Thanks for posting that video - first time I've seen it! :happyyes:Welcome to the forum!!! Before going and taking your jeep to the shop or tearing apart your transfer case make sure you are putting 4L into gear the proper way, There is a proper way to shift your jeep into 4L and if not done properly the sound it produces is not pretty, check out the link to a mopar jeep owners tips video , skip the video to about the 40:40 mark, follow the instructions as stated on the video, if tor still having an issue after a few tries, might want to being it in to the shop..Let us know if that fixes the problem... Good luck!!
