Dang not saying there is an issue but thats weird one cant say ive ran acrossed one like that might just be normal all my chevys make some noise but do notice the new ones make a little more noise
Scott does your truck have the auto option on your 4X4 option???? because if it does and you leave it in auto you just blew out your locker in your front axle its warrantied if your still covered pass it along only use auto 4X4 in wet conditions i know this becaue i work at a gm dealer and we have to fix it all the time people dont listen.
i work at a gm dealership and yes there are issues with the steering, the gears to be specific so i feel your frustration those dealers should be hadling it better.
