So a 2WD RX has front transfer case fluid that needs to be changed? At what increment?

Vehicle maintenance and occasional repairs are usually much cheaper than new car payments.

Everyone will have different opinions on the maintenance intervals when you get outside what is noted in the Owner's Manual. My thoughts:

Transmission Fluid -- drain and fill every 30K (Toyota T-IV)
Front Transfer Case and Rear Differential -- replace every 30K (synthetic)
Coolant -- since this is long-life I would replace when doing the water pump at 90K
Power Steering Fluid -- once a year pump out the reservoir and add clean fluid (Mobil 1 ATF)
Brake Fluid -- 2 YR
Cabin Filter -- Yearly. I gently vacuum it each quarter to remove visible dirt.

So, yes it is correct in that there is no traditional power steering fluid in your RX. Rather, it uses a DEXRON II/III ATF. I picked up a cheaper bottle of fluid first to use while I was cleaning out the what was in the system. Would pump out the reservoir and add back clean fluid every couple of months. Once the system was cleaned out for the most part I started using Mobil 1 ATF and change it out much less frequently now.
