Why Is My Car Shaking While Driving?

Vibration and shaking can come from the engine, wheels, brakes, or suspension — and each source feels different. Identifying when and where the shake occurs narrows the cause before you replace the wrong components.

Engine-Related Shaking

• Misfire at idle — rough shaking that smooths slightly with RPM increase
• Worn engine mounts — vibration transfers to cabin, worse in drive at stop
• Dirty throttle body — unstable idle speed causing shake at traffic lights
• Failing idle air control valve — RPM fluctuation at idle

Wheel and Tyre Vibration

• Unbalanced wheels — shake at specific speeds, usually 60–100 km/h
• Tyre flat spots from sitting or hard braking
• Bent wheel rim from pothole impact — common on Faisalabad roads
• Mixed tyre brands or sizes causing uneven rotation

Brake-Related Shaking

Steering wheel shake when braking indicates warped brake discs or uneven pad deposits. The vibration appears only during braking, not during normal driving at the same speed.

Suspension and Drivetrain Shaking

• Worn CV joints — clicking and vibration during turns and acceleration
• Damaged driveshaft or U-joints — shake under load
• Worn wheel bearings — humming and vibration that increases with speed
• Loose suspension components — clunking plus vibration over bumps

Diagnosis and Repair

Mechanic Touch inspects the source of vibration systematically — engine scan for misfire codes, wheel balance check, brake disc inspection, and suspension assessment. Fixing the right system eliminates shake permanently.
