Ok, first weird noise... whenever I take off, it feels like my rear end kind of rumbles or knocks a little bit, then its fine again. I think theres some play in the driveshaft, would that cause anyhting like that? 2nd, when i hit 3rd gear (sm465) it kinda makes a windy whining sound... like there wind blowing in the rear tailgate.. but if i put in the clutch or let off gas, it goes away? I just noticed the 2nd noise tonight, but the first problem has been around for a while. Thanks!
