#High #Mileage #Maintenance for the long term
I came across this great post from member nuclearn8 on the "Differential and Transfer Case Fluid Change" thread.
He mentions a laundry list of maintenance items one should look into. I quote him below
I have been doing some research myself. My '13 GX is sitting close to 175K. I want to keep this car around for a long while and I was putting together a list of items I can do that will add to the longevity of the car. I plan to chip away at this list every few weekends when I have time. I'm still compiling the list of items to check. I wanted to share it so you guys can add anything I missed or I don't need to bother with.
1. Oil change and filter (most obvious, but needs to be stated)
2. Engine Air Filter
3. Cabin Air Filter
4. Engine Coolant fluids
5. Anti-freeze flush
6. Power Steering fluid
7. Check serpentine belt
8. Clean fuel injectors
9. Check Spark plugs (mine seem to have been changed already)
10. Clean MAF Sensor
11. Clean Throttle Body
12. Differential Fluid
13. Transfer case fluid
14. Transmission fluid
15. Clean evaporator coil
16. Brake fluid flush and bleed
17. Chassis Lubrication. Lube drive shaft propeller? (as per nuclearn8 below)
18. Check for Open Service Bulletins
19. Clean smog sensor
20. , and install . Bonus, 21.
Mods for longevity:
1. Automatic Transmission Cooler
2. HD Transmission Valve Body Upgrade
3. Delete EGR? (still up for debate on the benefits, if any)
Any input from the board is appreciated.

Everything looks good.
There is no need to buy a magnetic drain plug for the TC. I verified this during my last change and documented it in that maintenance thread....
that being said, if you're dead set on spending money there is one option I am aware of, dimple magnet rare earth drain plugs. https://drainplugmagnets.com/cars/toyota-lexus/ but again this is a waste of money.
other items you may want to consider to help ease this and future maintenance and based on your mileage
- Converting to the metal engine oil filter cap and get a fumoto drain valve for the engine oil pan
- Getting the KAON front diff drain hex plug
- Skipping the pump/funnels and buy the Amsoil easy packs (no need for a pump) for the front and rear diffs and power steering (see below)
- Have you drained and refilled the transmission at all?
- Buy amsoil easy pack and do an extract and fill of the power steering reservoir for a week after it cools down from driving it once a day, see the maintenance link from the sticky
- apply some silver anti-seize on your skid plate bolts on reinstall
- get some fluid film and clean the sunroof glass gasket and paint mating surface
- lube your rear door latching mechanism
- Has the brake fluid been serviced at all (flushed and then bled?)
- Lube that drive (propeller) shaft while under her
- how's your serpentine belt? If original may want to have a good look with flashlight for evidence of dryrotting
- spark plugs original?
- clean your MAF sensor (just get some CRC spray and spray it down after removing it)
- run some fuel system cleaner thru with the new gas fillup

Yes, I definitely saw that one. But it was almost an overload of information. It covers the gamut. Which is great.
I was hoping to specifically cover the stuff you would want to do to make this car last as long as possible. This model came out in 2010, so I am sure a lot of owners are getting into and well past 200k on the odo. I searched the forum and didn't find anything on this specific subject, So I'm hoping a thread on this topic might be helpful to others as well.
I'm sure there is a ton of stuff that can be improved to make this car even better. I also wouldn't doubt there are plenty of maintenance items I haven't even thought of.

Theres not much you can do on the GX to improve longevity...its been on the market for a decade, so if there was an issue, we`d see forum posts or TSBs/Recalls from Lexus after their data analysis on part failures.
Besides the transmission I assume nothing else was problematic on your new acquisition?

Actually 4L "without" CDL locked can be used on dry pavement. It won't hurt anything. As long as you are going straight locking and unlocking CDL should be fine too. You just don't want to be turning vehicle on dry pavement with CDL "locked" as you will get driveline/axle binding.
To be extra safe though soft terrain would mitigate all concerns.

Not sure the difference between 4 and 5 on your list... either way a properly maintained vehicle likely will only last as long as it doesnt rust away, for longevity, one of the best things you can do is fluid film the undercarriage completely... anything that heats up (brake calipers, rotors, engine, tranny, tc, exhaust) try to avoid... Make sure to fluid film your kdss control box (bolted to drivers side frame rail), front LCA alignment bolts and tabs, suspension bolts and nuts frame (inside frame as well with aerosol wand extension) skid plates both sides... anti seize all the skid plate bolts...

You could try to go after the PCV valve. Many here including myself have tried but backed out. I didn't really feel like pulling the intake plenum off.

At that mileage and in that climate, I would replace the radiator if it hasn't been done already. While replacing the radiator, I'd replace both hoses and clamps, the water pump, serp belt, tension, pulley, and the fan clutch. Those parts aren't really all that expensive for OEM, and you'll have good piece of mind after doing them...
Check your AC charge level also...
