    What are the scenarios I would use 4H? It looks like you can drive slow freeway speeds in winter conditions in 4H?

    What is H2? and what would you use that for vs staying in N and having 2WD like in normal daily driving?

    Any help would be great.

    Umm... lets see.
    2H is dry pavement, no adverse conditions day or night.
    4H is adverse conditions, low traction due to ice, snow, mud, insect migration, mud, cow shit, etc.
    4L is the fun stuff.
    And well, 'N' is neutral, that's no fun.

    I was under the impression it sits in N on the transfer case, but looks like its 2H. I've taken it up in the hills and wheeled around but looking it at it the other day, for some reason assumed it was in N.

    Who drives in the snow in 4H?

    I did the whole way to work today, roads were compact snow and ice with only the intersections being slushy.

    Of course, depends on how much snow we're talking, but if you do need extra traction, 4H is generally where you should be in the snow (unless we're talking about one of those rare times when 4low might be needed to be able to use the locker or something).

    If your trans case is in neutral,.. you won't go anywhere,.. just like your transmission.. if its in neutral,... welp.... just sit and rev.

    Edit- do you wanna go more than 10mph? But in 4wd? Then 4h it is. 4l is for crawling/geared lower.
    And yes, I use 4h for highway, shit roads. Aka wanna drive, with 4wd, but go faster, speed wise. Not rocket surgery or brain science here.

    I'm thinking OP might have a Limited with full time awd, so that right there might be the confusion here. That said, RTM:)

    I drive often in 4H at 65mph when there's snow and slush on the road. No problems. It's turning corners on dry pavement where you run into binding.

    If you have a limited, you shouldn't need 4H unless the snow is deep.

    I just went barreling around in some snow today in 4H just for fun. The runner gets around really well.

    If it’s snowing and slushy on the road I’ll drive in 4H. Figure the added benefit of the front wheels pulling can’t hurt.

    I’ve driven the Shasta’s and Siskiyou’s in snowy conditions and fun 4H and a speed that’s comfortable.

    OK, so if we're talking a Limited with fulltime 4wd, then 4H is locking the center diff. Somebody with more knowledge of the Limited's 4wd system can chime in here but I believe that in 4H it's no different than an SR5 in 4H, so not for use unless off road or on a slick surface. I would guess that for a Limited on-road, even in snow, leaving it in full time is better for most circumstances.

    Gospel right there. One trip I was passed by a power wagon pushing 60 at the least. Few miles up the road he’s 1/2 way up an embankment ass backwards and axle deep in snow.


    Tires help a lot too, my STi with AWD couldn’t get any grip in snow or slush with the performance tires. Made for a lot of fun drifting though.

    I think you have more control in 4H in snow. Having the front wheels "pulling" you in turns is more effective than the rear wheels "pushing" alone. Especially when you're running a siped, all-season tire.

    If it's slippery and I'm trying to avoid rear ending a stopped vehicle ahead, I'd MUCH rather be in 4H than 2H. Rather than continuing a slide, sometimes it's better to give a little gas and attempt to turn away. Maybe a front tire will grab.

    Now, there's about a thousand variables at play here, and there no one size fits all answer. But I can say I'm much more comfortable in 4H in slippery conditions. No question.

    Do you "need" 4H to get around? No. Is it safer? Yes, I think it is.

    This last snow storm I probably drove 75 miles in 4H. I also drive 10 miles a month on a straight road in 4H like my owners manual says to. YMMV.

    In my manual it's only advised to use 4H for 10 miles per month to lubricate the front diff. Engaging 4L doesn't exercise or lubricate anything that 4H does, does it? I do suggest engaging/disengaging the rear locker occasionally as well though, just to keep it able to move... which would of course require 4L being engaged to use anyway, but doesn't require actually driving the 4R at all, simply working the pins.

    I try to use 4H every few days on straight roads when I have no other traffic around me, for brief stretches at ~45 mph. I don't want to do it around other drivers, because ya never know when you'll have to turn sharply to evade some other bonehead, and bind up. This has helped my transfer case become more smooth, and now 4wd engages smoothly- when it was off the lot, the lever was janky, and my 4wd dash icon would flash a looong time before indicating it was active. Sometimes, it would go completely back to 2H. It's smooth as butter now, though, and works as intended.

    Way safer in taking corners as you can pull your self in the direction you want to go.

    Ok, I definitely win the Darwin Award for the day. so I was reading this thread early this morning, and realized I haven't put it in 4 high in over 6 months. So I put it into 4 high planning on only going a few blocks, but I got distracted and ended up leaving it in 4 high the entire duration of the trip. I went on a highway and was doing a good 65 mph for most of the trip. It was like a 20-minute trip there and back before I realized it. No big deal or did I risk damaging something?

    You're fine. If you didn't notice any binding you probably didn't turn sharp enough to cause any damage.

    At higher speeds and cornering, would you rather be in 2wd or 4wd? I'd rather be in 4.

    Noob question but when driving in heavy snow and having to park in it, would you just leave it in 4H instead of having to reengage 4x4 when starting again ?

    Yep, I'd just leave it in 4H, unless you're sitting on dry pavement.
