My 2014 CR-V was making a noise which appeared to be related to engine speed, not wheel speed. A couple of other shops were unable to identify the noise so I thought Honda might recognize it, if it was common on other similar models. I asked if I could go along for the test ride to make sure that you were analyzing the right noise. I was told that was normally against policy but "we will see". A half hour later, I was told my car was ready to go. What about my ride-along?? The person who returned my keys (and was dressed in a mechanic's uniform) read the notes from the mechanic to me but clearly didn't understand what he was reading. You had identified a bad hanger bearing on the drive shaft. "But", I asked. "isn't a hanger bearing noise related to wheel speed, not engine speed?" Your employee didn't know. The mechanic's notes suggested that I start by changing the drive shaft, $2979 plus labour and taxes for nearly $4000, and then see if that would fix the problem. I felt this was very poor value for the $200 (including $22 in environmental and shop supplies??) this advice cost me. However, to give the Devil his due, it turns out that your analysis was correct.
