If you want to to it correctly follow your owners manual. I just did ours with our annual oil change and generator service this year. It was due according to my owners manual. Three years old and 5100 miles ( I need more time off work).

Otherwise as you see, you're going to get a bunch of answers.

a total waste of gear oil,time and money but as we say to each their own gear oil does not age. it can get metal from wear and moisture from temp changes etc eventually but that takes 50-100 thousand miles
small diffs require sooner changes than large diffs like Diesel pushers

Depends on the differential and fluid used. MY Dana 80 call for changing the 75W140 synthetic at 100,000 miles.
Follow your owners manual.

I did my Ford chassis at 50k miles.

Have not yet and do not plan on anytime soon... topped it off recently. Have owned since almost new.

I purchased mine used with no service records and it was 16 years old.
Changed all the fluids now I have a starting point.

When I bought it used. Won't worry about it again. Did thee oil in the front hubs also.
