Suspension components — shock absorbers, bushes, ball joints, steering linkages — are designed to last a certain number of kilometres under normal conditions. Alice Springs is not normal conditions.
Corrugated roads create continuous high-frequency vibration. That vibration accelerates wear on every rubber bush and ball joint in the suspension system. What might last 80,000km in a city car can be worn out at 40,000km on the Plenty Highway.
What You'll Notice (and What You Won't)
Worn suspension often announces itself: vibration through the steering wheel, pulling to one side, excessive body roll in corners, a knock over bumps. Those are the obvious signs.
The less obvious ones: tyres wearing unevenly, handling that just feels "not quite right", or a vehicle that drifts more than it used to on corrugated roads.
Worn bushes and ball joints often give very little warning before they fail significantly. If you're heading remote, you don't want to find out the hard way.
The Alignment Connection
Worn suspension causes alignment to drift. Misaligned wheels cause rapid tyre wear — sometimes destroying a tyre in 10,000km that should last 40,000. An alignment check tells you a lot about the health of your suspension.
When to Get It Checked
If you're noticing any of the symptoms above, or if you've done significant corrugated road kilometres, come in for an inspection. We'll check the whole system and tell you what needs attention and what can wait.
