Clicking Noise When Turning
A clicking noise when turning is the classic sign of a worn CV axle joint. The constant-velocity joint transfers power to the front wheels through the full range of steering motion — when the joint's grease dries out and the ball bearings wear, it clicks loudly under load during turns.
Can I Drive?
Yes, but with urgency. A clicking noise when turning means the CV joint is worn but still functional. A joint with a torn boot loses grease rapidly and will fail completely — usually without warning. Failure during a turn at speed is dangerous. Replace within 2–4 weeks.
Most Likely Causes
- 1
Worn outer CV joint
The outer CV joint is the most common cause of clicking noise when turning. Six ball bearings in a cage carry torque through the steering angle — as they wear, they click distinctly when the joint is loaded at an angle.
Click when turning left = right CV axle. Click when turning right = left CV axle.

Torn CV boot
The rubber boot keeps grease in and road grit out. Once torn, the joint dries out and dirt acts as an abrasive. The clicking noise when turning develops rapidly after boot failure — replacing the boot alone only helps if the joint isn't yet worn.
Inspect the inner fender/wheel well for black grease splatter — the telltale sign of a torn boot.

Worn inner CV joint
Inner CV joints produce a clunking or vibration during acceleration rather than a sharp click when turning. If the noise appears when pulling away from a stop or accelerating uphill, the inner joint may be worn.
Less common than outer joint failure but possible on high-mileage vehicles.
How to Diagnose It
- 1
Turn the wheel to full lock in a parking lot and drive slowly in a tight circle. The clicking noise when turning will be loudest at full lock — this confirms a CV axle issue. Try both directions to identify which side is affected.
- 2
Inspect the CV boots visually without lifting the car. Look into the wheel well with a flashlight. A cracked, torn, or missing boot with grease splattered on nearby surfaces confirms the boot has failed.
- 3
Check wheel lug nuts first — loose lug nuts can produce a similar clicking noise when turning. Torque to spec (usually 80–100 ft-lbs) before spending money on a CV axle.
How to Fix It
Worn outer CV joint
Replacing the entire CV axle shaft is more practical than rebuilding the joint alone. Remanufactured axles cost $80–$200 and the swap takes 1–2 hours. Remove the axle nut, disconnect the lower ball joint or strut, and pull the axle from the hub and transmission.
Torn CV boot
If the clicking noise when turning hasn't started yet, replacing only the boot ($20–$40 in parts) saves the joint. Once clicking begins, the joint is worn and needs the full axle replacement.

Mistakes to Avoid
- Don't replace only the boot if clicking has already begun — the joint is worn and will fail.
- Don't over-torque the axle nut — most require 150–200 ft-lbs, which needs an impact wrench or breaker bar.
- Don't reuse the old axle nut — it's a one-time-use torque prevailing nut on most vehicles.
