BrokeDenali

So i went through what i could before it started to pour down rain. Nothing seemed wrong but was unable to check out everything. Its just a heavy clunk when i press the gas from a stop. If im really gently then it barely if at all does it. Im stumped but will keep updating.

Thank you mikebtte and jetmek. Im going to look it all over this weekend and whatever i find ill let you know. Oh no. Don't you worry. I will be back with a thousand more questions and my username will stay exactly the same. Thank you again for all the help. Will report back in a few days.

Yes yes ive looked before anyone comes at me. Im not a member yet bit i do need help. My yruck is a 2012 Sierra Denali 1500. It has 140k miles and ive noticed that only from a dead stop when i push the gas it clunks. It also feels like there is a delay to when the front wheels catch. Im not sure what it is and any suggestions would be appreciated. Thank you
