Clunking noise coming from under the front of the truck

Need some help here. I have an 11’ 2500 4x4 lifted 5” just recently started hearing a clunking noise coming from under the truck while driving at highway speeds of +60 mph. If the speed is less than 60, no noise. Is sounds like it may be in the front axle. Checked steering, ball joints and transfer case shaft, everything is tight. Not sure what to do next. Any suggestions? I was thinking of opening the front axle and taking a look but it doesn’t make sense to me that the noise only comes at certain speeds. Thanks in advance.

if you get a vibration check the cardan joint. if it blows so does the transfer case. do you grease it?

Hi, thanks for your response. Sorry for the late response...been super busy. So, I replaced the ball joints on the driver side and thought that I solved the issue but the noise has actually gotten worse. It now does it as low as 45 mph. Thank you for the suggestion, I will check the cardan joint and let you know. Aslo, I will be pulling the diff cover to check the gears...
