Diff Oil Change
My 2010 GL 350 with 115k Miles and was thinking of changing front / rear / center diff/ transfer case. Now I know some might say it can do more harm than good after a certain mileage. Just wanted to hear from people that changed at high mileage or has high mileage without changing with their experience.

I changed all three at 75K miles and 11 years
The differential gear oil looked brand new.
The transfer case ATF looked a little less than new.
Note that both fill and drain plugs on the differentials are sealed with O-rings, not washers. Buy new plugs, they come with O-rings attached.
The two plugs on the transfer case will require new crush washers.
You're going to have to pump the new fluids in, as gravity feed can't happen.
