I had the dealer install a set of FRPP 4.10 gears into my '11 GT last week. There was a bit of vibration, which I figured was the driveshaft not being properly bolted back in it's indexed location. Well, sure enough, we put it on the lift, and it's off 2 bolt holes. So, we line it back up, and go for a spin. The vibration is just about gone, but, still just a tad bit between 50-55mph. It's more noticeable during deceleration, but, it will vibrate if you hold steady speed at around 55mph. There's also some vibration over 80mph or so..
What do you guys think? Is there anything else that could be causing this?
