I had that problem to. count the number of "clicks" when putting it into different gears. make sure that the shifter does not go side to side while driving...that can cause damage. its an older truck things let go. i have to re-do the seals on my transfer case cause i was driving my jeep inbetween 2H and N and she got hot and poped them.

Different 4wd settings


you should have 2 hi 4 low 4 hi and nuetral on your transfer case 4 hi would be anything up to 35-40mph or lower 4 low is almost never used it just gears down your t case if your climbing a hill or super stuck the manual locing hubs are extremely reliable do not have them locked on dry pavement or concrete just loose dirt snow ice ect put the tranny gear shifter in nuetral to put your t case in 4 low

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


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.

Can't transfer to 4L or neutral mode


Transfer cases can be quirky. I've got a 91 Wrangler, an 86 Cherokee and a 75 Blazer. When I go from 2WD to 4WD, they each have their own personality.

There are a number of things I've learned to persuade a stubborn xfer case to shift.

Try mixing these :
  • Engine running, vehicle not moving
  • Engine off, Shift Xfer case, Restart
  • Tranny in neutral
  • Shift Xfer case 'N', Tranny in gear, Tranny in neutral, Xfer case to 4HI or 4LOW (as long as you feel it register), Tranny in gear, try to move
  • Shift Tranny to Reverse, roll a few yards
  • Lock/Unlock the Hubs
To get back to 2WD:
  • Drive for a few feet in a straight line
  • Unlock the hubs
  • Tranny Neutral
  • Shift xfer case
Let me know how it turns out.

Jeep 4wd auto trans


Place the trans in nuetral then put the transfer case in 2HI.
