i do my front and rear diff every 15k miles, yes its over kill i know that but ive always been very anal and meticulous with all my vehicles. i also do my engine oil changes at 5k miles no matter what anyone says and besides its cheap to change
Red Line makes OEM compatible fluids that list the specific Toyota part numbers. Look under the OEM Compatibility tab of each and you will see what I mean. I bought some for my FJ Cruiser but ended up trading it in for my T4R so I will use it in it instead.
Bingo - I used the redline variant for the diffs. I do plan on using the OEM toyota transfer case oil when the time comes for that drain & fill however.

Same for me with transfer case oil. Another good choice for front and rear differentials is Amsoil Severe Gear 75w-90. And the squeeze tubes are real convenient. AMSOIL SEVERE GEAR(R) 75W-90
I got 6 quarts of the OEM diff gear oil GL-5 75W-85
(Oem# 08885-02506) for $178 shipped to CA from BAM Wholesale Parts
My local TOYOTA dealer wanted $110 per quart.
Planning to do engine oil, Transmission fluid drain and filter replace along with the front and rear diff and transfer case the same day. Just gotta find the time to get under the truck and do it all.

Im a huge Redline fan for their oil for motors. That said even using their compatibility guide I had issues in a honda transmission using their product. Anecdotal maybe.. I still use their motor oil.
Just did mine today.Truck has 60k miles on it and fluid was really clean coming out.Went with Royal Purple Synchromax for transfer case and the RP 75w90 for diffs.
Every 60-100K or 6-10years is advisable. 75W-85 Red Line Synthetic for OEM recommended weight. I tried 75W-90 Amsoil and wasn't happy with the way it ran.

I'd stick with Toyota WS for our transmissions. I even use Toyota oil for oil changes but mainly because I get it for cheap.
Toyota dealership sold me 75W90 Mobil 1 for front/rear diff and transfer case. did them at 132,000 KM's (81k miles) and now i'm around 165,000 KM's (102k miles) and have been extremely happy with it No whining, banging noises etc.
