I was driving my 99 Grand Cherokee limited in 4Lo then it just popped out of 4Lo into neutral and will not re engage! When i put it into 4Lo it just revs and grinds when i step on the gas and truck wont move? but it works fine on 4 All-Time? what could be the problem?? can it be repaired or do i need to replace the whole transfer case?

just tried it and it still grinds. It stays in 4Lo but as soon as i press the gas then it just grinds, kinda sounds like a bicycle with a card placed on the back wheels that makes a loud tapping noise lol and the more gas i press the louder the sound. Once the gas is press it still grinds as i put it into neutral and also going from 4Lo to Neutral but in 4All-Time its fine again.

I even started the truck in 4 Lo and its fine until i press the gas, so is that a linkage? or something else? just tried it and it still grinds.

I'm going to stick with linkage. Those transfer cases (I think you have an NV225?) are damn near indestructable. Try pulling the handle for the transfer case up a little beyond 4-lo and see if you can get it to engage. Like I said earlier, EVERY ONE of the automatic Jeeps I've ever owned, and there have been many, has been a royal pain to get into 4-lo, and even harder to KEEP in 4-lo.

i think mine is a NV247. My Jeep is a 1999 Grand Cherokee Limited V8 quadra-trac 2.

Any advice on how that linkage can be fixed? if i were to bring it to a mechanic just for the labor what part would i need to buy to repair the transfer case linkage? thx i think mine is a NV247.

I don't think you'll need to buy ANY parts. I believe it's just a matter of ADJUSTING the linkage so that when you throw the shifter it fully engages the 4-lo gear in the TC.
