From the 06 FSM:
http://www.ncttora.com/fsm/05+/data/...a/03700210.pdf
SAE 80W-90 should do just fine. That's what all the rest of us use in our Toyota diffs, that or 75W-90. Mainly because SAE 90 is nearly impossible to find.
Tundra rear diffs take SAE 75W-140, and SAE 75W-90 in the front diffs though.
DIFFERENTIAL OIL ADJUSTMENT
1. INSPECT DIFFERENTIAL OIL
(a) Stop the vehicle on a level place.
(b) Remove the differential filler plug and gasket.
(c) Check that the oil level is within 5mm (0 to 0.20 in.)
of the bottom of the filler plug opening.
NOTICE:
• Excessively large or small quantities of oil
may cause problems.
• After replacing the oil, drive the vehicle and
check the oil level again.
HINT:
If necessary, fill the rear differential carrier assembly
with hypoid gear oil.
Oil grade:
Hypoid gear oil API GL-5
Recommended viscosity:
Above -18°C (0°F) SAE 90
Below -18°C (0°F) SAE 80W or 80W-90
Capacity:
Differential carrier assembly front:
1.45 to 1.55 litters
(1.54 to 1.64 US qts, 1.28 to 1.36 lmp. qts)
Rear differential carrier assembly:
2WD: 3.26 to 3.36 litters
(3.45 to 3.55 US qts, 2.87 to 2.95 lmp. qts)
Pre, 4WD: 2.75 to 2.85 litters
(2.91 to 3.01 US qts, 2.42 to 2.50 lmp. qts)
(d) Check for oil leakage if the oil level is low.
(e) Install the differential filler plug and a new gasket.
Torque: Front differential carrier assembly
39 N*m (398 kgf*cm, 29 ft.*lbf)
Rear differential carrier assembly
49 N*m (500 kgf*cm, 36 ft.*lbf)

Thanks for the technical data! Gotta love the your location. Not sure where it is but I'll know when I'm near.
I'll post my results using Lucas gear oil soon.
Thanks again.

OK, here are my results.
I used "Lucas Heavy Duty 80W-90 Gear Oil" (3.5 Qrts) without using an additive and noticed a slight chatter when slowly accelerating. After alittle more (online) research I found a thread that says you can use either of the two additives safely:
Equa-Torque® Differential Friction Modifier, 4oz tube
-OR-
Trans-X Posi Trac Limited Slip Gear Oil Additive, 7oz tube.
Both are made by CRC Industries Inc. I used the Trans-X (one tube). Chatter is gone.
Hope the info helps.

If you use something like a Mobile1 75-90 synthetic GL5 or Valvoline 75-90 synthetic GL5 both of those will already have a limited slip friction modifier added in.

Yes, even Toyota (2 separate dealers) said the gear oil must be synthetic (and an additive) but one dealer said that all GL5's are synthetic. If you research hard enough, you will end up as confused as I was. I have read (on this site) that a lot of members use Mobile1 products. I will start looking into it. Thanks for the input.

Diff Lube
What's up with AMSOIL ? Do you need the additive with that stuff ?
Thinking about it for my 2005 Tundra/auto/V8/LS diff.
All the reviews are great for that stuff. Any one know about it?

Not sure about the AMSOIL product outside of other people saying its worth the purchase. I do have another update regarding "Lucas Heavy Duty 80W-90 Gear Oil". Chatter is back. After MORE research I found a Toyota Dealership (Toyota Place 9670 Trask Ave, Garden Grove, CA 92844 Service: 888-830-1999 Parts: 888-269-3311) that sells "SL2462 API/GL-5 Plus New Generation Heavy Duty Limited Slip Gear Oil" and says NO additive needed. I asked if its the same stuff they use and his reply was no, they buy in bulk but what they sell to consumers is comparable and they stand by it. I plan on changing my diff fluid with the new stuff as soon as I can. The chatter is a bit concerning!!!
Good Luck

Sorry for the delay. Just moved. The product is made by "CRC" under the brand "Sta-Lube".
I have seen the product at TOPS auto and either Pep Boys or Auto Zone. From what I understand, Toyota does not make a Gear Lube.
