Why is the car steering wheel heavy?

[StCharles]

Reasons for a heavy car steering wheel: 1. Dirty power steering fluid, generally after driving for 2 to 3 years, if the steering wheel becomes heavy, the fluid needs to be replaced; 2. Leakage of power steering fluid, resulting in reduced fluid levels; 3. Excessive tightness in the bearings between steering components, overly tight adjustment of the steering tie rod ball joints, or bending of the steering shaft and sleeve causing jamming. Cars are equipped with power steering systems, and there are three common types: mechanical hydraulic power steering systems, electro-hydraulic power steering systems, and electric power steering systems. Both electro-hydraulic and mechanical hydraulic power steering systems have a power steering pump and hydraulic mechanism, and both require the use of power steering fluid. If the power steering system malfunctions, it should be repaired immediately, otherwise it will affect the vehicle's driving stability and safety.
