Why Is the Car Steering Wheel Heavy?

[Jan]

Here are the reasons why the steering wheel becomes heavy: 1. Insufficient power steering fluid/oil. Power steering fluid is a medium oil used in the car's power steering pump, which helps transmit steering force and provides cushioning. The power steering fluid needs to be replaced regularly, and checked for leaks. When the power steering fluid is insufficient, the steering wheel 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 higher friction and making steering more difficult, resulting in a heavy steering wheel, which is not conducive to driving safety. 3. Steering gear or power steering pump failure. The steering gear and power steering pump also affect the car's steering. Any failure in these two critical components can cause steering difficulties.

Last time I was driving, I noticed the steering wheel suddenly became very heavy, requiring a lot of effort to turn. This could be due to a potential failure in the power steering system, such as a broken power steering pump or insufficient hydraulic fluid, which naturally makes steering heavier without assistance. Low tire pressure can also increase resistance, making steering more laborious. Additionally, wear on the steering tie rods or rust on the chassis bearings can affect the ease of steering. It's essential to immediately check the hydraulic fluid level and top it up if it's low. At the same time, use a tire pressure gauge to ensure the tire pressure meets the specifications in the manual. Delaying repairs could lead to steering stiffness or even accidents. Safety comes first, so it's best to visit a repair shop early for a thorough inspection.
