What do suspension bushes actually do?
Alright, so you’re probably wondering what those suspension bushings (or bushes, as we usually call them) actually do. In simple terms, these are rubber bits that sit between all the solid metal parts of your car’s suspension – places like the control arms, sway bars, and the area round the shocks. That little bit of rubber does a big job: stops the metal bits from clanging into each other, keeps stuff lined up, and soaks up heaps of shakes and bumps from the road.
Especially round Hamilton – think Fifth Ave, Te Rapa Straight, all those spots with a rough patchwork of tar, or heading out towards Cambridge or into the hills of Ngaruawahia – bushes help keep your ride from rattling to bits and make sure the tyres stay squared up on the road. Feels way better and keeps your suspension behaving. Bushes work together with your shock absorbers to smooth things out, whether you’re in a hybrid Toyota Aqua zipping through Hillcrest, a Mazda Demio, or even a late-model Skoda Octavia.

When do bushes need replacing?
Here’s the honest answer: bushes do last, sometimes ages, but they’re not invincible. They’re under pressure every time you hit a pothole or bounce through traffic over by Chartwell or Nawton. Over time – especially with that combo of Hamilton’s foggy wet winters and then baking heat in summer – they crack up, squash, or just start falling to bits. Even brand-new Audis and utes aren’t immune, but you’ll see it even sooner if you’re driving back and forth to Morrinsville on those rough rural roads, or if you’re someone who needs a car service Hamilton way while constantly braving the potholes.
Honestly, some bushes outlast the car, but if you’re getting lots of sharp bumps, have to cross the nightmare of speed cushions down Ulster St every day, or park in long grass outside your place in Tamahere, the rubber just goes hard and starts cracking quicker. Big, heavy SUVs—think Nissan X-Trails, Honda CRVs or even the odd SsangYong—we see those quite a bit with worn bushes from rough roads or towing.
How to make your suspension bushes last longer:
- Take it slow over speed bumps and potholes – saves more than your teeth, eh?
- Try not to drive up kerbs, even when you’re in a rush on Victoria Street grabbing a coffee.
- Stay clear of manhole covers and dodgy patches if you can. We know that’s easier said than done some mornings!
- If you’re leaving the car sitting for ages, especially on grass or in the weather, that can make the rubber rot out faster.
What are the signs your suspension bushes are shot?
We get a mix of folks popping in, from a family in a Suzuki Swift to an older gent with his ancient Mercedes E-Class. The stories are always the same: loud clunks over bumps, weird wobbles, tyres wearing quicker on one side (the tyre shop loves that), or the steering just feels kind of floaty – like you’re swimming down Grey Street instead of driving.
- Loud clunks or rattles – Could be the bushes letting the metal arms knock about underneath.
- Uneven tyre wear – Car starts leaning or pulling, especially noticeable on longer trips out to Raglan.
- Loose, vague steering – People say it feels like you’re not fully in control, especially on roundabouts or sidestreets with dodgy camber.
- Rubber looking cracked or perished – If you have a look underneath, you might see the rubber’s split or crumbly. If it looks bad, it is bad!
Is it dodgy to drive with bad bushes?
Short answer – yeah, it’s a risk. Buggered bushes mean your suspension can’t keep everything steady, and that affects how your car handles, brakes, and steers. That’s not something you want going wrong bombing through the 50km/h zones on Avalon Dr or if you have little ones on board.
Get them sorted quickly and you’ll avoid bigger drama – plus it’ll make your ride nicer, save the tyres and keep you arrow-straight for the next WOF Hamilton does.
