Hello I am new to this site and i am having a problem with my 2007 Volvo s40 t5 awd automatic. I have a vibration at around 2000rpm if I downshift it goes away so I took to shop and they checked everything out and said it needed shocks struts and end links. I was thinking the cvs where bad and they told me they are fine. Any help with this I know most of the time they say if the boot isn't torn the cv is good but I can't figure out what is causing the vibration any help would be great thanks in advance
