So I've done some searching and see that vibrations are typical while it breaks in. However how long does it take to break in and does it go completely away? I installed it over the weekend and its been cool enough to not run the a/c around here. Well today I had to use the a/c and good lawd, at a stop it feels like the car is falling apart, its horrid. It honestly made me think the mount had just feel off. However if I turned he a/c off, it went back to just the "normal" amount of vibration. What's the typical break in mileage for this thing? If it doesn't get better Ill be going back to stock, no way I'm driving my family around in a brand new vehicle that now feels like a covered wagon rolling over rocks.
