So far it is not the (notchy) drive shafts (both) u-jounts. Now it is at a "specialist". At least I have a loaner '12 x.

 

SAME thing here. Hitting about 70-80 I noticed a vibration. Had the tires balanced and replaced the front rotors and brakes. I swear I still feel a very slight vibration and its driving me crazy. Was this issue fixed under warranty? I have 47K 2013 Journey

 

Mine was a driveshaft issue and was replaced. After it was replaced a slight vibration existed but is normal from the 3 others I have driven with 30 -80k miles on them. It is now now not noticeable for me. I guess I am getting used to it.

 

you wouldn't happen to be running wheel spacers would you?

 

Nadda, even traded wheels/tires first to see if it went away.

 

Never mind forgot the 2010 has a different grill
