2000 Wrangler-2WD stops working..

Driving along, stop at a light, put in 1st gear, nothing. Jeep is still running.
2nd gear-nothing. However, when I put in 4WD it engages and I can drive it.

This Jeep has not been in 4wd since Feb 2012, until just this last weekend where
it went mudding for the first time.
Has new engine 30k miles on it.

Anybody have any thoughts?? New Jeep owner.

Have you gotten under and checked your transfer case linkage? Tjs have a wonky z linkage that can pop out and make the tcase not shift correctly

I had this problem keeping it in 4low. But how does the transfer case jump to neutral out of 2wd and miss 4hi???

Do you have a body lift? If so the linkage may not be adjusted properly.

If a previous owner had a body lift, adjusted the linkage and then removed the body lift that could cause issues too

This. I don't know how the transfer case could slip out of 2WD, past 4 Hi, and into neutral.

I was wondering the same thing.... In 2WD have a friend check to see if the rear drive shaft is turning or not when in gear and trying to move forward.... When it 4hi or 4lo you are most likely being pulled around by the front axle only which is why you were able to move.

Update, While driving to shop--brakes pretty much went out. So pulled over, totally out of fluid--which was full last weekend. Looks as if back Axle is coming off.
So my question is now..if Axle is out (broken?) is this something that can happen daily driving? It is 13 yrs old, but we stayed on top of repairs when needed. OR is it more likely to be a 4 wheeling issue? We never took it mudding--just knew we couldn't afford to break it. But our friends 18 yr old took it mudding just the other day. Not trying to place blame--just curious what you all think.

The linkage might have popped out of the stupid bracket thats in the tub, and threw off what appears to be the normal shift pattern, when the shifter appears to be in 2wd, the tcase might actually be in neutral, when shifting it into 4wd its possible that the tcase is actually being shifted into 4hi.. remember, tjs have stupid z linkage..

There aren't too many other problems it could be, default 2wd, power passes through the tcase to the rear output only. So either hes not actually in 2wd, theres no rear driveshaft, or a rear axle broke

Yeah that can happen daily driving or wheeling. The stock rear axles are weak pieces of crap.

Just to clearify...We owned Jeep until a week ago---sold to friends son...then BAM! No lift, had bigger tires for awhile then back to stock size for fuel reasons. Again no off roading or rough driving. New engine 30k ago. Rear diff had a broken seal less than a year ago..fixed asap. Trying not to leave them hanging out to dry on the purchase but also knowing we had no issues that were not resolved by same mechanic for over 6 yrs.

Well if they took it mudding, then that's their fault for breaking it. A rear axle shaft only exists in one of two conditions, not broken, and broken. The rear axle is a c clip design, if the axle was broken before the sale, you'd have no power to the rear with an open or even limited slip differential, and eventually the shaft would come out with the wheel after being driven on, as it's doing now.

On another note, How did the broken shaft make the brake system empty its fluid? I can see it doing that if it were a disk setup but how does this happen with drums?

Probably unrelated to the shaft breaking, but without seeing it in person it's difficult to say

If the broken shaft let the drum walk off the brake shoes far enough for them to extend past the limit of the cup seals in the wheel cylinder, you will have a big leak every time you step on the brakes.

I was thinking that it had to do with that but didn't know if the brake shoes would let the wheel cylinder push them far enough to do that.

You are all a HUGE help--Thanks so much. I will let you know what turns out in case you are curious folk! lol I know I am. I am just the type of person that I feel not responsible, but horrible that it happened a week into buy from me you know. They know I would never have sold them something broken or in need of repair unless I stated such to a friend or stranger. Thanks again--and I shall return with what they had to do to fix the ole girl.
