What to Do When the Hydraulic Power Steering Wheel Becomes Heavy?

[StEloise]

Hydraulic power steering wheel becoming heavy is most commonly caused by dirty power steering fluid. Here is the relevant information: 1. Power steering fluid, like other automotive fluids, needs to be replaced. Another possible cause is low tire pressure, which can also make the steering wheel feel heavier and, in severe cases, may even lead to a tire blowout due to insufficient pressure. Therefore, when the steering wheel becomes heavy, first check the car's tire pressure and power steering fluid. 2. Nowadays, most vehicle models use hydraulic power steering systems, which are further divided into mechanical hydraulic steering and electro-hydraulic steering. Both work on a similar principle where a hydraulic pump (driven by the engine belt) provides oil pressure to push the piston, thereby generating auxiliary force to move the steering linkage and assist in wheel steering.
