What are the reasons for the heavy steering wheel of Mazda 3?

[McCora]

Mazda 3 steering wheel heavy reasons are as follows: 1. Insufficient power steering fluid/oil: Power steering fluid is a medium oil used in the car's power steering pump, which plays a role in transmitting steering force and buffering. The power steering fluid needs to be replaced regularly, and check for leaks. When the power steering fluid is insufficient, the steering will become heavy and stiff. 2. Low tire pressure: Low tire pressure will increase the contact area between the tire and the road surface, increase friction, make steering more difficult, and cause the steering wheel to feel heavy, which is not conducive to driving safety. 3. Toe-in: Toe-in can also affect the car's steering. The meaning of toe-in is quite complex. Simply put, it is to make the steering wheel automatically return to the center, ensuring that the car can drive straight stably. Therefore, problems in this aspect will also cause the steering to feel heavy.
