2024 Tundra SR5 4x4 (35k Miles) Fluid Questions

Just purchased a 24 SR5 4x4 and I have put 1k miles on the truck (now at 35,080).

I am wanting to change the transfer case, front/rear diff fluids and grease the driveshaft joints.

I found the fluid amounts/types, but I was wondering what brands I should use besides obviously Toyota. Also, does anyone know the washer sizes and the pounds of torque to use for the bolts?

Transfer: 2.17 qt. (ATF WS)
Front Diff: 1.49qt (75w-85-GL-5)
Rear Diff: 5.7qt (75w-85-GL-5)

for the transfer case fluid should I use Valvoline Maxx Life Full Synthetic ATF and for the diffs should I use Red Line Synthetic Gear Oil GL-5 75W-85?

 

Would Red Line Transmission Fluid D6 be good for the transfer case and Red Line Synthetic Gear Oil GL-5 75W-85 for the diffs?

 

If not OEM Toyota, I like Amsoil stuff.

 

Thanks!
I am correct right, that the 3rd gen’s use 75w85 for the diffs and ATF WS for transfer case? That’s what I understand from online. But on older tundras people say NO to ATF WS for transfer case https://www.tundras.com/threads/transfer-case-oil-atf-ws.82338/

 

I am researching this as well. 75w-85 isn’t a widely carried oil. What is the forum’s opinion on using

$39 75w-90 GL-5 Limited Slip, Ultra Long Drain 500k Miles, Manual Transmission, Gear/Differential Lubricant (1 Gallon)

75w-90 which is everywhere?

 

I just used the

$39 75w-90 GL-5 Limited Slip, Ultra Long Drain 500k Miles, Manual Transmission, Gear/Differential Lubricant (1 Gallon)

75w-90. I can’t fathom what the difference would be. I recommend a transfer pump and potentially removing the spare when doing the rear.
