Need help with a 2015 Freightliner dd15 harmonic vibration

Anything's possible. This sounds like one of those problems where it'll be at 10 different dealers and no one will find it. Stop at some backwoods hick shop for a minor repair and Cletus there will be like "you gots a brokun wire der on dat der thingynabob. I fixeud it and ur gud ta go"

 

It's possible, Martin bought a new star in 2011 (was a new 2009 that never sold) and had to get new injectors put in before it hit 100k.

Could be a faulty injector harness plug, bent pin in a harness, or a loose connection. Something could have not been set right in the top end, or came loose. Could be a bad lobe on the cam.

If I were you I would get it into a Detroit shop, not a Freightliner dealer. If you get thru the Des Moines area, get it into Interstate Detroit in Altoona. They are one of the best Detroit shops in the country.

 

just check if it has a dualmass flywheel as they can cause vibrations have you had someone rev it while you have the bonnet up does it vibrate at idle?

 

I have exact same problem and symptons from last 3 months. My mechanic leads me to injector but i have no codes. So iam still driving with vibration .its 2012 and 8k on it.
Do u fix the problem what was it?

 

Did u got fixed?what was the problem ,plz share..

 

I’ll bump this thread again because I got a 17 Freightliner Cascadia doing the same thing. I’ve finally decided it has to be engine/transmission related.

 

Any new updates with anyone im also having the same proble.

 

No. I’m the latest one that bumped this thread. Truck still does it. I’m gonna hopefully sell it soon anyway and let the next guy worry about it.
