As the car is driving there is a sound like something isn't secured properly and is knocking as the weight moves around the car during turns or going over bumps.
When driving and accelerating along a stretch of road the car seems to vibrate or feel like there's something wobbling. It can sometimes make the car feel unstable when cornering.
When driving the car feels like it's vibrating, the sensation can be felt through the steering wheel but may also just be a general vibration noise inside the car.
