Well I can tell you my transcase does not like to shift into 4lo if I am doing the2-3mph crawl it suggests. I have an auto/Rubi and I need to be stopped and tranny in neutral and than it pops right into 4lo. If I try the 2-3mph roll ,with the tranny in neutral, the transcase make sounds that make me want to cry

I looked it up, and the owners manual says stopped and in neutral or rolling very slow in neutral. Again, thanks!

OK, lets get down to brass tacks--

Driving in 4hi/4lo, all depends on terrain/tires/hills/gear ratios/speeds and driver ability, but

The reason we're so uppity about the JK, is because the transfer case is actually shifted with a cable and an INFERIOR PLASTIC BUSHING, that often will, with a little force, will BREAK and leave the JK in "N" and it ain't going nowhere, unless you can fixit ONSPOT !!

Thats why I was pushing low speed engagement and the more the xfer case is shifted, (broke in),the easier it becomes-

And JIMBO ain't kiddin. Happened to me in NH and luckily not too far from civilization...only about an hour walk. After that I got 3 of those little plastic bushing suckers and put them in the glove box at a whopping 60 cents each. Now I've got one for me and anybody else who WILL get stuck occasionally...it is not a matter of IF but WHEN!!!!

I sure hope that they've changed it in 2011--

Does anyone know about this ??

Yea, I've got 5 in my glove box too, hope I don't have to replaceit ONSITE, although I know where the STUPID bushing has to go !!

Question: can you post the part number for that bushing? And what other spare parts and tools should I take when off roading in a JK? Thanks!

Hard packed sand or driving in existing tracks
Loose dirt or gravel
Anytime I am going over 15 MPH

4 Low scenarios
Deep sand
Heavy or deep unplowed snow
Heavy or thick mud
Steep Hills or rocks
Whenever pulling anyone or anything

When I am off road, I am generally in 4 high until something comes up. I change to 4 low and after the obstacle, I go back to 4 high.
If you use 4-low in deep snow or mud I bet 9/10 you get yourself stuck. 4 low has too much torque and will turn the wheels over 30% faster than 4 hi. If you are mudding, you need to be in 4hi or even 2wd depending on how thick the mud is. Most people don't realize that in soupy mud with a hard bottom all you need is 2wd.
My experience= Marine Corps 3533 (logistical vehicle operator, Humvees, 7-tons, Lvs, 5-ton, professional off roader.)

Not stopped. Barely rolling. If the ground you're on isn't level, you can stop, put the tranny in neutral, then slowly let off the brake letting it roll until you can easily slip the t-case into 4lo. The important thing is to not force the t-case shifter. Doing so will eventually break the cheap little plastic cap/bushing thingy that holds the cable to the shifter. It's only a 25 cent part (approximately, and probably a good idea to keep a couple on-hand), but it's just a pain that can be avoided by proper use of the t-case shifter.

Ok, I went back and read that link and wish now I had not. The advice on that sight basically says unless you are doing some hard core off roading then 4wd should never be engaged. If that wasn't enough, he says doing so will basically just damage your vehicle. He says you can use on icy roads, but to keep your hand on the shifter in case you hit some pavement popping up through the ice or you will do damage to your vehicle. This is actually my 3rd jeep, and in the past during heavy rains, I would run them in 4wh for 20+ miles and never did any damage. Yet, he bolds this quote:

So, when can I use my 4WD? One Jeep enthusiast who is fairly expert on most things Jeeps, Jerry Bransford, says, "... a part-time 4wd should never be used on a paved street unless it is covered in snow or ice. Not even when it's raining."

Thoughts?

Check this quote:

Ice - 4WD is great for ice, except that ice tends to come and go on streets, and you will hit dry pavement, and your 4WD will be engaged. I guess it depends on how much dry pavement you might go over. Occasional dry pavement patches will probably not hurt anything, but if you leave the ice, and you forget your 4WD is engaged, then you are in trouble.

You are in trouble? Really?? Did I just get lucky in the past running it in conditions he says will almost definitely cause damage? If I had never used 4wd ignorantly before and then read his advice, I would be not only afraid to use it but wondering why it would ever be installed on a vehicle that wasn't going to be climbing rocks in moab.

Thoughts? Jerry Bransford is a member here, and a Jeep Wrangler expert. Why don't you ask him? Seriously. Find him on the forum and give him the link to this thread. He's a very nice guy in my experience and will be happy to help you.

Interesting. That pretty much blows a good portion of opinions on this thread. While I don't pretend for a second to be knowledgable, as I honestly have zero clue of the mechanics, I can say that through 3 jeeps and roughly 12 years of jeep driving, I have grossly misused (and if this is true i do mean grossly) my 4wd over the years with never any damage. Now I'm stuck back at the beginning question I started this thread with, and have no more clue than when I started with the opinions so varied. Maybe I was better off being ignorant on the matter, lol.

So unless you plan to go hard core off roading, why bother having a 4wd at all? I used to scoff at the unlimited for even offering a 2wd, but that statement makes me wonder why 4wd is an standard and not just an option on anything.

It's not like you're going to damage the Jeep because you drove across 10 feet of paved road that didn't have ice on it ... this is REALLY not something to get hung up about.

If you are on a slippery surface and you feel you require additional traction, engage 4wd. That's what it's there for.

Oh no, please try to see some of my satirical humor in the midst of my confusion. I'm kidding while trying to wrap my head around something serious. We're not talking 10 feet, this week in Dallas we had a storm come through that dumped 11 inches of rain in a 24 hour period, and I drove in 4wh the entire ride home...27 miles and as far as I know no damage. This was pavement/freeway with a lot of standing water.

4 Low vs 4 High

I always start to climb in 4 High, usually 1st does the trick. It should become obvious when you really need the added torque of 4 Low.

So unless you plan to go hard core off roading, why bother having a 4wd at all? I used to scoff at the unlimited for even offering a 2wd, but that statement makes me wonder why 4wd is an standard and not just an option on anything.
The section I quoted from what Jerry said, has nothing to do with "hard core." I wheel all the time. It certainly requires 4WD, but would never be considered "hard core". I drive on the beach just about every weekend. I occasionally go in the mountains/woods where there is plenty of mud. This past winter we had several blizzards where I went wheeling on the streets. Trust me 30" of snow on unplowed paved roads requires 4WD.

The point to remember is that there is really no point in using it if the conditions don't require it. Nothing is going to help you on slick ice. You certainly don't need it in the rain. One thing to remember is that in 2WD, it is a rear wheel drive vehicle. I grew up with rear wheel drive, but have gotten used to front wheel drive over the years.

There are many people out there who have never driven a rear wheel drive vehicle. It handles a little differently in slippery conditions. I actually prefer it, but you have to get used to it if you're not familiar with it. That may be what scares some people into wanting to use the 4WD all the time.

I don't pretend to have the extensive knowledge that some of you have, and I for one am very appreciative for the insight you have all shared. Bit, I can't quite swallow the " never 4wd in the rain". Having grown up, lived and owned a jeep in Florida I know all too well the summer downpours that occur almost daily. Roads will go from bone dry to 2"-4" of standing water in only an hour.

Somewhere above it states if the rain forces you to slow down from highway speeds to 40-50 mph, then it is safe to use 4w hi. I feel this is right although I am no expert- other than driving in it a lot. This is probably how I'll continue.

I felt for sure that 4wd would help on ice. Although I don't have too much experience with it
