I hear a clunking sound from my front wheel when I make a turn. What could be the problem?
Express Car Care Answer: One possible cause of the problem is a worn axle. Front-wheel drive vehicles have axles that transfer power from the transmission to your front wheels. There is one for each front wheel. These axles are called constant velocity axles or CV axles for short. Rear-wheel drive vehicles have axles that are in back and run between the differential and the rear wheels. Then there are all-wheel drive vehicles which have an axle at each wheel.
When a front CV axle goes bad, it will make a clunking noise as you make a slow turn. When a rear axle goes bad, the clunking or moaning sound will be in the back. No, there really isn’t any preventative maintenance you can have performed to make your axles last longer, but you can have them inspected from time to time to see if a problem such as a leaking seal or torn protective boot has arisen. Sometimes finding the problem early will make the repair easier and less costly.
Of course, axles do wear out and need to be replaced. This is dangerous and should not be put off by drivers, because a severely worn axle can seize up causing damage to your transmission or other components. This could even lead to an accident for any driver who ignores a worn axle.
If you suspect an axle problem, have it looked at right away. Ask your friendly and knowledgeable service adviser at Express Car Care if it’s time for your axle to be replaced.
