I have a 99 jeep and if I put it in 4wd drive it makes a poping nose and the 4wd light stays on always and it’s a stick shift with the 4 cylinder.motor and I don’t know if the actuator is bad
 
You will need to put the Jeep up on a lift, engage 4x4 and listen for the noise. I believe the noise may be the transfercase chain jumping on the sprocket due to a stretched chain, but you won't know for sure until you can climb under the Jeep to locate the noise.

Do u know how hard it is to change that chain and the sprockets
And I have to pull the transfer case out don’t I
Slow down bud..dont buy anything yet..as stated you need to diagnose where the noise is coming from..you have relatives/friends that can help you? Have them listen while you try and replicate the noise and try to pinpoint it
 
Yes the nose is coming from the back of the transfer case and I can put it in 4 high and it does it if there’s any gas given to it
