My 4WD is making a grinding noise. Any ideas?

Hi, I noticed this grinding sound coming from the front part of my Cherokee after i put it into 4WD.

I have looked under the front end as much as i could with out removing anything. and everything looks fine. no rubbing of the drive shaft or tires. the CV joints look fine. I don't know what it could be. maybe it's something inside the front dif, or t-case? and this sound only happens when in 4WD. It also gets worse and effects the steering when i turn the wheel while moving forward.

Has anyone else had this problem?
Does anyone having any ideas what it could be, so i don't have to just start pulling my whole front end apart blindly.

Anything helps thanks.

See other thread - is this happening when you drive it on the street or when you drive it in the dirt? You should never use your 4wd when on the street. If you do, binding and weird noises are to be expected and are completely normal.

check the linkage mechanism bs under there, mine likes to pop out if i try to put it in 4lo and i will get trapped inbetween 4hi and N.

Also the weirdo is incorrect, you CAN drive it on the pavement, but not if its dry, Low traction situations like snow and ice ONLY and like gravel.

Start by jacking up the front end and spinning the wheels and drive shaft by hand. Listen for noises (other than brake drag), and narrow it down from there.

88 grinding

my jeep 88 cherokee is doing something similar. every time i give it to much gas from a dead stop i hear grinding coming from underneath. its just from a dead stop and only in the first gear and it again it only happens when i floor it or rev it to high then after it shifts up its fine. it started after i was testing out the 4x4 low. when i shifted down to low it wouldn't connect right and only really connected if i held the lever all the way back and drove for a bit. if anyone could give me some more information on it that would be great and i really hope its not the tranny. also the fluids are all at good levels i just checked them last night.
