Shaking issue

Hello, when does the vibration occur? Is it accelerating? Cruising? Braking? If cruising or accelerating and not braking, ensure all wheels are properly balanced and no wheels are bent. Ensure the tires are good and not out of round. A good "road force" balancer can determine this information. If the wheels and tires are acceptable, you could have one or both of your axle shafts be out of round. This will require physical inspection with the vehicle in the air while in gear for a technician to inspect properly.
