Guide to Diagnosing and Fixing Squeaking Noise in Cars When Turning

There is nothing more worrying than hearing unusual noises coming from your car. One such noise is the squeaking sound that can occur when you are turning. This comprehensive guide will walk you through the steps to diagnose and fix this issue.

Step 1: Identifying the Source

Squeaking noises during turns can come from several places, including the steering system, the suspension, or the tires. Pay close attention to the noise and when it happens to help identify its source.

Step 2: Inspecting the Steering System

  1. Check the Power Steering Fluid: If the noise is coming from the steering system, it could be due to low power steering fluid. Check the fluid level and refill if necessary.
  2. Examine the Power Steering Pump: A failing power steering pump can cause squeaking noises. If the fluid level is fine, the pump may need replacement.
  3. Inspect the Steering Belt: A worn or loose steering belt can also produce a squeaking sound. Inspect the belt for signs of wear or looseness, and replace or adjust as needed.

Step 3: Checking the Suspension

If the squeak is not originating from the steering system, it may be coming from the suspension. Here's how you can inspect it:

  1. Inspect the Struts and Shocks: These components absorb shocks from the road. Worn out struts and shocks can squeak, especially when turning.
  2. Check the Bushings: The bushings on the control arms, sway bars, and other suspension components can squeak if they're worn or dried out. They may need to be lubricated or replaced.
  3. Look at the Ball Joints: Worn out ball joints are a common cause of squeaking noises. They may need to be replaced.

Step 4: Inspecting the Tires

Lastly, don't forget to check the tires. Improperly inflated, misaligned, or worn-out tires can cause squeaking noises when turning.

Step 5: Fixing the Problem

Once you've identified the source of the squeak, you can take the necessary steps to fix it. This might involve replacing parts, lubricating components, or simply inflating your tires properly. If you're not comfortable doing these tasks yourself, take your vehicle to a professional mechanic.


A squeaking noise when turning can be a symptom of several different issues with your vehicle. By following this guide, you can identify the source of the problem and take steps to resolve it. However, if you're uncertain about any part of this process, it's always best to consult a professional mechanic to ensure your vehicle's safety and performance.
