100k maintenance
I bought a '05 GX last fall with 93k miles on it. It now has 102k. I want the vehicle to last me many years so want to get it buttoned up. I checked My Lexus for service history. No timing belt maint listed.
A few questions:
Should I trust a non Toyota very capable repair shop that I trust to do the TB/WP/Pulleys/Tensioners? (they all seem to be working fine...just thought maybe i should get it done)(not sure how hard this maint is to a non-toyota tech)
Everything seems to be working properly on the vehicle. With that said... as stated above I want this vehicle to last. Looking at the maint schedule... it mentions lubricating the drive shaft often.
Should I do this to make sure it's A-OK?
Any other maintenance recommended as the history on My Lexus didn't show anything since 65k. Transfer case fluid?

Yes, get the timing belt done. Don't delay. Consider changing the thermostat at this age.
The 2UZ motor was used in the Tundra and also I think in the Sequoia, so any experienced Toyota tech can work on it. So far as a non-Toyota shop - no guarantees (no guarantees with a Toyota/Lexus shop either, but chances of a good job are higher I think)
4x4 service is about every 30k. That'll be new fluids for the front & rear differentials, and the transfer case. Plus grease for the zerk fittings on the driveshafts. Use any good-quality commercial fluid (Castrol, Mobil-1, etc) that meets the spec.
Toyota says the transmission is sealed for life, but that's bogus. Pick a service interval you're comfortable with (30k, 50k, etc) and do a drain + fill on it. This will replace about 1/4 to 1/3 of the fluid. Use only Toyota brand fluid, and get the work done at a shop that knows that temperature is important when setting the fluid level.
Change the coolant every 3 years. Use Toyota-brand coolant. Change the oil every 5k miles. Use any good quality commercial oil that meets the spec.
Change the brake fluid every 3 years, or 2 years if you live near the ocean or very large lake (brake fluid is hygroscopic and picks up humidity). Use any good-quality commercial fluid that meets the spec.
Be expecting to replace the radiator soon (look for red crystals around the plastic end-caps).

I’ve had 2 GX’s, total 250K miles...only change coolant when I did timing belt with water pump..,the oem coolant is good for a long time. Changed drive train fluids to amsoil synthetic at about 50K...that should get me another 100K, if we are still using internal combustion engines by then...I grease drive line once a year on my 09, on my 05 with older shaft I did it every 5k...truck is pretty bullet proof...adaptive suspension is the biggest problem with these trucks...to complex for a truck...
