Did the 82 and 90 have tall gearing? That makes a difference too.
5.38s are much easier to break than 3.07s on a 4-banger.

You got lucky and it's a fine testimonial to the durability of the product.
Consider it a lesson and treat your Islander better. Every day's an opportunity to learn a little something and become a better wheeler.

I'm cracking up at the people in this thread that try to justify using 4WD in a downpour. Traction should be the last thing you should be concerned about in a downpour. I'd be more worried about getting water in the airbox or getting my distributor wet than traction.

In all my years of driving on roads, highways and interstates I've never heard anyone say 'Gee I lost traction I wish I had 4 wheel drive.' 99% of the time the problems people have are soaked distributor caps and airboxes.

Neither 4High or 4Low are designed for driving in the rain or any paved surfaces no matter what the weather conditions are--period. Stop trying to convince yourselves that you're doing the right thing. 4WD will not stop a vehicle from hydroplaning. Driving under the posted speed limit is what stops hydroplaning. If you're hydroplaning that means you're driving too fast--you need to slow down or pull over until the rain lets up if you're hydroplaning that bad because your tires are bald.

If you've been happily motoring down paved roads in 4 wheel drive and nothing has dropped to the ground sending sparks flying count yourself lucky. I've seen many guys' rigs sitting in the middle of the road waiting to be towed because they thought driving down the street in 4WD after mud bogging was the macho thing to do.

You don't have to take our word for it--read your owner's manual. Do your research in the internet. Or you can wait until you're stuck on the side of the highway with your drive shaft dug halfway into the asphalt. It's up to you.

I've driven down roads like this in my 1985 Volkswagen Scirocco. Lost traction every now and then but simply letting up off the gas and coasting until I felt the front end grab a little traction was all I needed to do to maintain forward motion.

Are you looking in the manual or the owner's "guide?" 2010 supplanted the owner's manual with a guide. The manual is on the DVD they gave you. You can also download it from Jeep.com

First of all you did not have a 1982 Wrangler. Wranglers weren't introduced until the 1987 model year. (Mid-'86). You had a CJ. Some Jeep models, including CJ's had a full time system called Quadratrac. I

I can't believe the fact that this thread is still going ... or the number of people who think their Jeep is going to fall apart if they drive it in 4wd ... LOL!

I think the owner's manual is pretty clear. In fact ... if any of my previous posts contradicted it in any way, please ignore them and go by what it says

I wish I could answer your question, but as I have professed before, I know nothing about the inner workings. Can't tell you what my current one has either. I just have fun in them.

You are right, and I have learned a great deal from this thread. I'll exercise more caution in the future, but like the poster below us, my experience is the sky is not necessarily gonna fall from using it in less than needed conditions

Hilarious. Oh oh oh.... Funny thing(well not so funny)
This rubicon guy punched the skinny pedal to hit this creek wall to get up it. His front end bounced, then he wound up ontop of his hardtop thus smashing it.
I had to tow his ___ out and then show him how to properly do it. Popped it into 4lo and crawler up the creek wall.
Then he felt stupid.... Needless to say je was a flaming noob.

Here is Why Part-time 4WD Should Not be Used on Pavement:

If you own a vehicle with part time 4WD the need for different rpm front and rear represents a major problem. The transfer case will power the front and rear drive shafts with same rpm and is not able to satisfy the front axle's need for more rpm. Remember, the combined rpm of front wheels (A+B) is higher than the combined rpm of the rear wheels (C+D).
Only full time 4WD systems are able to negotiate the needs of front and rear.

So, with part time 4WD engaged your front wheels are forced by good traction on the ground to rotate faster than the rear - but since the front drive shaft delivers only the same rpm as to the rear there is a fight between front wheels and rational force coming from the front drive shaft. The front drive shaft in effect tries to slow down the front wheels. This results in very wide turns (understeer) and dangerous handling on pavement.

The name "part time" derives from its use. It can only be used part of the time - most of the time (for most uses) it has to remain in 2WD. Only "full time" - notice the name - can be used full time for all uses.

The fight between front wheels and transfer case also makes 4WD performance suffer - the front wheels are not pulling like they should. They are in effect hindered by the front drive shaft.

The slowing effect caused by front wheels stresses all components between wheels and the transmission. It causes mechanical components to bind instead of moving freely - this situation is called "axle binding" ,"driveline binding" or "driveline wind up". First indicators while driving is a hard steering feel and the vehicle displaying jerky movement. Shifting back to 2WD will become impossible (gears and levers are extremely forced together). Continued 4WD use on dry surfaces will cause the weakest links to break (U-Joints, axles, differential gears, transfer case gears and chains, bearings, drive shafts).

