Why is the steering wheel so heavy?
1 Answers
The reasons for a heavy steering wheel are as follows: 1. Insufficient power steering fluid: Power steering fluid is a medium oil used in the car's power steering pump, which transmits steering force and provides cushioning. The power steering fluid needs to be replaced regularly, and any leaks should be checked. When the power steering fluid is insufficient, the steering will become heavy. 2. Low tire pressure: Low tire pressure increases the contact area between the tire and the road surface, leading to greater friction and difficulty in steering, resulting in a heavy steering wheel, which is not conducive to driving safety. In this case, the tire pressure should be replenished promptly. 3. Overly tight bearing fit: For the rolling bearings connected to the steering system, if they are too tightly fitted with the sliding bearings, it can prevent proper lubrication of the bearings, leading to sticking issues and causing the steering wheel to become heavy. In this case, the mechanical parts and the power steering system should be inspected, or checked for oil leaks or damaged intake seal components. 4. Power steering system issues: The steering wheel and the power steering system are closely related. Therefore, when the steering wheel becomes very heavy, it may also be due to poor electrical contact or other issues within the power steering system. In this case, it should be inspected and repaired at a 4S shop.
