I know they say the tolerances from the factory are good and usually wouldn't need a break in period oil change but I have done front and rear after 500 miles break in and it has worked for me so I plan to continue that tradition.
Also I always enjoy OG maintenance videos. It is relaxing lol.
I doesn't hurt to change the diff oil.Especially if you have been in water deep enough to cover the axle, water can get in.
"If you’re anything like me, you’re not going to want to sit there for hours waiting for your driveline to cool down before you get your hubs wet. As we said before, when the driveline gets hot, it vents air out … when it cools down, yep you guessed it, it sucks air back in; if your diffs are hot and the breather goes underwater, it is going to suck litres of water through the breather. In some cases, breathers have a one-way valve that closes when the pressure flips, and in this case that water can be sucked in through your axle or pinion seals."
