Vibration and Noise Issue

[Supershafts]

Yup, that's what I was thinking. At least I got it figured out finally. Happy to have the car back on the road =P.

Detroit made there stuff just a little different then spicer...

The cap size is just a little different, width..

If you have a newer truck you'll see AAM is doing the same thing as detroit....makes me wonder if Detroit when it went under was swallowed up by AAM
