Clicking Noise When Turning: What It Means and What to Do
A rhythmic clicking or popping sound that shows up when you turn the steering wheel, especially during sharper turns while accelerating, is most often a worn outer CV (constant velocity) joint on a front-wheel-drive or all-wheel-drive car. It typically starts after the rubber boot that protects the joint tears, letting grease escape and dirt get in, which wears out the internal bearings. The click usually gets louder and more obvious the tighter you turn. Caught early it's a straightforward axle repair, but a badly worn joint can eventually fail.
Common causes
- 1
Worn outer CV joint
The classic cause: a clicking or popping that appears during tight turns and accelerating. Worn ball bearings inside the joint click as they grind against their tracks. This is the most likely culprit by far.
- 2
Torn CV boot with lost grease
A cracked or split rubber boot lets the protective grease fling out and dirt in. You may see grease sprayed on the inside of the wheel, brake parts, or the bottom of the shock. Once the joint runs dry it wears quickly.
- 3
Worn or loose suspension components
A failing ball joint, worn tie rod end, or loose strut mount can also click or pop during turns, since they move under steering load. These also affect handling and tire wear.
- 4
Worn sway bar links or bushings
Loose stabilizer (sway) bar links can click or clunk as the suspension loads up in a turn, sometimes mimicking a CV joint noise.
- 5
Loose or damaged wheel components
A loose wheel bearing, brake hardware, or even a loose lug can occasionally produce a clicking sound while cornering, though this is less common than a CV joint.
What to do
A clicking CV joint isn't an immediate emergency, but it will get worse and a severely worn axle can fail and leave you stranded, so schedule an inspection soon. You can test it yourself by driving slow, tight circles in an empty parking lot in both directions and listening, and by checking for torn boots and slung grease around the wheels. Once a CV joint clicks consistently, the axle usually needs replacing rather than just the boot.
