Diagnosing Drivetrain Noises
Wednesday, September 26th, 2007Part of getting good service from your mechanic is accurate communication of noises and symptoms of the car trouble you are having. Here is a quick look at the most common drivetrain noises you may hear and the possible problems.
- Low frequency vibration when turning a corner usually points to a wheel bearing going bad. This usually sounds like a thump…thump…thump noise and varies with speed and how hard you are turning. To diagnose, your mechanic will raise your vehicle off the ground and check the amount of play in the wheel bearings. You can do this yourself with a jack in your driveway.
- High frequency clicking when making low speed sharp corners is a classic sign of a CV joint going bad. Front wheel drive vehicles use a constant velocity joint which can wear over time. If the boot which protects the joint from dust and keeps grease in, is damaged the wear can happen even quicker.
