Looking for some help with front end vibration. I have a 2001 D2 with 107000 miles. The truck vibrates at 35 mph and above. I replaced the front shaft with a new shaft but still vibrates. I brought the new shaft to a local drive shaft shop to check balance and every thing was good. The truck does not vibrate with driveshaft removed and CDL locked. I now have chirp coming from the driveline? Could this be a bad front output shaft bearing? The flange has some play with shaft removed.
