with all these new trucks that have the "knock" issues i was wondering if its somthing that everyone started hearing in early miles or coming later? i know the knock sounds my dads company truck is an 05 cummins and it has the knock. but a truck im looking at has 19k on it and i do not hear the knock, just wondering and hoping if this truck im looking at might be more than likely not going to get the knock...? i dont wanna have to deal with DC saying its not run hard enough just cause they dont wanna deal with it... thanks all
