What Causes the Steering Wheel to Become Hard to Turn?

[Josiah]

Steering wheel becomes hard to turn due to insufficient power steering fluid, low tire pressure, or malfunction of the steering gear or power steering pump. Insufficient power steering fluid: Power steering fluid is a medium oil used in the car's power steering pump, serving to transmit steering force and provide cushioning. The power steering fluid needs to be replaced regularly, and checked for leaks. When the fluid is insufficient, the steering will feel heavy and stiff. The power steering fluid should be replaced or replenished as soon as possible to ensure normal vehicle operation. Low tire pressure: Low tire pressure increases the contact area between the tire 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. Tire pressure should be checked frequently, and if the pressure is insufficient, it should be replenished promptly to ensure normal vehicle operation. Steering gear or power steering pump malfunction: The steering gear and power steering pump also affect the car's steering. Any malfunction in these two critical components can cause steering difficulties. Issues such as universal joints, chassis suspension stabilizer bars, or plain bearings should not be overlooked. Any problems detected should be repaired promptly.
