VIBRATION NOISE

[H3.007]

Do either of you have an aircharger system installed? I had a very bad vibration around 900 RPMs until just recently. I found that my aircharger bracket bolt and nut, forward most on the passneger side fender well, had vibrated loose. Also, the bracket attachment to the block also was loose. Tightened both and the noise is gone. I think I will install rubber bushings when the weather calms a bit and perhaps some LokTite.

I have always had a very minor vibration in the dash but only at very high RPMs (like when passing) and this is infrequent enough to be an issue.

ah...the wonderful H3 noises! The only noise I have now is one that sounds like my windshield is about to explode when I drive 70+ mph. Wonder if I should be worried...

Just do 80MPH. That way the sound will go away

yeah the trim on the outside of my passengar A-pillar vibrates pretty bad when its windy or im going 70 or more. The dealer said theyll fix it but they are just gonna put some sealant between it and the glass and i dont think that should be required so i havent decided yet if ill get it fixed.
