Grinding noise in 4-Lo only when put in gear?

Hey guys, I have a 96 GC with a 5.2 and the 249 transfer case, when I shift it in 4lo the light comes on and everything goes into place, but when I put it back in Drive or reverse from neutral, there's a really bad grinding noise but only in gear, when you put it back in neutral it goes away, does this mean the transfer case is toast or? Ive tried putting it in 4lo at a slow roll in neutral and also with the jeep off. THANKS!

Your linkage needs to be adjusted. trying doing it while rolling in neutral at 3-5 MPH, and throwing it into 4lo then. Then you can put it back in Drive.

Edit I see you tried that already, Get underneath, and adjust the linkage. read up on it as im not 100% of the correct way.

Ok I will try adjusting the linkage tomorrow...could it be doing that if even the front diff. or the transfer case itself just doesn't have enough/right type of fluid?

The grinding noise means the t-case is not really in low, so the linkage may need to be adjusted to make sure it actually goes all the way in. When I shift mine I put the auto trans in neutral, stop shut off the motor and then shift .... This was advised by a New venture gear service rep and as long as it goes all the way into low it will not grind this way.

U can check fluid level to make sure it's topped up. That'll help a little getting it in

+1 on checking the linkage. While you're under the vehicle, take a flashlight with you and inspect the transmission and motor mounts too.

While checking the linkage, have someone in the Jeep move the tc lever and watch the pivot points of the linkage to see if the bushings at the body or transmission are worn out or missing. Unless it slipped, the adjustment rarely needs to be touched. When I had the 249 tc years ago, I shifted it direct from 4hi to 4lo while slowly rolling with the tranny in neutral. It was a firm movement and went in everytime.

the t-case is probably like half in and half out of gear because the linkage needs adjusted
