What are the reasons for the heavy steering wheel of the Buick LaCrosse?

[JoyMarie]

The reasons for the heavy steering wheel of the Buick LaCrosse are as follows: 1. Insufficient power steering fluid: Power steering fluid is a medium oil used in the car's power steering pump, which serves to transmit steering force and provide 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. Steering gear or power steering pump failure: The steering gear and power steering pump are also critical components affecting car steering. Any malfunction in these two important parts can cause steering difficulties. Issues such as universal joints, chassis suspension stabilizer bars, or plain bearings should not be overlooked.