When starting from a standstill with sharply turned wheels: The need for higher rpm in the front will most likely prevent you from getting started at all. If you step on the gas really hard (plus slipping your clutch) you might get the vehicle moving with spinning rear wheels but stress on all driveline components will be dangerously high. Chance is that you will break something.

When traveling with part time 4WD on high traction surfaces like asphalt, concrete, etc. handling of the vehicle will become unsafe (understeer) and the "driveline binding" will eventually cause component failures. Part time 4WD should not be used on high traction surfaces! Even when going straight most of the time, slight differences in tire pressure front to rear or vehicle load resulting in different axle speeds will cause "wind up" and eventually damage.

When traveling with part time 4WD on low traction surfaces like sand, gravel, mud, snow, etc. handling of the vehicle is unsafe (understeer) as well, but not as severe as on pavement. The slowed down front wheels simply skid a little on gravel, sand, snow, etc. during a turn. This in mind you should always approach difficult off-road obstacles in a straight line otherwise you might lose some of the much needed traction due to wheel slip on your front wheels.

Do not listen to guys who tell you it is OK to use part time 4WD on pavement! Severe damage will be the result.

Here is another important fact: Since front and rear axles are not able to rotate independently ABS will not work properly.

My sincere apologies. I'm learning, and this looks like the right place to do so. This is probably the point in my profession where I would have told the end user to pack the equipment up and send back to the manufacturer because they were simply too stupid to use it. Thanks for bearing with me

You know, mine had some decal on the hood too but for the life of me I can't remember what it said. We tore that thing up in every way possible in HS, but the darn thing just kept running!

I remember rolling several times. I remember the top was so worn and tore up i couldn't put it up anymore. I remember my buddies all riding in it to and from school, even when it rained. I remember taking the backseat out and replacing it with a keg and being a rolling party on Saturday night. I remember driving it down the ramp into the lake and having to get pulled out. I remember driving down the beach of corpus with 3 topless girls standing in the back waving to people on the beach my sr year. I remember "trenching" peoples front yards that I didn't like. Yeah daggo, I remember my first jeep. Staying with this thread, I'm trying really hard to remember, but I can't honestly say if I ever took it OUT of 4wd

Hmmmm.. I am not sure I agree with that... I will and have used 4 wheel drive in heavy rain. I feel that you will get significantly more control in 4wheel drive and greatly reduce you chances of hydroplaning or sliding.

However, I do agree that 4 wheel drive is a license to go faster in poor conditions. You should still slow down and drive with caution.

Just my 2cents

You just contradicted yourself. A wet paved street is not going to give the wheel slip required to be in 4WD. Couple that with tires that do well in wet conditions and you have a recipe for disaster.

I have seen so, so many "oh, don't use 4WD in the rain" comments, and while I'm sure you're thinking about protecting your 4WD, but the fact ... and yes I DID use the word "fact", ... is that hydroplaning is generally caused by a 2WD system - the rear tires "surfing" the front 2 dummy tires.

When in the rain, "YES" you use 4WD-high ... It gives your front wheels "power", like the rear wheels, so hydroplaning is almost eliminated.

*NOTE: the reason most folks say that a part-time 4WD system (Wrangler types, etc.) is because the tires have no tolerance in this type of 4WD system for "solid" pavement. On the dirt, gravel, heavy rain, there is "slippage". On pavement, usually there is not.

Test this and see:
In a parking lot, put your Jeep 4WD into action (low or high) and drive a few parking spots to make sure everything's engaged. Then try a tight turn into a parking spot. "There"! Feel that! You have just experienced what some are concerned about.

Does it hurt to use it on-pavement all the time? No, but you'll be replacing your tires a lot faster! It can't be good for the system on dry, solid pavement, but if there is "slippage" ... if the road surface us "loose", or "wet", "muddy", etc. then GO FOR IT!

Oh, and HAVE FUN!

P. S. THAT is why 4WD is "standard" and not an "optional add-on" with a Jeep!

Your P.S. is BS. The manual specifically says not on wet pavement. I also disgree with your hydroplaning theory. Please explain why FWD vehicles still hydroplane.

You're right. Why should I care what someone does to their Jeep? Just don't come on here crying after you tear up your drive line. Just ask Silvrevo, I'll be the first to say I told you so.

If a group of women were having a prolonged debate, and a man walked in and said: "Boy, it must be that time of the month" that dude would have been tarred, feathered, and run out of the country.
