1. Check the tie rods. The tie rods connect the steering rack to the wheels. If the tie rods are loose or worn, they can cause a clunking noise when you turn the wheel.
2. Check the ball joints. The ball joints connect the control arms to the steering knuckles. If the ball joints are worn, they can also cause a clunking noise when you turn the wheel.
3. Check the power steering fluid. If the power steering fluid is low, it can cause the power steering pump to cavitate, which can make a clunking noise.
4. Check the steering rack. If the steering rack is damaged or worn, it can also cause a clunking noise when you turn the wheel.
If you are not sure what is causing the clunking noise, it is best to take your car to a mechanic for diagnosis.
