was thinking of changing the transmission, transfer case and diff oils now that I’m at 30k miles as preventative maintence. Oils are cheap, unseen water intrusion or other issues leading to failure is not.

Transfer case and diff oil should be relatively straightforward, but you may want to research changing fluid in the transmission. Often times with modern transmissions that fluid has to be up to temperature and exchanged using a special machine at the dealer to achieve the correct level of fluid since there is often no transmission dipstick. There is also likely a screen on the pickup for the transmission pan that is changed when the fluid is changed.

Not when most places do the trans service!! This is why I hate the invention of the flush machine. It's nice to get most all of fluid out but you can run more through until you have replaced all same as they do....BUT it is MUCH MORE important to change filter and clan pan.
They made the machine to make it easier for them, THEN charge more and act like it is a better service.

Still pretty hard to get the fluid out of the torque converter by just dropping the transmission pan, so a combination of cleaning the pan/replacing the filter screen and then doing a full flush seems like it would be ideal to get all new fluid in the torque converter and still get the debris out of the transmission pan.

Few shop or quick lube places will do that though.

Most do it themselves after the jerks stopped putting drain plugs on converters. That was a big plus for fords.
Unhook one line going to rad and pump old out as you add new and get to all new, plus pan drop and filter.

The problem is there is no tranny dipstick (hehehe) to confirm tranny fluid level and no easy place to add the fluid. Last I saw the fill hole was on top of the tranny and difficult to get to.

Yes, I was going to mention in last post that it is a pain to keep adding fluid but you just have to rig a tube and a pump or run tube up and hook to bottles or gallon so you can squeeze in fairly quickly.
If I had a free flush machine use etc ok, but I'm not going to pay them 79.99 and way + to do hat I can do for the cost of fluid.
Some do the 2-3 frequent pan drops to approach 100 fluid change.
You never actually get 100% of all the old fluid out. You are diluting it though and can do estimates as many have done.
50% 1st time, then 2nd...etc pan drops are typically 4-6 qts on vehicles so you can do the math to see how far you want to go as it approaches 100% replacement.

Buy the dipstick tube that mounts on the firewall from Summit Racing, also change the pan to cast aluminum with a drain plug. There can't get any easier than that.

30k? Gonna flidh the brake fluif and replace your gorley filters too?

seriously, as a four Ford Expedition owner with only one transmission problem inside of warranty, I wouldn't start thinking about that for another 70,000 miles.

Wait 20k more miles and do your spark plugs then too.
I do all preventative maintenance that the factory suggests but at half their intervals.
Those are all synthetic fluids and will he just fine until 50k.
My plugs were pretty bad at 50k but you all have the new generation EB so may not be as bad.
I certainly wouldn’t go 100k as the factory suggests but 50k not an issue especially since stuff is cheap.
I do the oil and rotate my tires at 5k. Never even bothered looking at that oil life thing.
I’ll likely do my fuel filter in a couple weeks. Should have just done it with my 50k stuff.

I don't think our '16s have a serviceable fuel filter....

Interesting
NAPA, OReilly, and Rock Auto all list 2L2Z9155AB as the fuel filter part number.
Ford OEM lists nothing and says that part does not fit. So I guess your right. Kind of silly not having a servicable filter.

My 17 Expy only has 9,100 miles so far but at 10k I will be doing the following:

Fourth oil change - done at 1,000 miles, 2500 miles, 5,000 mile, now when I hit 10k miles
Drop trans pan, replace trans filter. Measure how much fluid came out and replace with same.
Brake fluid flushed at 5,000 miles, next at 10k miles.
Rear and center differential fluid

Fluids are cheap and they are the lifeblood of the moving components.

How incredibly wasteful. But hey, it's your 3rd gen rig.

To each is own. Do I over maintain my vehicles? Maybe, but fluids are cheap compared to engine and transmission repairs.

I will tell you that my last SUV was an 2005 Ford Excursion that I sold in 2018. I had her for 15 trouble free years and yes I over maintained her too. When I sold her book value was $17k but I got $28k because the truck was spotless and the person who bought it knew it was well maintained.

And the fact it was an Excursion.
No way an Expedition will ever pull that kind of value.

Hey, fair enough, that's a decent deal. But an Excursion isn't really an SUV, that's a truck. Which also isn't produced anymore and is obviously a workhorse and a half.

I do think that's kind of a waste but you know, if it makes you sleep better at night and feel better then it's your money. You really can't rationalize that you got so many miles out of it and were trouble free for 15 years simply because you did the maintenance. Tons of other people barely change the oil and get the same type of miles and lack of repairs needed out of them.
I have done both ways over the years and there's really very little difference. Taking care of the body and paint and the inside is completely different story though. You will certainly get a much higher resale value when you go to sell it. You should never trade a vehicle and because it doesn't matter they rip you off. But with the private owners you will have to show it to a few more people and hold out for your price but you will get more money.
Certain things we have to pay attention to other people's experience and go with what we know works. For instance it is becoming fairly common knowledge that clean oil makes the cam phasers on the three valves last longer. Unless I am mistaken here since I currently will not own one and I'm staying far away from them but the consensus seems to be you will have fewer problems if you change the oil regularly. On the old 2 valve it really didn't matter that much. People have complained about the small passages or at least commenting about the small passages since they started making Modular Fords and I'm telling you it's just not that big of a deal.
