With a new rear end you don't want to thrash the car right away kinda like the break in period, but especially avoid driving at constant speeds for the first 1500 miles. Doing so will likely score the ring/pinion and you'll end up with a groan coming from the rear end. After that, don't be afraid to push it!

That's what I was thinking, I dont think it's a common issue. Just bad luck. While I wouldn't suggest that the tech who changed the oil was incompetent, I do bring it up as a variable when they mentioned the track numbers on the window.
Ditto on the diff break in. I'll baby her all over again for the first 1500 miles like the original break in. Thanks.
