I'm looking into getting a 2007 silverado nnbs. i test drove a truck that i really like and hopfully the deal will come thru. when i drove the truck i noticed a clunk or pop noise when you come to a stop or take off. It's kinda hard to explain but guessing it could be a differential, suspension, or the slip yoke in the tranny binding up, but i have no clue so asking if any of you have this problem, or heard of this? its 2wd if it helps any. I have a buddy with same clunk noise in his truck and he bought his new hasent given him problems but dont feel or sound right but could just be me.
