I would take it real easy until after the 500 miles. Heat cycles were recommended. Granted you had to take the highway home after the install, just like me, but I was told to keep the speed around 50mph and not to push it. Punching it with your gear just installed isn't such a great idea.
I've heard of people just rampaging after a new gear install (on fox bodies) and had no issues but it's not guaranteed they won't get botched or whine after that.

so the gears can 'lap' together. Once these contact patches are established
(you hope they are in the middle of the teeth) the rear end can then
handle the torque the engine can produce (up to a certain level).
If the gears are incorrectly meshed and the contact patches wear
in on the heel or the toe of the teeth, the wear is there for life as well
as the whine... Even if the gears are reinstalled properly at a later date.
New gears have such a small contact patch until the gears 'lap' together
and the contact patch increases. This 'lapping' action stops once the
contact patch is large enough to handle the touque of the engine.
But that second gear spin will cost you somewhere.
Dont open those presents up until Christmas.
You were the one with the tape in the middle of the night, right...???

It appears that you are not following their advice...
And when they told you to let the 'bearing break in',
what exactly did you interpret that to mean exactly?
Bearings need no 'breaking in'.
The ring gear teeth need to 'break in' to the pinion teeth if
anything. How knowlegable are these gear installers anyhow?
This makes me leary as to the formation of the rear end whine
in your near future. You dont even mention the brand of
gears or the maker of the new bearings and seals used.
Tawain overseas or quality USA made components?

All REPUTABLE shops who have done gears before, tell you to take it easy for the first 500 miles or so with the gears. Whether its true or not I'm sure most agree that its good to go easy with them for long term reliability.
