Hearing a grinding sound when turning your Commodore is never a pleasant experience. It tends to creep in slowly, just a faint noise at first, but before long, it can become a full-on groan every time you steer. For owners of older vehicles, especially Holdens like the VL or VN, it’s a common problem. Over years of driving, key parts wear down or shift slightly in ways that surface during turns.
This noise often points to wear in common Holden Commodore car parts, and with age comes a greater chance those components have loosened, seized, or fallen out of spec. With cooler months still hanging around parts of Australia, these issues become even more noticeable. Low temperatures make dry joints stiffer and worn components more obvious. Let’s dig into what usually causes that uncomfortable grinding and what might be going on beneath the noise.
Steering Components That Wear Out
Turning puts pressure on parts most of us don’t think about day to day. Your steering works fine most of the time, until it doesn’t. Grinding during turns often starts in the joints and connections that direct your wheels.
- Dry or worn tie rod ends can grind slightly as you turn, especially under load
- Ball joints that are tired or lacking grease will make noise when they shift awkwardly with movement
- Lower control arm bushes don’t just affect suspension, they flex when you steer and can scrape or creak when they’re cracked or slipping
- The steering rack itself, especially on older Commodores, might be partly dry. If internal parts have worn seals or the rack is misaligned, it can grind or shudder during use
If these components haven’t been checked in a while, the noise during turns is often your first heads-up that they’re near the end of their working life.
Brake System Contact Points
It’s easy to blame everything on the steering, but sometimes the grinding comes from brake-related parts that shift just enough when you turn.
- Brake pads that are partly seized or dragging can rub when the caliper flexes slightly during a turn
- If backing plates have rusted tabs or been knocked loose, they can make light contact with the rotor edge when the wheel angles
- Worn wheel bearings aren’t just about noise at speed, when turning, the uneven load can make the grinding more noticeable on one side
If you only hear the grinding on certain turns and it changes with speed or load, suspect the brake system or bearing contact first.
Suspension and Wheel Alignment Issues
Suspension affects more than just ride comfort. It shifts under tension during every turn and can grind when springs or mounts start to wear unevenly.
- Poor wheel alignment means the tyres steer under stress, often dragging slightly across the road and creating a dry scrubbing sound
- If your springs have sagged over time, they might allow parts to drop lower and touch nearby surfaces at full lock
- Struts that are leaking or compressed no longer support movement evenly and may allow the wheel to shift just enough to lightly rub something it shouldn’t
- When wheel arch liners or trim panels are close to the tyres, any extra movement can cause contact, especially if bushings have gone soft
Grinding caused by alignment or suspension tends to build gradually. You might not hear it one day, then notice it suddenly on a slow tight turn like into a carpark or driveway.
Old or Poorly Fitted Replacement Parts
Not every Holden Commodore part you fit will behave like a factory one. We’ve seen plenty of problems come from mismatched or worn aftermarket parts, and they often become most obvious when turning.
- Parts that don't quite match OE specs may be barely noticeable until operating under cornering load
- Cheap or loose-fitting components can shift under pressure, especially if washers or spacers weren’t installed the right way
- Over time, fatigue in brackets and mounts causes parts to sag or lean where they were once tightly set
Sourcing used Holden Commodore car parts or installing older components without confirming fitment can increase the risk of grinding from places you wouldn’t expect, like under the strut or near the backing plate.
How to Spot the Problem Before It Gets Worse
Noises like grinding tend to start off small and go unnoticed, especially in winter when you’re less likely to roll the windows down. But there are common warning signs to keep an ear out for.
- Any grinding that changes depending on turning angle should be checked immediately
- Clicking or jerking on full lock could suggest CV, bearing, or alignment issues
- Uneven tyre wear, especially on the inner or outer edge, is a red flag worth investigating
- If you’ve had the car sitting over winter and just started driving it again, twisting noises could be your first sign of dry or rusty fittings working loose
It doesn’t take long for a minor issue to wear down other parts attached to the same system. A dry ball joint, for example, puts stress on both the tie rod and the mount, leading to more problems than just noise.
Turn Noise into Smooth Driving
Grinding when turning isn’t something to ignore. When you hear it, your car is trying to tell you something’s moved, shifted, or broken down more than it should. Aside from comfort, this wear affects how your Holden steers and handles, even if it doesn’t feel dangerous at first.
These types of issues tend to build gradually in older cars. Regular checks help uncover problems before they turn into part failures or expensive repairs. While many newer cars have better insulation or electronic steering setups, Commodores rely on mechanical feedback you can hear and feel. Staying tuned into those little sounds, like grinding, helps keep the car running confidently on every corner.
