Amckinney

I have a 1999 Silverado 1500 with the 5.3 and typically I’m having a very subtle but noticeable clicking from 10-15 mph. I was thinking cv axles do I removed them and no change. However I removed the front driveshaft and the noise is completely gone! The joints on the shaft are good so I’m not sure whether it’s the T-case or the front differential. Has anyone else come across this issue? It’s driving me nuts!!
