Looking for some advice. I have 2001 d2 with 107000 miles. The truck vibrates. I have replaced the driveshaft with new and still have the vibration. I also rebalanced the new shaft but it still vibrates. The truck doesn't vibrate with the shaft removed and cdl locked. I also can hear a slight chirping noise. Could this be the front output bearing? There is some play there with the shaft removed?

 

new as in oem style shaft or upgraded so you can grease it every oil change? Sure sounds like a problem shaft.

 

The shaft is new with grease fittings. This is the second new shaft shaft that I tried. I had the balance checked at a local shop. I believe I could hear some noise with shaft removed at highway speeds?

 

ahha... I'm going through the same thing right now... What speeds does your truck vibrate with the shaft installed?

 

Vibrates 35 mph and up. If I pull the front shaft it's nice and smooth.

 

For me it's 60 and up. I have tried different front shafts, it's not the shaft.
