What causes significant body sway when driving on slightly uneven roads?
3 Answers
Significant body sway when driving on slightly uneven roads is generally caused by two main reasons: 1. Issues with the drive shaft: When the vehicle is stationary, carefully observe if there is any noticeable movement in the drive shaft. If the movement is significant, it usually indicates a problem with the drive shaft. 2. Tire inspection: Carefully check the front and rear tires to ensure the tire pressure is consistent. Also, look for any signs of bulging or bubbling in the tires. If such issues are found, they should be replaced, and a four-wheel alignment should be performed. Here are some details about car tire pressure: 1. Detail one: Generally, car tire pressure should be checked at least once a month. It's important to adjust the tire pressure with each change of season. The ideal times for adjustment are in November and May. In November, as winter approaches, tire pressure usually decreases and should be slightly adjusted. 2. Detail two: In May, as the weather starts to get hotter, it's advisable to check if the tire pressure is normal. It's particularly important to note that as long as the tire pressure is not significantly higher than the standard range, there's no need to deliberately reduce it. If the tires are not under-inflated, there's no need to adjust the pressure every month.
I've experienced severe body shaking several times while driving on uneven roads. Initially, I thought it was normal, but after inspection, I found out it was mainly due to damaged shock absorbers. Shock absorbers are responsible for absorbing road impacts. If they are worn out or leaking oil, they can't absorb bumps effectively, causing the car body to sway easily. Another possible reason is tire issues, such as overinflation or underinflation, which can make the wheels unstable, especially worsening the shaking at high speeds. Additionally, incorrect wheel alignment can make the car's direction unstable, causing it to wobble on small bumps or uneven roads. It's recommended to first check the shock absorbers and tire pressure. If you can do it yourself, simply check if the tires are unevenly worn. If not, take it to a professional shop for a comprehensive inspection. Don't wait until something happens on the highway to regret it.
I just got my driver's license, and my new car had a slight bump and body shake issue, which turned out to be caused by uneven tire pressure or excessive wear. When the tire pressure is too high, the tires become very hard and bounce at the slightest unevenness; when the pressure is too low, they become too soft and wobble significantly when turning. A friend reminded me to regularly check tire pressure and wear. If the tread is uneven or aging and peeling off, poor grip naturally leads to an unstable body. Later, after replacing the tires, the problem was resolved. I also checked if the rims were deformed. Paying more attention to these details before daily driving can help prevent such issues.
