Vibration after 2.5" lift

I got Bilstein 5100s installed with clip at 2.5 up front, using the oem spring. The rear is set close with a block to level the truck. Now I have a vibration I can feel in the pedals and hear. The carrier bearing has been replaced and a spacer installed. Any ideas to the cause?

Thanks.

 

Does the noise/vib go away with 4WD engaged? If so might need the driver side cv needle bearing replaced with a solid bushing from ECGS.

 

I'll check that. Thanks

 

Did you ever get that figured out? Just put the same 5100’s on and I’m getting the same vibration

 

I did, it was the front diff needle bearing.
