Whole Car Shakes Over Bumps
The vehicle shakes or vibrates when driving over bumps, indicating a possible issue with the suspension or steering components. This symptom suggests that the damping or structural integrity of the suspension is compromised, leading to excessive movement transmitted to the chassis.
Diagnosis Details
Possible Causes
Worn or damaged shock absorbers or struts that no longer properly dampen suspension movement, causing the vehicle to bounce or shake over bumps.
Loose or worn suspension bushings (control arm, sway bar, or strut mount bushings) allowing excessive play in the suspension system.
Broken or weakened coil springs that fail to support the vehicle's weight, leading to uncontrolled motion over bumps.
