Gear Oil and new gears

I upgraded my differential gears about 500 miles ago to 4.88 from 3.21. I have driven it as recommended by the mechanic but am curious when you guys change the gear oil after a gear swap. Do you do the break in then change or just go into the normal maintenance pattern from the start. Yes I have searched the forum for the answer and can't seem to find the answer.

I did a 500 mile break in, replaced the oil and then went to a standard maintenance pattern.

New gears will give off some shavings and it is best to get them out as soon as the break in period is done.

Exactly. While establishing a wear pattern they will contaminant the oil with fine metal shavings. Leaving the break in oil in for a long period of time is a very bad idea and has lead to bearing failure in more then one diff that I have seen.

I agree 100% that diff fluid should be changed early after a regear but kind of funny that it is not recommended on gears from the factory.

It should be. My rear diff. fluid was definitely chunky after only 4000 or so miles.
