I wounder if anyone had a similar problem. I have a Mazda6 2008 model, hatchback 5 doors. Recently the car is shaking while driving and no mechanic can tell me why. I have seen 5 different mechanics in the last 4 weeks or so. None could find what is causing the vibration (!!??) Replaced the following: 1. New brakes 2. Two new CV joints 3. Automatic gearbox service (gearbox specialist said the gearbox is fine) 4. New front wheel bearings 5. Three new engine mounts 6. New struts I am running out of options. Mechanics are useless, replacing parts and no solution in sight. Any advice would be appreciated.
