What gear lube and weight? Did you add the friction modifer?

Changed mine at 4050 miles. Magnets were full. Zoom in on pic and see the thikness of iron wear. Oil was jet black, thought it was FM, no it was ferrous meter too, xl-3 is green. Amazing how much wear. The 85 weight from factory was more viscous than anticipated. Surprisingly the 90 weight runs cooler??Unless you're doing something very unique, I'd leave things as-is and wait.
The factory fill should support you just fine. No one has reported issues with the oil or pumpkin. No one has reported any advantages if replacing so early. While the internals of the diff are seating and wearing, the conditions are not the same as within an engine (more extreme heat cycles, exposure to gases and fuel).
IF you think you have a problem, I'd go directly to the dealer and discuss, while under warranty. Otherwise, I wouldn't touch it.
In the mean time, sure, read up on what others have done, products they've used, tools they've needed.
FWIW, I've got a 3.73 Torsen. Other than checking for leaks soon after taking receipt and occasionally during break-in, I've never touched it. Works flawlessly.

I used Lucas Syn. gear oil, 75w140 and Ford friction modifier when changing the gear oil in my Torsen T-2R. Owner's manual list it as well for the S650.torsen diffs do not require the use of friction modifier.
Try jpgsSorry pics won't post. Bottom line change fluid especially since it only holds 1.6 it's and it is so cheap and easy to do.

Why 75w140 over a 75w85 or 75w90?I used Lucas Syn. gear oil, 75w140 and Ford friction modifier when changing the gear oil in my Torsen T-2R. Owner's manual list it as well for the S650.
