Is Heavy Steering Caused by Power Steering Pump or Steering Gear Failure?
1 Answers
Heavy steering wheel in a car can be caused by the following reasons: 1. Insufficient power steering fluid: Power steering fluid is a medium oil used in the car's power steering pump, which transmits steering force and provides cushioning. The power steering fluid needs to be replaced regularly, and any leakage should be checked. When the power steering fluid is insufficient, the steering will 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 difficulty in steering, resulting in a heavy steering wheel, which is not conducive to driving safety. 3. Toe-in: Toe-in also affects the car's steering. Toe-in ensures that the steering wheels automatically return to the center, maintaining stable straight-line driving. Therefore, issues in this aspect can also cause heavy steering. 4. Steering gear or power steering pump failure: The steering gear and power steering pump are also critical components affecting the car's steering. Any failure in these two important parts can lead to difficulty in steering. Issues such as universal joints, chassis suspension stabilizer bars, or plain bearings should not be overlooked.
