Why Does My Car Shake When I Drive

A car that shakes while driving is telling you something is out of balance, worn, or damaged in the wheels or drivetrain.

Shaking while driving is most commonly caused by out-of-balance tires or wheels. If the vibration starts around 55-65 mph and gets worse with speed, unbalanced tires are the most likely culprit. A bent wheel, separated tire belt (creating a bulge), or a tire with flat spots from sitting too long can also produce vibration at speed. These issues are felt most through the steering wheel if the front wheels are affected, or through the seat if it's the rear.

If the shaking happens at all speeds, the problem may be deeper — worn tie rod ends, ball joints, or wheel bearings allow play in the wheel assembly that creates vibration. A warped brake rotor causes shaking specifically when braking. On AWD or 4WD vehicles, a worn CV joint or U-joint in the driveshaft can produce vibration that changes with speed and load.

Driving with vibration accelerates wear on tires, suspension, and steering components. Ez Mobile Mechanic inspects your wheels, tires, and suspension at your Jacksonville location to find the source.
