What Causes Heavy Steering Wheel in Trucks?

[VanMakayla]

Reasons for heavy steering wheel in trucks include: insufficient power steering fluid, contaminated power steering fluid, or issues with the power steering system. Additionally, during winter when temperatures are low, the slower movement of air molecules can cause a slight decrease in tire pressure, increasing the contact area between the tires and the ground, making the steering wheel feel heavier. Specific explanations are as follows: 1. Insufficient power steering fluid: Power steering fluid is the primary source of driving force for a vehicle. Therefore, when there is insufficient power steering fluid, the vehicle naturally struggles to move, let alone turn or change direction. 2. Contaminated power steering fluid: If the vehicle has difficulty turning the steering wheel, it may be due to the power steering fluid being mixed with unclean gases or impurities, preventing it from functioning properly and driving the vehicle. 3. Issues with the power steering system: The relationship between the steering wheel and the power steering system is naturally inseparable. When the steering wheel becomes heavy, it is highly likely that there are issues such as poor electrical contact or other problems within the power steering system.
