Toyota Sienta CV Joint Noise — Diagnosis & Replacement
A clicking noise when turning is the classic CV joint warning. Catching a torn boot early can save the joint and avoid a full driveshaft replacement.
CV (constant velocity) joints connect the driveshaft to the wheels, allowing power to be transmitted at an angle as the suspension moves. In Malaysia, CV joints take a beating from speed bumps (bukit unta), potholes, and high mileage — especially on front-wheel-drive cars.
The classic clicking noise — what it means
- Clicking or popping noise when turning with acceleration — usually the outer CV joint
- Clunking noise on acceleration or deceleration in a straight line — inner CV joint or driveshaft coupling
- Vibration felt through the steering wheel or floor at certain speeds
- Grease spray inside the wheel arch — torn CV boot is the cause
Boot replacement vs full joint replacement
If caught early (torn boot but joint still smooth with no noise), a boot replacement can save the joint per boot including grease repack. If the joint itself is already clicking or rough, full replacement is needed per joint depending on the car.
