Shaking real bad faster you go worse it gets

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! When your Mazda 3 feels like it’s auditioning for a "Shake, Rattle, and Roll" cover band, it’s usually a wheel, tire, or suspension issue. The fact that it gets worse with speed screams tire imbalance or a bent rim. Start with a visual check: look for uneven tire wear, bulges, or damage to the rims. If everything looks okay, have your tires balanced and checked for alignment. It’s also worth making sure the lug nuts are torqued correctly—loose ones can make your car feel like it’s falling apart. If it’s not the tires or wheels, consider suspension or drivetrain culprits like a bad CV axle, wheel bearing, or even a warped brake rotor. Ignoring it could lead to bigger (and pricier) repairs, so get it inspected ASAP before it goes from shaky to downright dangerous.
