    Alright, finally got a video for you with my phone. Managed to get the whine recorded. Sorry about the focus; it just didn't want to focus, but you can get a general idea of the speed despite the blurriness. It does this whine thing between 55-63 or so when you are 'light' on the throttle or decelerating. It really isn't bad and whenever I ask my passengers if they "hear that", they never know what I'm talking about, so it is very easily drowned out. I personally like the sound!



    It doesn't whine like that when you are a little heavier on the throttle nor does it do it at any speed above 65 that I've noticed. This is the only range I've noticed that whine on. I've had it up to about 120 on the track and never noticed it there either, though my exhaust and intake might have drowned it out.

    Cool, thanks for the video, and thanks for hitting the turn signal for reference. I'm sure I can live with that.

    I purchased the set of AKG diff bushings. Will be installing them in the next week or two. Just need to find a place to rent the tools.

    Are you subframe bushings still the factory rubber? Or did you ever drop the subframe and replace those 4 bushings as well?

    Subframe bushings are OE. 228k miles and they're just fine. They rarely need to be replaced.

    Glad to hear. Is your sub-floor reinforced with plates or structural foam?
    Just wondering if the poly diff bushings will cause any other issues.
