Suspension or Brake Component Noise Over Bumps
A noise from the wheels or brakes when going over bumps in a 2020 Subaru Outback likely indicates a worn suspension component (such as a sway bar link, strut mount, or bushing) or a loose brake part (like a caliper or pad). The sound is triggered by vertical movement, pointing to a mechanical looseness or wear.
Diagnosis Details
Possible Causes
Worn or loose sway bar end links – these connect the sway bar to the suspension and often clunk over bumps.
Worn strut mounts or bushings – can cause knocking or creaking when the suspension compresses.
Loose brake caliper or worn brake pad hardware – the caliper may rattle if mounting bolts are loose or if anti-rattle clips are missing.
Damaged control arm bushings or ball joints – less common but can produce clunks over irregularities.
