I had a problem couldn't figure out vibration under load and didn't get any codes to pop up. Did Injector test and the technician in lincoln ne kenworth said 2 injectors were a little off and said he wouldn't change them but i told to go ahead and just do it. after changed injectors vibration was gone and truck ran really smooth with no problem after.

Also had a clutch problem. put in a new clutch and after a month started having and constant vibration,and when I would take of the clutch would really grabb and jerk my truck, after checking drive line and yokes (motor mounts/ changed them) tranny went out. when they took the tranny out my clutch was shattered around the center hole. after new clutch and tranny no more vibration.
W903B Thanks this. -
Yah ive ran cut out tests and I think the injectors being out a little bit are the cause of my vibration. Not going to change them yet as they are within spec, I will continue to monitor them until its time to replace.

I also had straight pipes with the quiet inserts, when I pulled the pipes off the baffles were completely plugged with soot. I put on a new set of straight pipes and the truck seems to be much much happier.

Sorry I never did find what was causing the problem, the truck has been gone for almost a year.
