 70km/hr... I alway took my foot off the gas and had it 40-50km max... To reduce stress on it.

Just bought My first Jeep in July 2012 (Sahara Unlimited)and the dealer told me that you can switch to 4x4 on the highway but they recommend easing off the gas when you just to take the strain off the system. Also winter driving is more about common sense then it is the vehicle. Best Suv in the world is no good unless you have good tires and good driving habits
Hope this helps

|CanadaCurt||Thanks for all the input. I appreciate it. I live in Edmonton so we get a fair amount of winter weather. Currently I drive a small FWD car but routinely drive a RWD pick-up for work. Gives me something to think about, thanks again.|

|TA462||Jeeps are great in the winter time but you still need to drive with caution in bad weather. So many people drive like morons in their 4x4's in snow storms. My 99 GMC Extended cab 4x4 pickup is a tank that will go through just about any amount of snow. I just can't stop it, lol.|

|dama417||Jeeps are great in winter, as are most SUV's. that's what they are made for. The big difference is with 4X4 you have a rear wheel drive vehicle until you put it into 4WD. So if you are use to Front WD, that may take a bit of practice.|

|LoneHowler||I was dumb enough to do it once in a ford explorer before I knew how it would handle in 4x4, its not meant for high speed.|

Care to explain the "dumb enuf to turn on 4x4 at highway speeds" comment.....
I've driven mine in 4x4 at 110km/hr and never had a issue. Buddy wanted to know what they we're like in winter. He didn't want winter driving tips from mom....

When you get your jeep take it out on some gravel roads and learn its braking and handling, gravel will need longer stoping distances and give you a bit if skid, not as bad as ice but it will give you a bit of experiance before the first snowfall.
When the first snowfall comes take it slow
Edit: if you are going from a small vehicle to any large SUV there is quite a difference in handling and stopping distance. Again get to know eachother on some country roads. It's a SUV it deserves to be broken in properly, Have fun!

I've had three jk's now and they have all been great in the winter time. But your tires will also play a huge part in how well it does in the winter time.
The stock tires are decent all season tires. But if you want a great winter jeep buy some GY duratracs or some full winter tires.

Driving Jeeps In Winter
I'm new to the forum, considering picking up a 2012 Sahara. Was just curious how you guys find that they handle on snow and ice? I'm in Edmonton and would probably end up using it as a daily driver and am skeptical of buying one for that reason. Thanks!
