Why is diffential break-in so important?
I just installed a new DTE 4.10 differential in my car, and I'm in the middle of their required 300 mile easy break-in, and all this easy driving's got me wondering what's different about these aftermarket gears that requires all this extra attention.
Do the OEM manufacturers do any type of break-in on a new differential before the car is delivered? It seems like most new vehichles get test driven hard, and yet I've never heard of one failing. I'm going to do the full break-in, because it was too much work changing the gears to take a chance, but I gotta wonder...
Is this new differential any different than the thousands of others on the new car lots?

Oversimplified...
Your also not comparing a stock differential to a stock-type differential either... When you step into the realm of aftermarket performance and the extreme environment that most of those parts see, it's very easy to understand that one must give any of these parts additional break-in time so that can live up to the added abuses that their subjected to with the increased power output current engine combinations typically produce. Not to mention the MUCH tighter internal tolerances they have as compared to the relative sloppy build of the stock assemblies....
Don't confuse added break-in requirements with weaker durability..... Step back and look at the big picture as a whole and compare apples to apples.

Second, the differential is built to tighter tolerances, so it requires more miles/time to wear in.
Thanks for the clarification!
