Clunking Noise Over Bumps: Causes
A clunk over bumps usually means worn suspension — and a safety/roadworthy concern. A Cranbourne West specialist explains.
What it usually means
Clunking over bumps commonly points to worn suspension or steering components: control-arm bushes, ball joints, sway-bar (anti-roll bar) links, strut mounts, or worn shock absorbers. Each makes a slightly different noise.
Sway-bar links are a common, cheap culprit; ball joints and bushes are more important for safety.
What you should do
Have it inspected — worn suspension affects handling and braking, and several of these items are roadworthy failures. Catching a cheap link early avoids further wear.
We’ll pinpoint exactly which component is knocking.
How we find & fix it
Because the same symptom can have several causes, we use dealer-level diagnostics and a methodical check to pinpoint the real cause — rather than throwing parts at it.
