When I can't see the car in front of me, that's my amateur opinion. Bring it to the shop where I can professionally diag it, and I'll give you my professional opinion.
I do most of the NVH concerns that come through our dealer and have never seen a CV axle cause a vibration. But not saying it isn't possible. And it wasn't a command, I forgot to put "i've" in my CV axle comment in the last post.
