    I bought some crush washers at the dealership and the parts guy told me I don't need to change the fluid since I've only got 37k miles on it and that I shouldn't put 75W 90 in it because it calls for 75w 85.

    How many have done what I'm about to do and put a lot of miles on it without problems? He said it's $50/quart and I told him that I think it's a gimmick by Toyota to get more of my money since I can seem to find the shit anywhere but the dealership.

    $50 a quart is a complete ripoff. Mobil 1 or Amsoil severe gear 75w 90 is $10-20 a quart, and a lot of people use these fluids in there T case and diffs.

    15K is the recommended mileage for the rear diff. I always change mine at 15K. I used to change the T case and front diff at 15K as well, but since the fluid came out very fresh looking every time I did them, I save the front diff and T case for 25-30K. If your at 37K, you should do all three at once. Its very simple to do them, and it will save you some money to DIY.

    I used Royal P in the rear once, and it was $20 a quart. I swear that it made my rear diff howl just a tad, and after research on Royal P's lubrication properties, I have been using either Mobil 1 or Amsoil.

    Thanks man. The guy told me the service interval for the front diff was 100,000 miles. I have royal purple in the rear diff and haven't noticed any noise so far. I've only put about 30 miles on it, though.

    I used plain old 75-90w Valvoline oil for my rear differential and bought a couple ounces of LSD fluid since my truck is a Sport model. I used Redline full synthetic for the front diff and transfer case.

    Looks like I'm not changing the front diff oil today. One of the bolts on the skid plate is stuck on there pretty well. I tried PB blaster, and when that didn't work I decided yanking on the socket wrench might do it and I stripped the bolt. Fml.

    Breaker bars or something on the wrench works wonders. You will be fine with 75 90. I just changed all three on mine. All looked good except mainly the front oil looked dark. I replaced all 3 of mine with 75w-90 castrol syntrax gear oil.

    Royal Purple has crazy pricing on their gear oil. Their motor oil is slightly higher than most, but their gear oil is outrageous. Didn't used to be. Last time I bought RP 75W90 was about 4 years ago and it was $10.99. I still have one quart left from that purchase. I'd never buy it now that they want $23 a quart, when you can get Amsoil Severe Gear Oil for $11, or Mobil 1 for the same price. A pretty purple bottle with a yellow top doesn't warrant double the price.

    You'll be fine with 75w90 though I think royal purple is a bit of a gimmick myself.

    Be sure to coat the threads on the skid plate bolts with anti-sieze compound before re-installing them. It will keep the bolts from rusting in place and make them easier to remove next time.
