Why is the steering wheel heavy?
2 Answers
Reasons for a heavy steering wheel: 1. Dirty power steering fluid. This situation is similar to how dirty engine oil affects engine power and performance. Dirty power steering fluid can cause the steering wheel to become increasingly heavy, and a lack of power steering fluid can also make the steering wheel feel heavier. 2. If it is electric power steering, check whether the fuse is burnt out, or if there is an open circuit or a short to ground in the wiring. Repeatedly turning the steering wheel while stationary or at low speeds places a heavy load on the power steering system, which can easily cause the steering gear to overheat and enter a protective mode, resulting in heavy steering. It will return to normal after cooling down, which is a normal phenomenon.
I've encountered many common causes of heavy steering. If the power steering system malfunctions, such as a faulty electric or hydraulic power steering pump, low or leaking fluid, steering becomes particularly strenuous; low tire pressure is also a key factor, as insufficient pressure reduces grip, naturally making the steering wheel heavier. Additionally, worn or stuck bearings in the steering column or steering wheel connection, or faults in the front suspension system like loose ball joints, can increase steering effort. I recommend first checking tire pressure and power steering fluid levels yourself. If tire pressure is too low, inflate them promptly, and if power steering fluid is low, try topping it up. If there's no improvement, head to a repair shop immediately, as unresponsive steering affects driving safety, especially during high-speed turns where control can be easily lost.
