I have a 2004 2500hd d/a and rencently theres been this loud horrible popping noise only in 4 hi right underneath my feet on the drivers side only. This happens whether im going straight or turning left or right. When pushing heavy snow its get worse and worse where the truck wont even push the snow anymore if it gets too heavy, not from a loss of traction, but that the popping noise gets really bad like something is grinding and slipping on the transfer case. When it started doing this i was running my programmer on a 110 tune, accidently, and i feel that it destroyed the transfer case. Also not sure if it could be a bad cv joint but theres no tears in the boots and it doesnt seem that far up front on the truck. Also could this be from a bad or broken u joint, it seems way too loud and harsh for it to be a u joint but im not sure. thanks for any help. p.s. this noise/popping happens at mostly lower speeds, like from stop and when hitting the gas at lower speeds.

Tranfer case chain is loose and slipping around the cogs.

This is my first thought also may want to check out the ftont shaft first take it out and look it over real good could be there as well.
Should br fairly qick to see what is happening. if not in the front shaft drain the t case and check for pieces of metal coming out of it
