Changing Diff fluid after gear change brake in period?

So I heard from some people I should change the diff fluid after 500 to 1000 miles of my gears being changed? Wanted to make sure this is correct? I just installed Yukon gears about 500 miles ago and will change the fluids again if I need too, I was thinking about getting some new Diff covers when I'm at it also. Thanks

This ^. Don't be alarmed at the dark color, or if there's some fluff on the magnet, quite normal. I did mine again at 1500 miles just for comfort.

Did you pull your covers both time?

500 long miles after the break-in period. Check your patterns and look through the fine particulates, a combination of phosphate coating and metal wear, which is normal. Chunks and pieces are not normal! Great chance for new diff covers, if you hit water a lot you should check/change fluid often - lubelocker gaskets make it easy and they pay themselves off after a couple changes/inspections.
