Using 4Hi on black-top..

Tokyojoe · **Posted:** Mon Feb 25, 2008 11:43 pm

Part time for slippery conditions and if you need to go straight with traction. Like at an intersection going up a hill during slick/icy conditions and you have to stop on it at the intersection.

Just pop it in and out of 4 hi as needed. I just went over Vail pass through a blinding snow storm 2 days ago, and was able to pop it in and out as I saw fit i.e. passing a semi. The nice thing is, we do not have to worry about having to get in and out to lock the hubs. It used to be such a pain in my old bronco to get out to lock up. Although, it was nice that the hubs were definitely unlocked by a manual twist of the hub. I love the basic 4 wheel drive set up, but I am sure I would really love the selec-trac with the full time option.
Also, we manual owners get a beefier transfer case than the autos get, and I imagine they are less prone to breakage....

Yeah, I second that ( not on dry asphalt ofcourse! ).

All these pics and stories made me so nervous I refused to use 4hi / lo on my first ofroad adventure. Because I was afraid I'd break it. Which surface is slippery enough? I figured it out while rolling backwards on a snowy slope in 2wd

Now I just flick it into 4hi or lo whenever I am ofroad and think I need it. I love the 4lo.

Yea, the 4 lo is what seperates us from the 4x4 wannabes who just have awd i.e. rav4, element, etc.
Plus, with your crd you have all kinds of great torque (jealous!)

um....haha that sucks....i use 4 hi sometimes on the road but never when i havent needed it. I hope thats from extended use and not just one time on dry pavement.....haha

That pics was from Jeep driven 150 miles in part time.But it can happen at anytime,I have seen a t-case shatter in 5 pieces from 10ft of travel,happened while backing up.

I blew a rear differential in a '76 scout by driving over a short section of solid rock (15 or 20 feet) positioned right on a bend in the trail, in 4-lo. I think the diff was on its last legs anyway: I had noticed quite a bit of endplay in the input shaft before this happened, but I'm sure it was the stress of making that turn on solid rock in 4 lo (and it was steep enough that I'm not sure I could have negotiated it in 2 high if I'd tried) was what finished off that differential. As I was going over the rock, I heard popping sounds from the rear end, and from then on it would pop on every turn. When I put it in two wheel later, the rear diff failed completely immediately. When I checked it, there was a hole in the access cover and I could see loose gears inside the case. I had to tow it to a shop and had a used diff put in.

So, 4 wheel full time is fine for dry pavement right? 4 wheel part time is only meant for slippery conditions, and off road NOT dry pavement? and of course the amazing 4 low is for real off roading?

yes 4wd FULL time is for pavement 4wd part time is ONLY slippery or off road and then 4 low is mainly off road only and at LOW speeds

I would like every one who is saying that using 4wd part time ,or 4wd hi or low on a 231, to think for a minute
I have been places where I was getting so much traction that I was smoking 3 wheels and would have been 4 had it been touching to me that is not a "slippery surface"
now under the same conditions I have had to turn going forward and backward at full lock in a TJ with a Detroit in the back and an ARB in the front
nothing broke
There is no reason to put "the fear of god" in to people like this
simple fact is this
do not use 4wd under any condition unless there is 8"+ of snow on the ground or you are off road
If some one has a 242 and does not know the difference between full time and part time then that person should read the little book in the glove box

If you are "smoking" 3 wheels you have zero traction,sorry but that is just common sense there------Wheel spinning,AKA "smoking the tires" = zero traction.

Running in 4hi or 4low at 5mph for maybe 1 mile or so is alot different then running 4hi(not so much 4low since you can't get it that fast) at 75mph for 50+ miles.

smoking as in burning rubber
like a drag car burns rubber
leaving a skid mark on the rocks
tires got so hot the rubber was melting
this is not a lack of traction but rather to much gravity

If you call spinning your tires and leaving black marks "traction" (the complete oppisite actually)I'd can only imagine what you call a "loose" situation :roll:

simple
dirt and rocks flying from tires

look I know what you are trying to point out and it has NOTHING to do with the point I am trying to make
my point is simple
people think that there transfer case will explode if the get into a "high traction" situation and use any form of part time 4wd
this is simply not true
If it were true than any one who has played in the rocks would have busted a transfer case
or I ,along with thousands of others, would have snapped axles due to them binding from lockers or spools
because it gives the same result as running open diffs and 4wd on dry ground
tires are forced to turn at the same rate and something has to give ,most times that give is the rubber on your tires

Now I also feel that if a person owns a 4wd any thing and does not take the time to learn the proper use of 4wd
remember I offered a 101 corse, gets what ever they get if they use it improperly

Anyone taking your 101 course would be worse off then before since you don't even know what "Traction" means,and like I said running 4hi at 5-10mph for short distances(1 mile or less) is not like driving in 4hi at 75mph for 50+ miles.Most drivetrain components will hold up to a certain amount of binding before breakage,stock components will not last as long as HD aftermarket versions.When offroad and on those high traction areas like rocks you are not on them long enough to usually build up enough binding to break stuff since shortly you will be back on dirt or mud plus when you raise a wheel in the air you un-bind your driveline.

Can I just say this again (its been said a few times by others), for all of those getting confused by everyones different opinions on "when" to use you different 4x4 options, READ THE MANUAL!

Khaki-KJ · **Posted:** Thu Jul 24, 2008 6:01 pm

The 2005 - 2007(?) Libertys with the manual transmissions came with the bigger NP241 transfer cases. I think that is ithe correct number, I don't feel like running outside and crawling underneath right now.

They only came as part time 4 wheel hi, 2 wheel hi and 4 wheel low. No full time 4 wheel hi with the manual transmissions.

I only use part time 4 wheel hi on road when we get the typical heavy BC rainstorms, or if it has rained after a long period of dry weather and the roads are greasy.

Mine didn't come with the manual. Darn used dealer!

The only time I used part time high and low on pavement was when I was testing 4wd on an XJ (selec-trac) and what I did was go into a parking lot and going 5mph or so I shifted to 4hi part time and then full time and back to 2hi and then stopped and went to 4lo. I stayed in a straight line and didn't turn the wheels and didn't exceed about 5-7 mph . There was no convenient dirt around and I was just testing it to be sure it was working ok. I didn't hurt it.

Other than that I NEVER would use 4hi (part time) or 4lo on pavement. Only in heavy snow or off road. I do have selec-trac in my KJ so I use "full-time" for everything elce.

Theres nothing wrong with that at all. Just dont turn and dont use part-time like it was 2wd.

You still where binding even though you never turned the wheels.The F/R diff are not geared the same,they may be labeled the same but they are not.The 8.25 has 3.73 gears and the front diff has 3.72 gears(though labeled 3.73's),just like like my 8.25 has 4.10's and the fronts are 4.09's.Ever actual 4wd vehicle is like this.

I doubt that most realize what you said TJKJ plus the fact that if even air pressure is different in the tires will even make it worse. I never put mine in on blacktop,( why would you???) well unless the blacktop is covered in snow or ice
