Good idea on the engine mounts!! I’ll definitely do that, I’m also thinking since the n62 motor has that stupid alternator bracket seal/gasket issue, while I’m in there I might as well change that.
Regarding the diff oil, I just turned the drivers side wheel and I have access to the hex fill plug, I did notice that it has a green o-ring, so I’ll see if I can get those too. I’ll also change out the rear diff and transfer case fluid while I’m there.
So the shopping list for me so far is;
Alternator gasket
Both axels (just in case)
Diff 4:10 ratio
Both sides output shaft seals
Engine mounts
75W90 gear oil (I have a transfer pump if needed)
Hex fill/drain bolts or o-rings for front and rear diffs
Would there be anything else that I need while I’m there? Thanks!!

I keep forgetting that you have an N62. The Bentley procedures are the same, but take it all with a grain of salt!
My plugs didn't have o-rings, so I ordered new plugs. I wasn't sure if I could just throw a generic crush washer on them. I read that there are different torques for o ring and non-o ring plugs, and my new ones came with o rings.
The alternator bracket is a very good idea, since that causes the N62 guys no shortage of heart ache it seems. Having the stiffener plate off, the diff out and the sub frame down a bit opens up a lot of inspection space, so in addition to the oil pipe o-rings, I'd do all your power steering crush washers, inspect all the heater hoses that you can see (assuming any are routed into the basement of the engine bay like one is on the M62 cars), and if you pull the fan and shroud to make more room to get the motor up without damaging your radiator by mistake, I'd perhaps replace any lower coolant hoses since they are cheap and can be tough to get off without the extra space.
As far as the splines go, I don't get the sense they are a problem with the N62 cars, and yours are newer anyway. So if they look good then I'd leave well enough alone. Maybe some N62 guys can weigh in. Having the diff off would certainly make installing longer splines "easier" though.
