I have been having a weird vibration when i drive my car above 55 mph, so i had the tires balanced and checked the bushing on the car and every thing seems to be fine or so the mechanic claims. I did replace the inner tire rod on the driver side because the tire seemed to be a little lose but still the problem persists.Can any one help me

 

also forgot to mention that the driving wheel bounces left and right at low speeds
