How to Adjust the Heavy Steering Wheel of Mercedes-Benz C-Class to Make It Lighter?
1 Answers
Start the car, keep the steering wheel stationary for 3 seconds, then turn it to the full lock position and hold for another 3 seconds before returning it to the center and turning off the engine. Try driving to see if the steering wheel becomes lighter. Below are the reasons for a heavy steering wheel: 1. Insufficient power steering fluid: Power steering fluid is a medium oil used in the car's power steering pump, which helps transmit 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 feel heavy and stiff. 2. Low tire pressure: Low tire pressure increases the contact area between the tires and the road surface, leading to greater friction and making steering more difficult, resulting in a heavy steering wheel, which is not conducive to driving safety. 3. Toe-in: Toe-in can also affect the car's steering. Toe-in helps the steering wheels automatically return to the center, ensuring stable straight-line driving. If there is an issue with this, it can cause the steering to feel heavy. 4. Steering gear or power steering pump failure: The steering gear and power steering pump also affect the car's steering. Any failure in these two critical components can make steering difficult. Issues such as universal joints, chassis suspension stabilizer bars, or plain bearings should not be overlooked.
