I decided to change the fluid in the differential due to a little gear whine at certain mph. Whenever installing new gears in a car/truck, after 1000mi its always advised to change the fluid after break in, so why not on a new car as well. It certainly can't hurt and some folks have had good luck quieting their gears down after changing the fluid so lets give it a whirl. Sorry for the background noise, my Zebra finch was very chatty this morning, hope its not too annoying. :)
