What Are the Reasons for Difficulty in Turning the Car Steering Wheel?
2 Answers
There are several reasons why a car's steering wheel may be difficult to turn: 1. 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 fluid needs to be replaced regularly, and when it is insufficient, the steering will feel heavy. 2. Low tire pressure. Low tire pressure increases the contact area between the tires and the road surface, leading to greater friction and making turning more difficult, resulting in a heavy steering wheel that is not conducive to driving. 3. Malfunction of the steering gear or power steering pump. The steering gear and power steering pump are crucial components affecting car steering; any issues with these parts can cause steering difficulties. Problems such as universal joint issues, chassis suspension stabilizer bar problems, or plane bearing issues should not be overlooked. 4. Overly tight bearing fit. If the rolling bearings and sliding bearings connected to the steering system are too tightly fitted, it can lead to poor lubrication of the bearings, causing jamming. It is advisable to conduct targeted checks on the mechanical parts and the power steering system, or to inspect for any leaks, air intake, or damage to sealing components.
I haven't been driving for long, but it's really frustrating when the steering wheel suddenly becomes heavy. I remember that trip to the countryside—turning the wheel felt like pulling a boulder. A friend suggested it might be an issue with the power steering system, like low hydraulic fluid or an aging pump. Low tire pressure can also cause this, increasing friction and making steering harder. When I got home, I checked with a tire pressure gauge and found the right front tire was only at 15 psi, over 20 below the standard. After inflating it, steering became much easier. If it's not the tire pressure, you should also check if the steering column bearings are rusted or if there's an electrical fault. For electric vehicles, the electric power assist motor might be faulty. This issue shouldn't be ignored—driving long distances with it can be exhausting and dangerous. It's safest to get it checked at a professional shop. Don't skimp on safety; it's always the top priority.
