Whole Car Shakes Over Bumps
The vehicle experiences a whole-car vibration or shaking specifically when driving over bumps. This suggests a suspension or steering component issue, such as worn bushings, loose connections, or unbalanced components that are aggravated by road irregularities.
Diagnosis Details
Possible Causes
Worn or damaged suspension bushings (e.g., control arm bushings, sway bar bushings) causing excessive play and vibration over bumps.
Loose or worn steering components (tie rod ends, ball joints) leading to instability and shaking when the suspension is compressed.
Unbalanced or out-of-round tires/wheels that become more noticeable over bumps due to impact forces.
