Sometimes, it may seem like your car speaks its own language. Though you’re familiar with normal car sounds, you may encounter odd noises. Know when to seek help by looking at these vehicle noises that can indicate trouble.
A loud squealing or shrill sound when starting your car that gradually fades can mean a failing serpentine belt.
The serpentine belt is a long rubber belt around various pulleys and wheels in front of the engine. Depending on the model of your vehicle, the belt may be on the crankshaft or other systems, such as the AC compressor, alternator, and power steering system.
There are various reasons why a serpentine belt can make an odd noise, but the most common culprit is wear and tear. Over time, the rubber belt becomes brittle, causing it to crack and slip. Thus, it produces a squealing sound.
Rattling when driving over bumps is a vehicle noise that can indicate trouble. In particular, it can signal an issue with bushings inside your suspension system.
Bushings are synthetic or rubber parts in the suspension system that cushion various components, reduce friction, and prevent vibrations. If you have rubber bushings, you should be aware that they get brittle and break down. Bad bushings can be the reason why your car makes a rattling sound.
If you hear a low drumming or humming sound that increases while accelerating, you may have tire problems. The excessive noise is a sign your car needs a wheel alignment. Misalignments cause uneven wear and tear on your tires. You’ll have a bumpy ride and may encounter issues like a vibrating steering wheel.
Luckily, wheel alignment improves the way your car handles the road and extends the life of your tires. Professionals recommend wheel alignments once or twice a year. It’s a part of routine tire maintenance.
A rattling noise from inside your wheel can sound like a coin in a clothes dryer. If you hear rattling at low speeds that stop when you accelerate, that can mean a loose nug inside your hubcap. You may not have properly tightened your wheel after recently removing and replacing your tire. Take your car to the mechanic to tighten the loose nug. The last thing you want is tire damage.
