So, What Exactly Do Coil Springs Do?
Alright, let’s get down to brass tacks. Coil springs – or suspension springs – are sort of the unsung heroes under your car. They work along with your shock absorbers and struts, basically making your ride a whole lot smoother. Got a Toyota Hiace full of tools bouncing along Kahikatea Drive, or maybe you’re in a Honda Jazz ducking through the school run on Te Rapa Road? Coil springs are why you’re not bouncing around like you’re on a trampoline every time you hit a pothole or speed bump (we’ve got a few in Rototuna, right?).
When you go over bumps or rough bits – those gnarly potholes around Frankton or unexpected judder bars in Hillcrest – your coil springs compress, helping soak up the impact. They keep things balanced too, so the car doesn’t lean off to one side, even if you’re loaded up with groceries from The Base or carting the family from Cambridge to Hamilton East.
What Wrecks Your Coil Springs?
Look, we see it all the time in the workshop. Some cars just live a tougher life than others. If you’re hammering around Morrinsville roads or slogging your way out to Ngaruawahia on chilly winter mornings, that constant up-and-down, plus a bit of Waikato road grit, can wear down your springs. Over time, springs can get rusty, crack, or start to sag, especially if you’ve been carrying heavy gear or towing (shout out to all you Suzuki Grand Vitara owners hauling trailers).
Hamilton’s a bit notorious for four seasons in one day. Hot summers can speed up wear, then there’s all that wet, foggy stuff in winter – not exactly easy on your suspension. That’s when we start seeing springs corrode or snap right through.
How Do You Know If Your Coil Springs Are Knackered?
Here’s what we hear from customers all the time – and what we spot under the hoist:
- Car Sagging or Leaning: You’ll spot one corner of the car dropping lower, like your Nissan X-Trail is doing the limbo. It’s a dead giveaway something’s up.
- Feels Rough as Guts: If every little bump feels like a crater, or your morning drive into Hamilton Central shakes your teeth out, springs could be the culprit.
- Bottoming Out: Ever scraped your undercarriage heading over those relentless speed humps near Dinsdale? If your car’s thumping hard or wheels smack the arches, that’s a sign.
- Weird Clunks and Squeaks: Got a squeak or a nasty thud up front in your Peugeot 308 when you go over the lumps and bumps? Worn springs will do that.
- Strange Tyre Wear: Bald spots or uneven wear showing up? Springs keep your tyres where they belong – when they’re tired, your tyres cop it.
- Steering Feels Off: If your car’s body roll is worse than a rowboat in a storm, or the steering’s got a vague, floaty feel, that’s another red flag. Doesn’t matter if it’s a Mazda Demio or a Mercedes B-Class – old springs don’t discriminate.
How Important Is Getting Coil Springs Replaced?
Honestly, don’t muck about if your springs are shot. If you keep going, sooner or later something underneath will cop some damage. We’ve seen worn-out springs in a Kia Sportage chew out shocks and bushings, sometimes even leave the whole strut punching up into the wheel arch. Sort it early, save yourself some cash – and hassle.
A dodgy coil spring or leaking shock will fail a Warrant of Fitness (WOF). WOF Hamilton rules are dead set on proper suspension, so you won’t get that sticker until it’s fixed.
