Read moreWhy Is My Car Making That Sound?
Strange car noises are easy to ignore at first, especially if your vehicle is still driving normally. However, a new squeak, grind, rattle or knocking sound can be an early warning that a component needs attention. Identifying the sound and when it occurs can help prevent a minor issue from becoming a more expensive repair.
At Hilaire and Speer Auto's, we provide thorough vehicle inspections and mechanical repairs to help drivers get to the bottom of unusual car noises.
Squealing When You Start or Accelerate
A high-pitched squeal from under the bonnet may be caused by a worn or loose drive belt. Your vehicle’s belts help run important components such as the alternator, water pump and air conditioning system. If a belt is slipping, cracked or worn, it should be checked promptly.
Squealing can also occur when braking. In some cases, brake pads have wear indicators designed to make a noise when the pads are getting low. A brake inspection can confirm whether the pads, rotors or other components need attention.
Grinding or Scraping When Braking
Grinding, scraping or harsh metal-on-metal noises when pressing the brake pedal should never be ignored. This can indicate severely worn brake pads, damaged brake rotors or another brake system concern.
As braking performance is essential to your safety, book an inspection with Hilaire and Speer Auto's as soon as possible if you notice grinding, vibration through the pedal or a change in how your vehicle stops.
Knocking, Clunking or Banging Over Bumps
A clunking noise when driving over speed bumps, potholes or uneven roads may point to worn suspension or steering components. Possible causes can include worn shock absorbers, bushes, ball joints, sway bar links or engine mounts.
These parts help keep your vehicle stable, comfortable and predictable on the road. If your car is also pulling, bouncing excessively or feeling less controlled, it is a good idea to have the suspension and steering checked.
Clicking When Turning
A repetitive clicking or ticking sound while turning, particularly at low speeds or on full lock, can be a sign of a worn CV joint. CV joints transfer power to the wheels while allowing them to turn and move with the suspension.
Leaving a damaged CV joint unchecked can lead to further driveline damage, so arrange an inspection before the issue worsens.
Humming, Roaring or Growling While Driving
A humming, droning or growling sound that becomes louder as your speed increases may be related to tyres, wheel bearings or driveline components. Uneven tyre wear can create excessive road noise, while a worn wheel bearing may become more noticeable when turning or changing lanes.
A professional inspection can help identify the source and ensure the issue is repaired correctly.
Rattling From Underneath the Car
A rattle underneath your car may be caused by a loose exhaust heat shield, worn exhaust mounting, damaged exhaust component or loose underbody fitting. While some rattles may be relatively minor, others can indicate an exhaust leak or a component that needs securing.
If the noise is accompanied by exhaust smells, reduced performance or a warning light, have it checked as soon as possible.
Whistling, Hissing or Air-Like Noises
Hissing or whistling from the engine bay can sometimes be caused by a vacuum leak, intake issue, cooling system leak or a loose hose. If you notice overheating, steam, coolant loss or a warning light along with the sound, pull over safely and seek advice before continuing to drive.
Don’t Guess—Book a Car Noise Inspection
Your car should not suddenly develop new noises without a reason. While not every sound means an urgent repair is needed, early diagnosis is the best way to protect your vehicle, your safety and your budget.
If your car is making a strange sound, book an inspection with Hilaire and Speer Auto's. Our experienced technicians can assess the noise, identify the cause and recommend the right repair to help keep your vehicle driving safely and reliably.
