Poll: Does your '03 Cummins have the "vibration"

I know DC watches this board. It sure would be nice if they chimed in

Interestingly, there is some discussion of an RPM range drone on '04 PSDs on dieselstop.com. The assertion is that it's the turbo mounting bracket. Not a lot of details, but you can scan this thread to read about it.

I think I have found the culprit. Has anybody raised engine rpm under the hood to listen for the hum or feel the vibration? Mine is definitely coming from what appears to be the fuel system lift pump. I took a mechanics stethoscope and it seems to be the place of orig. Almost sound like possible pump cavitation, Just my two cents. If I keep this truck It must be fixed. It will drive you CRAZY!! Thanks 034me

I'v called the DC customer center(800-992-1997) to try to resolve my vibration problem after my dealer gave up. The customer center said they have not heard of this problem:--) ( I had him do a search) So now i waiting for the district Rep. to take a drive with me, So far the two dealerships i have taken it too, do feel the vibration, ( running the A/C makes it worse) but no one will put it in writing,They say it's a normal vibration. You can bet, when me and the Rep go for a test drive and he doesn't admit to feeling the vibration, One of us will have a long walk back, and it's "not" going to be me. However it has been a great truck!!!

Check your truck for the vibrations from the fuel lines and see if you think this might be the same result as mine, Thanks
