1. Low power steering fluid. Check the fluid level in your power steering reservoir. If it's low, add more fluid.
2. Bad power steering pump. If the pump isn't working properly, it won't be able to provide the necessary pressure to assist with steering.
3. Worn power steering belt. The belt that drives the power steering pump can become worn over time. If it's too loose, it won't be able to provide enough power to the pump.
4. Faulty power steering rack. The rack is responsible for turning the wheels. If it's damaged, it can make steering difficult.
5. Tire pressure. Uneven or incorrectly inflated tires can make your steering feel hard. Make sure all of the tires on your vehicle are properly inflated to the recommended pressure.
6. Tire alignment. If the tires on your vehicle are out of alignment, they can pull the vehicle to one side, making it difficult to steer.
If you've checked all of these things and your power steering is still hard, you should take your vehicle to a mechanic. There could be a more serious problem that needs to be fixed.
