Why does the steering wheel shake when you turn it to left?

Several reasons might cause a steering wheel to shake when you turn it to the left. Here are some common causes:

Wheel Alignment Issues: Improper wheel alignment, often caused by hitting curbs or potholes, can lead to uneven tire wear and shaking when turning.

Worn Steering and Suspension Components: Worn-out components such as ball joints, tie rods, or steering rack can result in vibration during turns.

Damaged or Loose Steering Rack: A faulty steering rack or loose bolts in the steering system can cause the steering wheel to shake.

Uneven Tire Wear: Uneven wear patterns, flat spots, or damaged tire belts can create a shaking sensation when turning.

Tire Pressure Problems: Incorrect tire pressure or a difference in pressure between the left and right tires can lead to shaking.

Driveline Problems: Issues with the driveshaft, universal joints, or axles can sometimes cause vibrations in the steering wheel.

Brake Issues: If the brake rotors are warped or there are issues with the brake calipers or pads, it might result in a shaking sensation in the steering wheel when braking or turning.

To determine the exact cause, it's recommended to seek inspection by a professional mechanic who can identify and fix the underlying problem, ensuring safe and smooth steering.
