Breaking in 3.73's

Well I got my true-track 3.73 diff in yesterday. I did one break in run, about 15 mins like the article says. At about 30-35 mph it begins to whine, so I tried to stay about 25mph. I just got done with the second break in run, about 30 mins at 25-30. It is still whining a little bit. Is this usual for the break in run? I hope I am breaking it in right...After it cools for 3 hours I am doing the final break in...hope it stops whining....

All Glory to God!
