My 05 Silverado has a very similar sound happening but ONLY when I let off the gas. While accelerating the noise does not appear. There’s don’t seem to be play in my u-joint but I guess it’s worth a shot to change it.

I didn’t have any play in mine either, let me know if it works out for ya 👍🏼

Super
