Front and Rear Diff fluid change

[Jacabbysal]

I think I will stick with Amsoil.

Ran it in far more severe conditions in race trucks then my 4runner would ever get close to.

If $25.00 for a gallon of Mobil 1 0-20 is too expensive for you, I don't really know what to say. Walmart, best price. Absolutely no reason to ever run junk oil. You spent what, 35K - 40K on your truck? Don't treat it like a POS.

I am pretty sure he is talking about the transfer case fluid. The hard to find, $60 a quart, dealers don't even use it, fluid.

So $60 is not worth knowing the PROPER fluid is in your case? Dealers not using it is the worst possible excuse out there. We all know dealers are hacks, some great mechanics but not many. For me, the $60 is more than worth the peace of mind. Put 75-90 in your case and see if Toyota covers it if it blows up. Is voiding your warranty really worth it for $60?

Wow, being off here for few days and noticed things escalated fast. I don't think 75w-90 fluid would damage anything but when i had 75w-90 Royal Purple in my transfer case it didn't shift in/out of 4wd smoothly and also seemed to run roughly in 4wd. When I reverted back to 75W OEM stuff all issues went away. If anyone makes 75W oil down the road I'll buy it but until then options are limited to OEM and few oil brands (all of which are formulated for manual transmission).

Getting ready to do my wives limited but I am having trouble finding a reliable oil change catch basin I can use to transport to a facility.

Any suggestions would be greatly appreciated.

I changed my t-case fluid this summer and used this.

Working fine. I've heard the Toyota stuff is very hard to find, most dealers don't carry it, some wont ship it and most service departments fill your t-case with whatever gear oil they have in big drums in the shop.

I just can't understand why so many people are dead set on not using the 75W oil? Why is that? It's proven the additives in the OEM 75W far surpass anything else available anywhere. You would think that's enough to convince even someone with zero automotive knowledge that it's a superior oil and designed like that for a reason.

Ignorance resulting in fear of your unknown, explains why people like yourself hugely overpay for an OEM branded commodity product. Even Borg Warner’s engineers said that only the 75 number matters.

We’ve got 150K miles on a SR5 purchased September 2014. Over 100k of those miles are on Mobil 1 or Valvoline synthetic 75w90 with no problems and little if any filings on the magnetic plug. We intend to drive the truck to 250K or 300K. And yes we paid $35K cash and I have no fear of a transfer case failure. Rebuilt ones are around $1K.

Changing the oil frequently with 75w-90 is far better than not changing it at all like probably 90% of the 5th gen 4runners on the road that are running fine.

I did Mobil 1 75w90 in diffs and t-case on both my 4th gen and 5th gen and they have shifted into 4wd like butter and run great, coming out clean with basically nothing on the magnetic plugs each time.

To each their own, I am not scouring the internet to even find the stuff that takes 1.1 quarts so you have to purchase $120 of oil.

I have no problem paying $60 for the correct fluid. For those under warranty, use the correct fluid. If you do happen to have a failure and the dealer determines you used the wrong fluid, good luck getting it covered.

Man if you're counting on a Toyota t-case failure you should definitely be buying Mega Millions tickets. I'm not sure which is longer odds. Probably the transfer case failure.

Unless it's not properly lubricated. 4.0 last 350K plus if taken care of. Really that goes for anything. Take care of it properly and it'll last. You guys can do whatever you want, your truck, your money, your choice. I choose to use the correct fluids.

Transfer case oil isn't that magical. It doesn't get particularly hot, nor are they particularly heavily loaded gears. Because there are brass sychros in it, it just needs to not corrode the yellow metals. Theoretically, you could get away with motor oil. There are transmissions that use motor oil. I'm going to bet on mega millions.

If there's brass in these cases, even more reason not to use the synthetic 75/90 as most of it has LS additive in it. They will not play nicely together.

Proudly accepted :banana:

OK. This can get filed under the "technically" category... I did some more digging with this T-case fluid type debacle.

So, the manual states "Toyota Genuine Transfer Gear Oil LF or equivalent ... SAE 75W"

Redline 75w-85 Gear Oil states that it "Satisfies the gear oil viscosity requirements of SAE ... 75W..."

Based on the way it's written, Redline 75w-85 would be considered an "equivalent". No mention of GL rating in the Manual. WARRANTY PRESERVED

.... Carry on

Getting ready to do my wives limited but I am having trouble finding a reliable oil change catch basin I can use to transport to a facility.

Any suggestions would be greatly appreciated.

I use a big open topped one with a spout on the front. When done, I use the handy attached spout to pour it into old 1 gallon motor oil containers that I always keep around just for oil storage/transport. I usually have 8-10 of those filled up on a shelf in the garage before I make the dump trip. Mine looks like this.

That's a great idea. I don't have oil gallon containers but have been saving milk jugs to do that. I just had nothing to drain it in. Thanks.

Just ordered similar product. Thanks again. Getting all this together costs, including oil, but I know it much cheaper than dealer.

Watch out for milk jugs, they will break down in time when they are filled with oil. Fine for short term use.
