Question about changing gear oil after a R&P swap

Pertaining to giving the differential(s?) fresh gear oil after the gear break-in, can I just pump it out and put in new oil? Or since there might be metal flakes I need to unbolt the cover and let it drain that way? Sounds like a stupid question.

Many "quick lube shops" just pump/suck out the old. I would pull the cover though to get it all out and do a inspect.

It will work either way.

It would be best to pop the covers and look at the gears for any unusual break in wear or other anomalies.

You're gonna want to check and wipe any metal flakes out.

I have to do that to mine here shortly. I just got 4.10's put in and have to do this in about 250 more miles. I am going to remove the covers.

I was wondering this after I changed gears a few months ago. I pumped out all the fluid first. Then I popped off the cover and checked what I would have left behind. There wasn't a a significant amount of metal found in either. After removing the cover there was definitely some metal left on the cover and diff. I don't know if it was enough to cause a problem or not but I'm glad I did. If you get lube lockers it takes some of the work out of disassembly and reassembly.
