What Causes the Steering Wheel to Feel Heavier?

[OAxel]

There are several reasons why a car's steering wheel may feel heavier: 1. Insufficient power steering fluid. Power steering fluid is a medium oil used in the car's power steering pump to transmit steering force and provide cushioning. It needs to be replaced regularly, and any leaks should be checked. When the power steering fluid is insufficient, the steering wheel may feel heavy and 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. Malfunction of the steering gear or power steering pump. The steering gear and power steering pump are also critical 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 too tightly fitted, it can lead to poor lubrication and cause sticking or resistance.
