Great to be here.

I just bought a used 2015 Frontier 4WD crew cab with about 36,000 miles. I drove my previous truck 17 years and I’m planning to keep this one too. Don’t know how this truck was maintained previously so I’m considering the following and hoping someone will advise me if I’m making a mistake.

1. Change engine oil and filter. (May try Mobil 1 synthetic.)
2. Change air filter.
3. Change cabin filter.
4. Replace engine coolant.
5. Change automatic transmission fluid. (Looks like this is a flush instead of a filter change.)
6. Change transfer case fluid.
7. Change front differential oil.
8. Change rear differential oil.

Am I missing anything important?

Yes I know this is probably overkill. I know on some vehicles it’s better to leave things alone. Some of this will probably be done by the local Nissan dealer.

Comments welcome.

I bought mine a few months ago with the same mileage. I did pretty much that at 40,000 other than just inspecting the air filters - was clear they had been changed recently so I didn't change them again.

If you do the cabin air read the posts on opening the cover without breaking the tabs - mine were broke already so I knew it had been changed.

Also read the posts on transmission drain and fill if you're doing it yourself.

Enjoy the truck.

I personally would not do 4-8 unless I see signs of problems. I bought mine with 97k. Tested the coolant and it's fine. Put some Pennzoil synthetic and seafoam in the engine and I'm about to change that out to a better oil when I hit 100k this weekend. Checked the spark plugs. The air filter was fine but it got changed anyway because I added an AirAid system. the cabin filters were dirty so I replaced those. Added the axle vent.

My truck was obviously used off-road and I'm about to hit 100k so I'm doing the differentials next month and i need to do the clutch so I'll be changing transmission, transfer case, clutch, and brake fluids at that time.

Anyway, my point being I would follow the normal service schedule with the exception of obvious issues or suspected potential issues, such as signs of hard off road use, extreme lift and tires, etc.

As stated above just do a drain and fill on the transmission, if the fluid is very dirty do it a couple of times. No flush.

Change the brake fluid, should be done every 3 years or so.

In case you haven't discovered it yet, there are two different types of rear differentials and they take different fluids. There is a good thread on changing all the fluids.

check the air in the tires...

where you from?
Day #1 was a cool morning and the TPMS light came on. All the tires were somewhat low so I guess this was a good thing.

East coast NC, USA.

Thanks for all the advice. Exactly what I'm looking for!

Changing engine coolant at 36,000 miles is throwing your money away. A 2015 would have Nissan Blue long-life coolant, which is good for 10-years or 135,000 miles, whichever comes first.
The automatic transmission fluid is synthetic, so flushing it is really not necessary. I wouldn't do anything more than a drain and fill (personally, I wouldn't even do that until 60,000 miles). Just make sure you use automatic transmission fluid that is compatible with NissanMatic Type "J" or "S" ATF (Valvoline Maxlife full-synthetic ATF, Castrol Transmax Multi-import ATF, to name a couple that are).
I, personally, would put off the transfer case and diffs until 60,000 miles as well.
At 36,000 miles, I would change the oil and filter, replace the engine air filter and cabin air filters, rotate the tires as needed and adjust pressures and check the brakes. I would check the other fluids and top off as needed and leave the rest alone.

Absolutely NOTHING on your list will benefit from being done by a dealer.

You'll just be throwing your money away.

If you don't feel like doing some items yourself, find a good independent shop instead.
