Car shaking causes by speed: tire balance at highway speed, brake rotors when braking, CV axle on acceleration, engine misfire at idle. Diagnosis in Chico CA.
The most common cause of highway-speed vibration. A wheel that is even slightly out of balance causes noticeable shaking at 55-70 mph that may smooth out at other speeds. Tire balance from $80 for all four wheels.
If the car shakes specifically when applying the brakes, warped rotors are the primary suspect. The rotor surface is uneven, causing pulsation through the pedal and steering wheel during braking. Brake service per axle from $599.99.
A failing CV axle joint causes vibration specifically under acceleration, often with a clicking sound on turns. CV axle replacement from $350.
An engine misfiring on one or more cylinders causes rough running at idle and low speeds. Causes: worn spark plugs, failing ignition coil, fuel injector issue, or vacuum leak. Diagnostic and tune-up from $199.99/hr.
A failing wheel bearing causes a continuous hum or growl that changes with vehicle speed, often varying with steering input. Wheel bearing replacement from $531.89.
A bent wheel (curb strike, pothole damage) or separated tire tread causes vibration that remains consistent regardless of braking. Wheel inspection and replacement as needed.
Collapsed motor mounts transmit engine vibration into the cabin. Common at idle and low speeds, especially with AC on. Motor mount replacement from $350.
RWD and 4WD vehicles with worn driveshaft U-joints develop vibration at specific speeds, often with a clunk under acceleration or deceleration. Driveshaft service from $300.
