What Are the Reasons for a Heavy Car Steering Wheel?

[StNora]

There are several reasons for a heavy car steering wheel: 1. Insufficient power steering fluid. Power steering fluid is a medium oil used in the car's power steering pump, which helps transmit steering force and provides cushioning. The fluid needs to be replaced regularly, and any leaks should be checked. When the power steering fluid is insufficient, the steering wheel may feel heavy or stiff. 2. Low tire pressure. Low tire pressure increases the contact area between the tires and the road surface, leading to greater friction and making steering more difficult, resulting in a heavy steering wheel, which is not conducive to driving safety. 3. Toe-in issues. Toe-in can also affect the car's steering. Toe-in helps the steering wheels automatically return to the correct position, ensuring stable straight-line driving. Problems in this area can also cause the steering wheel to feel heavy. 4. Steering gear or power steering pump failure. The steering gear and power steering pump are crucial components affecting the car's steering. Any malfunction in these parts can make steering difficult. Issues such as universal joints, chassis suspension stabilizer bars, or plain bearings should not be overlooked. 5. Overly tight bearing fit. If the rolling bearings or sliding bearings in the steering system are fitted too tightly, it can lead to poor lubrication and cause sticking or jamming.
