How to Diagnose Mechanical Vehicle Issues From Sounds

When you make as big of an investment as purchasing a car, you want to make sure you uphold that vehicle's value as long as possible. Keeping it in pristine condition means ensuring you take it in for its regular car service at One Stop Auto Care. However, problems are inevitable as your car grows older, even if you do all the right things for your vehicle.


Automobiles are complicated machines, and it isn't uncommon for their parts to malfunction naturally. Luckily, you can diagnose most mechanical problems by just using your five senses. Today we are going over any noises your car may make that may signal a need for repairs.


Sound 1: Squealing or Screeching from below

This is a pretty popular noise that we sometimes hear in other vehicles around us. If you notice that your car is screeching or squeaking whenever you apply pressure on the brake pedal, it may mean that your brake pads have completely worn down. The noise is produced by the brake pad indicator rubbing against the rotor. Upon hearing this noise, you should get your brake pads replaced soon to avoid a dangerous accident.

Sound 2: A rattling sound coming from your wheel

If you hear a rattling noise coming from one of your tires, similar to moving a penny in a jar or soda can, then it may mean you have a loose bolt inside of your hubcap. This scenario occurs if one or more of your wheels are not tightened adequately from a recent tire change. 

Sound 3: A knocking sound

If you are cruising at a normal and consistent speed and hear a knocking or pounding noise, it could mean several things. One possibility behind this symptom is misaligned connecting rods. However, it could also signify that your vehicle needs an oil change or faulty bearing or crankpin. You're better off having this noise diagnosed by a professional.

Sound 4: A squeaking sound when turning 

If you discover a squeak or squeal whenever you make a turn, this could indicate that your steering column or power steering is at fault. You may just need to add more power steering fluid, which is an easy fix!
