Cannot figure out vubration

[jsonadam]

I am new to this forum and hoping someone may be able to help with my Fusion Hybrid issues. I have had a vibration in my 2012 Fusion Hybrid for the past year. We cannot figure out what is the cause. I would appreciate any suggestions or feedback. Luckily, I have a good friend that is the GM of a Chevy Dealership so a lot of the exploration of the issue was done at no cost. We are at a point now where they are out of ideas. I am going to take it to Ford but figured out what it may be. So far we have done the following things. Each time we did something below, the vibration got better and was eliminated at certain speeds. Now the vibration starts around 35. It is at its worst around 45 – 55. It feels like it is coming from the rear as I feel the vibration more in the seats and not in the steering wheel. I am giving this car to my daughter in a few months and I want to figure this out before I give it to her as it is annoying and I want to make sure it is safe for her to drive.

 

Replaced tires

Balanced tires (Several times)

Road Force Balanced tires

Replaced 2 rims – one was severely bent, the other was barely bent

Cheeked suspension and cv/ball joints

Replaced brakes

Replaced tires and wheels with another set from a same year, similar model Fusion (not hybrid) – vibration remained

A severely bent rim suggests impact with a curb or other object. Was it in an accident? That impact may have affect other suspension components or possibly the unibody frame. I did not see alignment check on your list.

try balancing tires with airsoft 20g pellets, any vibration that has to do with moving tires/rotors etc will automatically be balanced look at the video >

Which position was the bent rim in? I agree sounds like there's some collateral damage. While tires/wheels are the source of most vibration, it's up to the suspension and bushings to dampen them out. If you've got a bad bushing or bent suspension link, it can magnify even the smallest tire imbalance.
