Why does my BMW make a noise when I turn?

Oceanside Motorsports • March 18, 2024

If your BMW is making a noise when you turn , it could be due to various factors. Common causes include worn-out steering components like tie rods or ball joints, issues with the power steering system such as low fluid levels or a failing pump, worn wheel bearings, faulty suspension components, or tire-related issues like uneven wear. 

Ignoring these noises can lead to further damage and compromise safety. It’s essential to have a qualified German auto repair inspect your BMW to diagnose the specific cause and address any underlying issues promptly. Taking proactive steps to address the noise ensures optimal vehicle performance and driving safety. Here at Oceanside Motorsports, we can find out what’s wrong with our diagnostic testing to ensure you’re only spending money on what needs to be fixed.

Several Factors

A noise when turning in your BMW could be caused by several factors, including the following. It’s important to have a qualified German mechanic like Oceanside Motorsports inspect your BMW to diagnose the specific cause of the noise and address any underlying issues. Ignoring unusual noises while driving can lead to further damage and potentially compromise safety.

  1. Steering Components

The steering system in your BMW is composed of various components such as tie rods, ball joints, and control arm bushings. Over time, these components can wear out due to regular use, exposure to road conditions, and other factors. When these parts become worn or damaged, they can produce clicking, knocking, or clunking noises when turning. Inspecting these components and replacing them if necessary is crucial to maintaining proper steering functionality and safety.

  1. Power Steering System

BMWs are typically equipped with power steering systems that assist in steering efforts, making driving more comfortable and manageable. Issues with the power steering system, such as low power steering fluid levels or a failing power steering pump, can lead to noise when turning the steering wheel. Low fluid levels can cause air to enter the system, resulting in a whining or groaning noise. A failing power steering pump may produce grinding or growling sounds. 

  1. Wheel Bearings

Wheel bearings allow the wheels to rotate smoothly while supporting the vehicle’s weight. Over time, wheel bearings can wear out due to factors like improper lubrication, contamination, or excessive loading. Worn-out wheel bearings often produce a grinding or humming noise, particularly when turning. If the noise becomes more pronounced when turning in one direction, it could indicate a problem with the wheel bearing on that side. 

  1. Suspension Components

The suspension system in your BMW plays a crucial role in providing stability, handling, and comfort while driving. Faulty or worn suspension components such as shocks, struts, or sway bar links can lead to noise when turning. Damaged shocks or struts may cause knocking or clunking sounds, especially when going over bumps or uneven road surfaces. Worn sway bar links can produce rattling or clunking noises when turning or driving over rough terrain. 

  1. Tire Issues

The tires on your BMW are the only points of contact between the vehicle and the road, making them critical for safety and performance. Uneven tire wear or tire damage can lead to noise when turning. Improper tire inflation, misalignment, or worn-out suspension components can cause uneven tire wear, resulting in noise and reduced handling. Inspecting the tires for signs of uneven wear, bulges, or damage, and ensuring they are properly inflated according to the manufacturer’s recommendations is essential for safe and quiet operation.
