Suspension or Wheel/Tire Issue Causing Shaking Over Bumps
The whole car shakes when going over bumps, which typically indicates a problem with the suspension system, wheel balance, or tire condition. Common causes include worn shock absorbers, loose suspension components, or tire issues.
Diagnosis Details
Possible Causes
Worn or leaking shock absorbers/struts – unable to dampen impact, causing excessive bouncing and shaking.
Loose or worn suspension components (control arm bushings, ball joints, sway bar links) – allow excessive movement over bumps.
Tire imbalance or out-of-round tire – vibration may be felt more over bumps if tire is damaged or unbalanced.
Wheel bearing wear – can cause shaking, especially when combined with bumps.
