My car is at 13K with a weird noise. Well after having a wheel alignment done from the dealer with the Canuck Motorsports drop 3 weeks ago, I get this weird noise coming from my passenger side. It sounds like air is coming through on the passenger side like a plastic noise like someone is taking an air hose in the air and swinging it to make it louder. I don't get any grinding noise when swerving or any vibrations. I thought the dealer messed up the wheel alignment and they told me it's the tires that is causing that vibration do to feathering, but later took it to a local shop that has a higher rep on wheel alignment did a inspection. The mechanic checked both wheel bearings with no abnormal noise, CV joints, and the alignment from the dealer is fine. He is guessing it could be the tranny because I'm equipped with OTTP Stage 1 mount. So I don't know. Anyone have this issue?

 

The tranny noise def gets louder with the mounts. I went S1 then S2 a few weeks later. More gear and bearing noise transmitted through the stiffer mounts.

 

That was the last thing I was thinking. I thought it was a bad wheel bearing or a loose hub on the strut. So I'm guessing my conclusion after the springs have settled and the trans mount too is probably why I'm hearing that weird noise like an extra cylinder was pushing in extra air in going 35-40mph. oh well, I'll live with it.
