Why is my car making a clacking sound when I put it in reverse?

Answer by  SyNtEcH (108)

If its a front wheel drive car I am willing to bet its the CV axle. Its the part that attaches to your transmission to your hub/wheel. To test it Turn to the left all the way and then reverse if it gets louder then its your cv. Makes sure you replace if its making noises Before it goes.

It is most likely a transmission or driveshaft problem. Check your transmission fluid and check for slack in your driveshaft specifically when in reverse. A clacking sound can come from the slack. You may also want to have a diagnostic test performed on your transmission if the other two items do not correct your problem.

There must be something wrong with the brakes or the tires or some sort. You should get it checked by a mechanic.

When the reverse gear teeth get worn out, they tend to generate a clacking sound. The recommended or typical solution would be to replace the reverse gear.

That sounds like you are having problems with the U-joints in your drive shaft are going out. This is something that is easy to check, but not by yourself.
