Question about 1992 Jeep Wrangler

Don't know how to engage 4WD - No owners manual

Hello All-

I am not sure how to engage my 4 Wheel Drive on my 1992 Jeep Wrangler. I just bought it used and there was no owners manual. I am not even sure if I have automatic or manual locks? Everything on the Jeep is stock. Next to the manual shifter on the floor (5 speed 4-cylinder) is the 4WD shifter. Currently, it is at 2wd. There is also 4H, N, and 4L. Is it okay that it is on 2wd currently with no weather conditions? What is the Neutral for? What is 4h and 4l used for (snow and more snow)? And how would I engage it? I would like to use it for the winter if possible if we get some bad snow, but am afraid of destroying the vehicle since I have no knowledge of how 4WD is used properly! Any help would be greatly appreciated! Thank you in advance.

    Thank you so much! I have so many plans for the Jeep! I just have to wait to get all the gear! One more question though...do you know what the Wheel or Hub lock looks like and is there one on each tire? Thank you so much again!

I love driving 4x4 jeeps, especially in 4-wheel drive. First, a list of when you should and should not use 4-wheel drive.

2x4 Hi is for normal driving in most weather and anytime you are driving over 50mph.

4x4 HI is for getting you unstuck from mud or snow and can be used up to 50mph but is not recommended for much faster. It is only designed to get you moving and unstuck, it will NOT make it any safer to drive faster on slick surfaces like rain, snow, or ice. Always drive slower on these kinds of surfaces.

4x4 lo (low) is for extreme 4x4 driving like trail riding and mud bogging to get over steep inclines and deep mud without burning up the clutch. 4x4 lo should never be used to drive faster than 25-35mph and should only be used in off road situations.

Neutral (on the 4x4 shifter) is mainly used if you are towing your jeep with any of the wheels on the ground. It completely disengages the transmission from the drive train so you can tow it without damaging the trans.

Now, to shift from one to another. My jeep may be different than yours and I haven't driven my jeep in a while (I had to sell it) but it should shift the same way.

First, make sure you are parked and the wheels are not moving. Put the main gear shift (5-speed) into Neutral, hold down the clutch and move the selector from 2x4 to 4x4 by first pulling the shifter to the side then moving it up or down. Some jeeps (especially older ones) may have a wheel lock on the outside of the wheel hub (AKA hub lock). This must be in the "LOCK" position for 4x4 and "UNLOCK" for normal 2x4 driving. Make sure it is fully engaged in the slot before shifting into 1st. Then you can drive normally, following the guidelines above.

The regular 5-speed transmission will shift just the same as before but you will notice that the jeep will drive much slower in 4x4 lo and it will have much more torque for those really sticky situations.

Good luck! Have fun! And if you do plan on doing some real 4x4'in or mud boggin' make sure you buy a winch for the front of your jeep or bring a friend who has a winch on their truck to get you unstuck from the worst of the worst! Don't forget to rate!

P.S. if you have problems with one or more 4x4 settings you can always shift back to 2x4. Make sure that if you are driving on the highway or in normal driving conditions, you are always in 2x4.

P.P.S. If you are near the Columbia, MO area send me a PM, I'd love to find some new friends to do some 4x4 driving with in the area so I can get back into the sport. I miss it.

    The wheel lock hub looks like this: Here's a man working on the locking wheel hub with the wheel removed. You may not have one of these, many newer models have automatic locking hubs, but it doesn't hurt to look. The brand name is "WARN" on this particular model

It's easy, I have one myself. To engage your 4WD, put your transmission in nutral (take it out of gear), than shift your 4WD lever to 4H. Then you can chift back to 1st or 2nd gear. Your hubbs should be auto locking, so you can actually do this while moving. The diffrence with 4H and 4L is one is a High gear ( for faster moving across nasty turrain) the 4L, or Low gear, is for getting out of thick mud and things like that.

Note that all 4WD does is put drive power to all 4 wheels instead of just the rear wheels like normal, therefor 4WD really doesn't do much for snow other than increase the number of wheels with power to them to avoid fish tailing and getting going again from a stop. It does nothing for slip and slide prevention or stopping. It may help you get out of a deep drift that you mite have ran into or something like that, but that's about it. So please take care in the snow. A Jeep is a very lite vehicle and is easily manipulated by turrain surface conditions.

My 4 wheel drive does not work on my jeep


The term four-wheel drive typically describes larger passenger vehicles that may allow the driver to manually switch (sometimes with an automatic option) between two-wheel drive mode (if available) for streets and four-wheel drive mode for low-traction conditions such as ice, mud, snow, or loose gravel. It may not -always- work but is very reliable.

I have an 89 jeep wrangler yj, when i try to engage 4 wheel drive front shaft is turnin but front tires are not pulling. any ideas of might be the case? just bought it and prior owner i dont think used the...


If you have a square box mounted to the right front axle tube, make sure the vacuum lines are attached to it and that it's working. If it's OK, then you have likely either have a broken differential gear set, broken outer axle joint or axle itself. I'd bet on the vacuum hose though. They did away with that unit in later jeeps because it was always getting disconnected.

4 wheel drive doesnt work.


Has this Jeep been modified at all?
It sounds like the shifter cable was reinstalled backwards.
Specifically the 4-Low "Not Climbing Well". 4-Low should give you the best torque and hill climbing ability.
Do you feel any "Binding" in the steering wheel (difficult to turn)?
Remember a Jeep uses real driveshafts and differentials to give you 4WD - you cannot engage 4WD or 4-Low on dry hard surfaces. It needs a little bit of slip between the wheels for turns.
Check you're fluids too.

1987 Jeep YJ [Wrangler] so owner ship says''


Our Jeep Wrangler YJ's are equipped with a vacuum module on the front axle. It is used to engage the front axle when the transfercase is shifted into 4WD. Check the vacuum lines on the front axle to make sure they are connected. The passenger side axle shaft has a disconnect sleeve that is moved left and right by the vacuum.

91 wrangler 4 wheel will not engage


Check your fluid levels, you need to verify that the transfer case has fluid in it. Also, on one of my old jeeps the lever that put it into 4 wheel drive just stuck a litle. After yanking the **** out of it and moving it back and forth, drive a litle then stop and do it all over again.. a few times. it went into 4 wheel drive. this is why you are suposed to engage your 4 wheel drive once a month and drive around the block, just to make sure it gets flid where its supose to. if it doesn't get engaged then the fluid just sits at the bottum of the transfer case and doesn't get up on the gears.

Front wheel will not engage for 4 wheel drive


very possible. Put your jeep on 4 jackstands and put in 4 wheel drive. if the front drive shaft turns pull the vacuum disconnect and check the shift fork. They usually break before the shift actuator.
