thanks for the input guys. Yeah, i tightened the yoke, and got rid of the growling noise. However, when I punch it, it is still bogging down and getting a knocking noise under my feet, then i let off a little and then the truck wants to get up and go. I'm thinking about getting a new rear end. If i wait too long before i get a new one will it cause any other damage? Maybe to the front end anywhere? Because that is where the knocking noise is coming from.
