I have a 2500 4X4, '04. 5. I love this truck!!! I had a 3" lift, 35X12. 50 18's put on it and it seems to wander to the right a little. Last night I was reading issue 45 and saw a silmular problem on page 18. This guy ended up changing the Idler Arm and it corrected his problem. I looked up the part number and it only went up to '99. Is there a solution for an '04 out there?
