Great thread.
You're supposed to change the diff fluid more often if you tow a lot, I don't know where I read this.
This is of course a cheap DIY.
Even if you don't tow and get all your service done at a dealer, make sure you get the diff fluid serviced as it's usually under an hour of labour and like $30 CDN worth of fluids, simple drain and fill.

The Rear Differential Oil Recommendation.
I’m trying to figure out what is the best option for the rear differential oil.
The Toyota oil is $40 a liter, I think I can get better oil for less.
The manual states: LT 75W-85 GL-5. I understand the 75W-85 GL-5 part, but what does the “LT” stand for? Does anyone know?
Do I need the “Limited Slip” type or not? For a quick test I lifted the rear end, and when I spun one wheel one way, the other went the opposite direction. The internet says that this suggest no limited slip oil is needed, but it also says that limited slip oil will not hurt non-limited slip differentials, and it’s better to be safe than sorry.
What oil do you use?

Just get Mobil 1 synthetic gear oil. 75W90. You will be fine. I have been running it for over 50,000 miles and 2 changes in my RX350. The difference between an upper viscosity of 85 and 90 is negligible and will not make any difference regarding performance, reliability or mileage. LT may mean Light Truck, but I would not worry about it.
It is available at most auto parts stores and probably Wal-Mart. You do not need any limited slip additive.
Most of the Toyota/Lexus OEM lubricants are made by Exxon/Mobil.

This is for the Highlander, but it is exactly the same on the RX. The transfer case is near the front. Also look on youtube for either RX350, Highlander or Venza.
