Clunking noise from front suspension on 2017 Nissan Altima SL - what's worn?

Vehicle: 2017 Nissan Altima SL

Hi everyone, I've got a 2017 Nissan Altima SL with about 85,000 miles on it, and I've started hearing a noticeable clunking or popping noise from the front end. It's most apparent when I go over speed bumps, potholes, or even when turning sharply at low speeds. It sounds like something is loose or worn out.

I'm trying to figure out what the most common culprits are for this type of noise on an Altima of this vintage. Could it be sway bar links, control arm bushings, or something else entirely? I haven't hit anything major recently, so I'm assuming it's just normal wear and tear.

Has anyone else experienced this with their 2016-2020 Altima? What did you find was the problem, and what was the cost to fix it? I'd like to have an idea before I take it to a shop.

ClearTheCode admin answer:

A clunking or popping noise from the front suspension of your 2017 Nissan Altima SL is a very common complaint as vehicles approach and exceed 80,000 miles. This typically indicates wear in one or more suspension components. It's important to address these issues not only for comfort but also for safety and proper vehicle handling.

Here are the most common culprits for such noises:

  1. Sway Bar End Links: These are arguably the most frequent cause of front-end clunking. The ball joints or bushings in the end links wear out, creating play that results in a clunking sound, especially over uneven surfaces or when turning. They are relatively inexpensive to replace.

  2. Control Arm Bushings: The lower control arms have rubber bushings that can crack, tear, or degrade over time. When these bushings fail, the control arm can shift slightly, causing a clunk. This can also affect alignment and tire wear.

  3. Strut Mounts/Bearings: The top strut mounts (also called strut bearings) can wear out, leading to a clunking or popping noise, particularly when turning the steering wheel or going over bumps. If the strut itself is also worn, it might contribute to the noise and poor ride quality.

  4. Ball Joints: While less common than sway bar links or control arm bushings, worn lower ball joints can also produce a clunking sound and are a critical safety component.

  5. Tie Rod Ends (Inner or Outer): Worn tie rod ends can cause clunking, especially when turning, and can also lead to loose steering feel.

When to See a Shop:

You should have your Altima inspected by a qualified mechanic as soon as possible. While these issues might seem minor, worn suspension components can compromise steering, handling, and braking, potentially leading to unsafe driving conditions or accelerated wear on other parts. A mechanic will typically:

  • Visually inspect all front suspension components for signs of wear, tears, or looseness.
  • Perform a 'shake test' to check for play in ball joints, tie rods, and wheel bearings.
  • Listen for the noise during a test drive to pinpoint its origin.

Replacing worn components will restore your Altima's ride quality and safety. Costs can vary depending on which components need replacement and whether you opt for OEM or aftermarket parts.
