Got My Free Harmonic Balancer today. Cat ordered
 

Yesterday I heard a little engine noise and thought I had better get that recall done. Got on this site last nigh convertert and thougt maybe it is the intake manifold or a catalytic converter.

As I watched cable TV on their wide screen in a lazy boy I ate cookies and free coffee. An hour later I had my truck back with a free Harmonic Balancer. I was told it looked okay but it was in the number group that they replace regardless. In addition maybe I missed the cat recall letter.. They are way back ordered...could be months. But the price it right. Free. 6 years old $100,000+ miles and Mercedes is doing it free.
