i have a 98 tahoe 4x4 with the push button. the transfer case has a clicking/creeking noise coming from it. i jacked the back up and rotated the wheels to pin point that it is coming from inside the t case. any ideas what this is? the tahoe drives like a champ and i wanna catch it before it tears other stuff up. whatever the prob is. does any one have a exploded diagram of the t case
