p { margin-bottom: 0.08in; } I have a 2002 XC70 that is making a noise that I suspect is a bad CV Joint. The car makes a noise that increases and decrease with acceleration and deceleration. The noise is clearly tied to the speed at which the tires rotate and not the actually RPM's of the engine. The noise get worse when you veer left, and goes away when you veer right. I originally thought it was an issue of tire ware because the front end was out of alignment again. I replaced the front tire and had it aligned. That did not stop the noise. The rear tires are fine. I suspect it is a CV Joint, but I can't find a Chiltons Manual for the car and I don't know how to determine for certain if that is the problem. Any suggestions would be appreciated.

 

Did you look at your axel and your CV joints? Are leaking and throwing grease? That is a tell tale sign you have trouble. They should not be leaking. If so, you will want to get them out and have them looked at. A lot of people will just replace the whole axel if that is your problem. Either way, check it first and see if it is throwing grease all over under there. Also, look for holes or tears in the boots that cover the joints. This is a common problem.
