What are the reasons for difficulty in turning the car steering wheel?

[Everett]

Reasons for difficulty in turning the car steering wheel: 1. Insufficient power steering fluid, which is a medium oil used in the car's power steering pump to transmit steering force and provide cushioning. The power steering fluid needs to be replaced regularly, and checked for leaks. When the power steering fluid is insufficient, the steering will feel heavy; 2. Low tire pressure increases the contact area between the tire and the road surface, leading to greater friction and making it harder to turn, resulting in a heavy steering wheel that is not conducive to driving; 3. The steering gear and power steering pump also affect the car's steering. Any malfunction in these two key components can cause difficulty in steering; 4. If the rolling bearings and sliding bearings connected to the steering system are too tightly fitted, it can lead to poor lubrication of the bearings, causing sticking phenomena.
