Well High gear at 25mph would make a noise in my MT if I ever decided to do that. It would probably sound very angry if I tried to do that. The engine isn't really designed to handle that much torque at such a low rpm.

At that low of speed driveshaft balance would not come into play.

Where is the noise coming from exactly?

Point is, the noise isn't normal and it's 100% related to the diff install.

I'm not really worried but it's an annoyance I would like to get rid off.
