Front end clunking noise over bumps in my 2020 RDX Advance

Vehicle: 2020 Acura RDX Advance

Hi all, I've got a 2020 Acura RDX Advance, and for the past few weeks, I've been hearing a distinct clunking noise from the front end. It's most noticeable when I go over speed bumps, potholes, or uneven pavement at low to moderate speeds.

The sound seems to come from both sides, but sometimes it's more prominent on the driver's side. It's not a constant rattle, just a single 'clunk' or 'thud' when the suspension compresses or extends quickly.

I'm worried it might be something serious with the suspension. Has anyone else experienced this with their RDX? What should I be looking for?

ClearTheCode admin answer:

A clunking noise from the front suspension, especially over bumps, is a common complaint and usually points to worn or loose suspension components. For your 2020 Acura RDX Advance, here are the most likely culprits and what to check:

  1. Sway Bar End Links: These are very common failure points. The bushings or ball joints in the end links can wear out, causing a clunking sound as the sway bar moves. This is often more noticeable over uneven surfaces or when one wheel articulates independently.
  2. Control Arm Bushings: The bushings that connect the control arms to the chassis can degrade over time. When worn, they allow excessive movement, leading to clunking, especially during suspension travel.
  3. Strut Mounts/Bearings: The top mounts of your struts can wear out, causing noise when the strut moves. The strut bearing, which allows the strut to rotate with steering, can also fail and produce clunking or popping sounds.
  4. Ball Joints: Worn lower or upper ball joints can also cause clunking. These are critical for steering and suspension integrity.
  5. Loose Components: Less common, but sometimes a loose bolt on a suspension component or even a loose brake caliper can mimic a suspension clunk.

Causes:

  • Normal wear and tear on rubber bushings and ball joints.
  • Exposure to harsh road conditions (potholes, rough roads).
  • Corrosion or lack of lubrication in moving parts.

When to See a Shop: It's crucial to have a professional mechanic inspect your suspension system promptly. Worn suspension components can affect handling, tire wear, and overall safety. A technician can lift the vehicle, inspect all bushings, ball joints, and end links for play or damage, and accurately pinpoint the source of the noise. Driving with severely worn suspension parts can lead to further damage or even loss of control.
