12.7 Series 60- Issues after rebuild

Anytime! Sounds like you need it.

 

Could it be just an idle vibration from injectors needing calibration? Maybe Driveshaft is off 180 degrees? Sometimes causes vibration while driving? Maybe a flat spot on a tire? If so, may go away. I used a noise app on mine, and came up with 76-80 decibels inside the cab while running down the road.

 

The yoke they pulled off the splines to replace your carrier bearing might be out of phase. The welded ends of your drive shafts need to be lined up. When pulling that yoke of the shaft you're supposed to mark it and put it back on the same splines. That's what I'd look at first. Somebody doing shoddy work got it out of phase on my truck a few years ago when replacing the carrier bearing. I didnt even know about drive shafts being in phase until somebody mentioned it to me and explained. I only recently found and fixed it, the truck rides like new again. The shaft on the right in the pic below, after I got it out of the truck before pulling it apart to put a new carrier bearing on. You can see in the photo clearly it's waaay out of phase.

 

His vibration is at idle I think. Wouldn't be in the driveline if that's the case since it's not turning and sitting still.

 

It doesn't change with engine RPM's ????? It stays constant no what what your speed is also ?

 

Whose injectors? Reman or rebuilt. Lots of junk out there. Those Bosch cores are getting pretty old.

 

Take pictures.
