i added washers to the heat shield because it was show some signs of cracking and was a fix someone had in the same model of truck. I would like to know where to start looking. I suspect it could be inside the catalytic converter but I don't want to just start changing parts because I do not have the money. I have ruled out many things like bearings and u-joints. ( I hope)
Will I be charged for these replies or just charged for when you have an answer or solution?
