Quick Answer

Some of the signs that indicate a need to change a vehicle's CV joints include a growling or humming noise, clicking or popping sounds while making turns, and clunking sounds while shifting to reverse gear, according to Samarins.com.

A growling noise sometimes results from inadequate lubrication in the inner or the outer CV joint, as Samarins.com notes, but damaged wheel bearings and bad bearings of same-length halfshaft transaxles are more likely causes of the noise. Replacing them is often the best way to solve the problem.

In most cases, popping or clicking sounds produced when making turns indicates a faulty outer CV joint. Individuals can verify this by shifting to reverse gear and cranking the steering wheel to one side while reversing the vehicle in a circle. A popping sound gets louder only when the joint or the shaft assembly has a problem and needs replacement, as Samarins.com explains.

A clunking sound when accelerating, decelerating or when making a transaxle shift to drive is a problem that results from excessive play in the inner joints of FWD applications or the outer joints in RWD suspensions. The clunking sound can also result from driveshaft CV joints, as Samarins.com reports, and the clunking sound is similar to the excessive backlash from differential gears.
