Have you ever felt your car sway, lose grip, or wobble when changing lanes quickly, taking a corner, or driving over uneven roads? This “swaying” sensation is not just about reduced driving comfort; it’s a clear warning sign that your car’s suspension system is having problems and could lead to unexpected dangers.
What Causes Car Swaying? 4 Key Suspension Parts to Check
Swaying symptoms are often caused by the deterioration of crucial components in the suspension system, which are responsible for absorbing impacts and maintaining the stability of the vehicle. The points that should be checked first are:
1. Worn-Out Shock Absorbers
- Shock absorbers dampen the movement of the springs, keeping the car stable and hugging the road. But when shock absorbers wear out or “die,” they can no longer control the spring’s rebound.
- Symptoms: The car bounces up and down multiple times after going over a speed bump, oil leaks from the shock absorber body, the front of the car dips more than usual during hard braking.
2. Loose or Broken Sway Bar & Bushings
- This component directly prevents the car from “swaying” when cornering by distributing pressure to the opposite wheel to maintain balance.
- Symptoms: The car leans excessively when turning or cornering, there are rattling noises from under the car near the wheels.
3. Loose or Damaged Ball Joints
- Ball joints act as “connectors” in the suspension system, such as control arm ball joints and tie rod ends. When they become loose, it makes precise steering difficult.
- Symptoms: Loose steering wheel with slow response, clunking noises when turning the steering wheel or driving on rough roads, uneven tire wear.
4. Fatigued or Sagging Springs
- Springs directly support the weight of the vehicle. If they become fatigued or sag, it changes the car’s height and affects its center of gravity.
- Symptoms: One side of the car appears noticeably lower than the other, there are noises when driving over bridge joints.
