What Causes a Car to Sway Left and Right?
2 Answers
A car swaying left and right may be caused by abnormal tire pressure. Below are solutions for addressing car swaying issues: 1. Solution 1: The tire pressure values of all four tires should not differ significantly, typically within 0.1 bar. Excessive differences in tire pressure can lead to inconsistent energy absorption and shock absorption capabilities between tires, resulting in body vibration at high speeds. 2. Solution 2: Inspect the rims for deformation, commonly referred to as out-of-round wheels. Deformed rims can cause left-right swaying. If the rims are deformed, replace them. 3. Solution 3: Whether a wheel alignment is needed can only be determined after inspection at an auto repair shop. It is recommended to promptly visit a 4S store or auto repair shop for inspection to identify the issue and proceed with targeted repairs.
I've been driving for over a decade and often encounter situations where the car sways from side to side, mostly due to tire issues. I remember that time on the highway when the car shook violently, which really scared me. Later, a check revealed it was caused by uneven tire pressure—the two front tires had a significant pressure difference. Another time, it was because the suspension system had loosened; the screws on the lower control arm had come loose, making the car wobble when turning. Before hitting the road, I always do a quick check on tire wear and pressure balance to prevent these issues from worsening. Ignoring these small things can seriously affect braking distance or even lead to accidents. It's best to go for a comprehensive check at a repair shop regularly—it doesn't cost much but ensures peace of mind while driving.
