A Guide to Common Suspension Problems

Suspension and steering issues tend to creep up gradually, which makes them easy to ignore until they're either expensive or unsafe. Here's how to read the signs your car is actually giving you.

Clunking or knocking over bumps

A distinct clunk or knock when driving over speed bumps, potholes or uneven road (Perth has no shortage of these) usually points to worn suspension components — commonly sway bar links, bushes, or worn ball joints. These components are designed to absorb small movements quietly; when they wear out, that movement translates into noise and a looser, less controlled feel.

The car pulls to one side

If your car consistently drifts left or right when driving straight on a flat road (and it's not windy), the most common causes are:

• Wheel alignment out of specification
• Uneven tyre pressures
• A worn or failing suspension component on one side
• In rarer cases, brake caliper drag on one wheel

This is worth addressing sooner rather than later — beyond the annoyance, it accelerates uneven tyre wear and can be a sign of a genuine mechanical fault rather than just an alignment issue.

Excessive bouncing after a bump

If your car continues to bounce more than once or twice after going over a bump, rather than settling quickly, this is a classic sign of worn shock absorbers or struts. Their job is to dampen the spring's movement — when they wear out, the spring keeps bouncing with less control, which affects both comfort and handling, particularly under braking.

Uneven or unusual tyre wear

Your tyres are one of the best diagnostic tools for suspension health, if you know what to look for:

• Wear on the inside or outside edge only — often points to alignment issues or worn control arm bushes
• Cupping or scalloping (a wavy wear pattern) — often indicates worn shock absorbers or struts
• Wear on one tyre significantly more than its pair — can indicate an alignment or suspension issue isolated to that side

A "loose" or vague steering feel

If the steering wheel feels like it has more play than usual before the wheels respond, or feels vague and less precise, worn tie rod ends or steering rack components are common culprits. This directly affects your ability to make precise steering corrections, so it's worth having checked promptly rather than adapting to it.

Vibration through the steering wheel

Vibration that increases with speed can point to a wheel balance issue, but persistent vibration regardless of speed, especially combined with other symptoms above, can indicate worn suspension or steering components rather than a simple balance problem.

Why suspension issues matter beyond comfort

Beyond ride quality, your suspension and steering system is directly responsible for keeping your tyres in proper contact with the road — which affects braking distance, cornering stability and overall control. Worn components don't just make for a rougher ride; they genuinely compromise how your car handles in an emergency situation.

Getting it checked

If any of these symptoms sound familiar, it's worth having your suspension and steering properly inspected rather than waiting for it to get worse. See our suspension & steering service, or call 0411 949 959 and we'll come to you to have a look.
