Clicking Noise When Turning? Here's What It Could Be

A repetitive clicking or popping noise that only appears when you're turning is a very distinct symptom. It can be concerning, and for good reason—it often points to a problem with the parts responsible for delivering power to your wheels as they turn. Let's diagnose what that sound could be.

1. Bad CV Joint (Most Common Cause)

The most frequent culprit for a clicking noise when turning is a failing Constant Velocity (CV) joint. CV joints are part of the drive axle (or driveshaft). In front-wheel drive cars, these joints are what allow the front wheels to receive power from the transmission while also being able to turn and move up and down with the suspension.

Each drive axle has two CV joints: an inner joint and an outer joint. The outer joint is the one that most often fails. It's protected by a flexible rubber boot filled with grease. If this boot tears (due to age or road debris), the grease leaks out and dirt gets in, causing the joint to wear out and start clicking when you turn.

2. Worn Strut Mount or Bearing

The top of your car's struts (part of the suspension) are connected to the car's body via a strut mount, which often contains a bearing. This allows the strut assembly to pivot when you turn the steering wheel. If the bearing wears out, it can bind and release, creating a popping or clicking sound as you turn.

3. Failing Tie Rod Ends

Tie rod ends connect your steering rack to your steering knuckles (where the wheels are mounted). They are crucial for steering control. When they wear out, they can become loose, which can sometimes cause a clunking or clicking sound as the steering load shifts during a turn.

What To Do Next

A clicking noise when turning, especially if it's a CV joint, is a serious safety concern. If a CV joint fails completely while driving, you will lose power to that wheel, and it can cause a loss of control. **Do not ignore this symptom.**

• Visually Inspect (If Safe): Look at the rubber boots on the axles behind your front wheels. If you see one that is torn or covered in grease, you've likely found the problem.
• Schedule an Inspection Immediately: A mechanic can quickly diagnose a bad CV joint or other suspension/steering issue. It's often diagnosed by turning the wheel while the car is on a lift and checking for play in the components.
• Ask the Right Questions: When you go to the mechanic, ask: "I hear a clicking when I turn; can you inspect my CV axles and boots? While you're there, could you also check for play in the tie rod ends and strut mounts?"
