'14 charger vibration

Looks like you have two different make axles. One has a 6 ring boot the other is a 4 ring boot. Could have the wrong axle installed. Something is wrong there.
Right you are
I completely overlooked that

I had it in recently for a awd issue

I'll call the shop on Monday and see if they know what is going on, and if they were in there

With a little luck, they will replace them for me...but im not holding my breath
