need help with 4 wheel drive gears

so today i went wheeling and it was a good day i was switching back and forth form 2 wheel to 4w high (its an automatic jeep btw) depending on the trail conditions. then when i went to put it in 4w low it made a horrible grinding sound. then it wouldnt let me put it in park or drive only in neutral would it not grind. so i turned the car off and sat there for a moment. and restarting my jeep in netural i was able to put it back in 2 wheel and then i left to go home when i got out of the mountains. i let the gears cool down for about an houror so. i then restarted it put it in 4w hi and it seemed to work fine. does anyone know what happend or can the help me

oh then after what i would call a good day i ran over a nail on the way home and put a whole in my tires FML

I can answer that for you when you shifted between ranges the transmission was freewheeling hense the grinding in the transfer case and when you shifted to park the transmission was freewheeling hence the grinding of the park pin/shuting it off allowed you to put the transfer case in gear so when you restarted no grinding /your on your own forthe nail lol!

after reading your original post thought it might be shifting technique however now not sure if that or a case problem/have you since put it in low range and freewheeling means stuff inside is turning without moving the vehicle

I think it was shifting technique as well. The official video says to pull firmly into 4lo from 4hi (going straight through N) without pause, while moving slightly. A small amount of grind is normal. Mine is a 5 speed transmission and I can usually get my t-case in 4lo without grinding. But not every time. How new are you to shifting it into 4x4?

im not so new at it like i use it from time to time in snow in colorado but not to much. i think you found my problem tho. when i was wheeling my passenger asked why there was an "N" and i said its for neutral and hes like why? you have neutral on your gear shifter and i say idk so i tryed to put it in "n" we decided it means NEVER not Neutral. so i guess i will just have to wait and see how messed they are
thank you

Are you driving when you pull it back into 4lo?

2 to 3 mph rolling MAX. And yes,,,pull straight from 4hi to 4lo.

If you don't want it to grind....Stop, slap the trans in N,,,and yank back.

I'm not familiar with automatic transmission into 4x4, but mine grinds putting it into 4lo also. I don't think you need new gears, but I'm not sure how the transmission determines weather it can go into gear or not...
Also you might get more help if you posted this in the model tech forums.
