Clunking Noise from Front Suspension on 2020 QX60

Vehicle: 2020 Infiniti QX60 Luxe

Hi all,

I've got a 2020 Infiniti QX60 Luxe, and lately, I've been hearing a noticeable clunking noise from the front end, especially when going over speed bumps, potholes, or uneven pavement. It's more prominent on the driver's side, but I can hear it from both sides sometimes.

The car has about 60,000 miles on it. It drives fine otherwise, no pulling or major steering issues, but the sound is concerning. It almost sounds like something is loose.

Has anyone experienced this with their QX60? What are the usual suspects for this kind of noise? I'm hoping it's not something major.

ClearTheCode admin answer:

A clunking noise from the front suspension is a common complaint and often points to worn or loose components. Given your 2020 QX60's mileage, several parts could be reaching the end of their service life.

Common Causes of Front Suspension Clunking:

  • Worn Sway Bar End Links: These are a very common culprit. The ball joints on the end links can wear out, causing a clunking noise as the suspension articulates.
  • Worn Control Arm Bushings: The rubber bushings in the lower or upper control arms can crack, tear, or degrade, leading to play and noise.
  • Bad Ball Joints: If the lower or upper ball joints are worn, they can cause clunking, especially over bumps.
  • Loose Strut Mounts or Worn Struts: The top mounts for the struts can wear out, or the struts themselves might be failing, leading to noise and reduced damping.
  • Loose Subframe Bolts: Less common, but subframe bolts can sometimes loosen, causing a clunk.
  • Damaged Tie Rod Ends: Inner or outer tie rod ends can wear, creating play and noise, though this often comes with steering issues.

Troubleshooting Steps:

  1. Visual Inspection (Parked): With the vehicle on a flat surface, try pushing down on each corner of the front end to see if you can replicate the sound or feel excessive play. Look for obvious signs of damage or leaks around the struts.
  2. Professional Inspection: This type of issue is best diagnosed by a professional. They will lift the vehicle and use pry bars to check for play in various suspension components (ball joints, control arm bushings, tie rod ends, sway bar links).

When to See a Shop:

  • Immediately: If the clunking is severe, accompanied by steering issues (like wandering or excessive play), or if you notice any visible damage to suspension components.
  • Soon: Even if it's just an annoying noise, worn suspension components can affect handling, tire wear, and potentially lead to more serious failures if left unaddressed. It's best to have it inspected to prevent further damage or safety concerns.
