I own a 2002 1500 HD. I bought the truck used and have had so many problems with it. I have already put a new transmission in it and now have a constant knocking noise coming from the motor. I can not seem to figure it out. I have gotten the run around that it has something to do with the piston slapping to I need a new motor. I only have 69000 miles. I am new to this site and would greatly appreciate any feedback.
