Are Clunking Noises A Sign Of Suspension Trouble In Lexus Vehicles?
When your high-end Lexus starts making unusual noises, especially from the suspension, it can be both concerning and confusing. From clunks to creaks, these sounds often indicate that something within your suspension system needs attention. The suspension system of a vehicle absorbs shocks from the road and maintains tire contact with the surface. It enhances both your vehicle’s handling and safety.
Keeping your suspension system in good health is essential for optimal vehicle performance. However, unusual noises—such as clunking—may indicate issues that must be addressed immediately. At Orion Automotive Services, located near you in Ann Arbor, MI, we specialize in suspension noise repair and are here to help you understand what these noises mean and how you should address them based on their severity.
3 Top Reasons You Might Hear Clunking Noises in Your Lexus
1. Worn-Out Control Arm Bushings
- Why This Happens: Control arms connect the wheels to the body of your Lexus and allow the suspension to move up and down over bumps. Inside each control arm, there are rubber bushings that absorb the shock and prevent metal parts from rubbing together. Over time, heat, cold, road salt, and everyday driving make this rubber dry out. The bushings crack, harden, and eventually wear away. When this happens, the control arm loses its cushion, and the metal parts make direct contact, causing a clunking noise and loose, smooth handling.
- How to Fix: On Lexus models, this usually means replacing the entire control arm or installing new, high-quality bushings. This restores tight handling, smooth driving, and the solid road feel the car is designed to deliver.
2. Failing Struts and Shocks
- Why This Happens: Struts and shocks control how your Lexus handles bumps and keep the ride smooth and comfortable. They slow the suspension’s up-and-down movement, keeping the car stable even on bumpy roads. Over time and miles, these internal parts wear out. Hard impacts from potholes or rough roads can damage internal seals and valves. This makes the shock’s fluid leak out, and the strut loses its ability to control movement. Hence, the car bounces more than it should, and you hear a hollow clunking noise every time you drive over bumps.
- How to Fix: Expert technicians at Orion Automotive Services, serving in Ann Arbor, replace the worn-out struts or shocks. These parts are always replaced in pairs, either both fronts or both rears. Changing those keeps the car level, stable, and safe to drive. New struts restore the smoothness and quietness for which Lexus is known.
3. Damaged Ball Joints
- Why This Happens: Ball joints connect the suspension to the wheels and allow the wheels to move up, down, and side to side while steering. These joints work like the Knee-Joints in the human body and carry a lot of weight every time the car moves. Over time, the protective rubber boot around the ball joint wears away, allowing grease to leak out and dirt and grit to get inside. The metal parts start to grind against each other, causing the joint to wear out quickly. As the joint loosens, it begins to make popping or clunking noises, especially during turns or at low speeds.
- How to Fix: The correct repair is to replace the worn ball joint right away. A damaged ball joint is a serious safety concern because it holds the wheel in place. Replacing it restores tight steering, eliminates noise, and ensures the wheel remains securely connected to the suspension. This repair protects both the car and the driver from dangerous suspension failure.
