Question about 1991 Jeep Wrangler
Need some help to point me in the right direction.
Totally stock Sahara, 4L motor, 5 speed manual tranny, 180K miles.
My Sahara won't engage 2WD!... My wife was driving along and clunk! The normal 2 wheel drive stopped working. It was making a kind or "rattleing sound" when decelerating in gear, like slowing for a stop light.
I went to the rescue, and she was right... when you put it into gear in 2WD it don't go!... it's like the transfer case is in Neutral.
BUT, if you switch it into 4WD Lo or 4WD Hi, the car will drive just fine.
I appreciate your help!
O yea, and my Chilton's wasn't much help.
Check to see if front drive shaft is locked in by spinning it by hand, if it is there is a sensor on top of the tranfer case that has the vac lines connected to it. On the bottom of the sensor there is a ball. If the ball gets stuck open the vac stays on and the front end stays engaged no matter if your in 2 or 4. The sensor is like 22 dollars from chrysler.

It sounds like your driveline to the rear wheels is broken. Could be transfer case output shaft to the rear wheels has broken. Try disconnecting the rear drive shaft and see if you can turn it by hand with the transfer case engaged in 2WD. If you can turn it while the Sahara is in gear, the output shaft is no longer connected to the engine for some reason.
