I just replaced my center line bearing on my 2004 Chevy Silverado. During the installation the marks I've made on the driveline rubbed off. And I'm sure I did not get it lined up correctly. Now I have very heavy vibration. Is there any way to get back lined up correctly? Are there any markings or anything on the driveline that can help me get it lined up correctly?

 

For what it's worth, pull the drive shaft, and reinstall 180 deg. Give that a try.

 

I'm going to try that right now. Thank you for responding

 

If that doesn’t work you can balance it using hose clamps - it takes some patience and trial and error but it works well.
