1. Loose or damaged engine mount: This can cause the engine to vibrate excessively when it is under load, such as when you are turning left.
2. Driveline issues: Such as a worn or damaged driveshaft, or a faulty CV joint, can also cause vibrations when turning.
3. Wheel alignment: If your wheels are out of alignment, it can cause the steering wheel to vibrate when you turn.
4. Tire issues: Such as a flat tire or a tire with a damaged sidewall, can also cause vibrations when driving.
It is important to have the issue diagnosed by a qualified mechanic as soon as possible to prevent further damage to your vehicle.
