i have a 2005 chevrolet extended cab Z-71 and it is all stock with a little bit more agressive tires than stock, with no lift. Well my problem is that whenever i come to stop at a stop sign, when i start to drive again there is like a pop or squeak noise that happens a couple times. i have checked the u joints and thats not it. it doesnt do it all the time either. just most of the time. any help would be greatly appreciative! thanks Kolton.
