Which Differential Oil - 75W-85 or 75W-90? Even Toyota doesn't seem to know.

Where did you get the parts numbers, TIS doesn't seem to list them anywhere in the instructions.
For the record, Toyota told me that they would get back to me...I'm still waiting. Less than stellar customer service.
 
What I've gleaned from TIS (part # are from various Toyota parts sites):

Engine oil:
ILSAC GF-6A (Toyota 0w20)
Part number - 00279-0WQTE-6S
Capacity –
Drain and refill w/o oil filter (5.6 qts)
Drain and refill w oil filter (5.9 qts)

L580F Hybrid Transmission:
(Toyota Genuine ATF WS)
Part number – 00289-ATFWS
Capacity – (13.2 qts)

Engine coolant:
(Toyota Genuine SLLC)
Part number – 00272-SLLC2
Capacity –
W/O Rear air (12.2 qts)
W Rear air (14.3 qts)

Filled with TOYOTA SLLC at the factory. Only use TOYOTA SLLC or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, non-borate coolant with long-life hybrid organic acid technology (coolant with long-life hybrid organic acid technology consists of a combination of low phosphates and organic acids).

VF4CM Transfer case:
(Toyota Genuine Transfer Gear Oil LF or equivalent SAE 75W)
Part number – 08885-01806
Capacity – (1.5 qts)

Differentials:
(Toyota Genuine Differential Gear Oil LT 75W-85 GL-5)
Part number - 08885-02906
Frt - Capacity – (1.3 qts)
Rear - Capacity – (9.5 qts)

Brake Fluid:
(SAE J1703 or FMVSS No. 116 DOT3)
Part number – 00475-1BF03

I changed the oils recently, and I had the local Toyota parts dept look up the part numbers for the various crush washers and oils.
 
Parts Souq appears to be for the Euro version which is fine for most things, but not everything.

Also the transfer case at least that diagram doesn't show a single gasket.
Yes, they don't have our frame number yet, might take a bit longer before it gets in there but it a valuable reference for most things.

The gaskets are all there you have to look at the correct parts diagram there are multiple diagrams for the xfer case I just linked to the one showing the crush washers, listed as gasket no. 1 in the diagram. There are another two diagrams with all the case gaskets.
 
Front Diff:
  • 10mm Hex for both drain and fill plugs
  • Fill plug = 40nm

  • Drain plug = 50nm
  • Fill & drain plug washers = 12157 - 10010
  • Oil spec LT 75w85 GLS (08885 - 81060) 1 litre bottles
  • Oil capacity = 5.62 litres

Transfer Case:
  • 24mm socket for both drain and fill plugs
  • Fill plug = 37nm
  • Drain plug = 37nm
  • Fill & drain plug washers = 90430 - 18008
  • Oil spec LF 75W (08885 - 81081) 1 litre bottles
  • Oil capacity = 1.40 litres
I just bought the washer and gaskets from my local Toyota parts dealer and I was shocked that it cost over $50 for gaskets alone.
I’m not sure how they justified the prices.

I’m sorry but you got robbed.
I think $17 is a little steep.
Edit; I’m sorry I just realized that you got a quantity of 10 each. IDK the quantity on the bag shows 10 but your receipt shows 2,3,1. Dealers probably have a huge mark up.

Yikes, I purchased my gaskets from my usual very overpriced dealer for $10.00 including the tax.

I returned the washers and went to another Toyota dealer that’s about 15 miles from my home (AutoNation Toyota in leesburg Virginia). They sold the same washers for $16.
When I first bought the washers from Ourisman Toyota, I even asked the parts rep if he was selling me 10 quantities for each kind and he assured me that he wasn’t and the prices was correct.
Some dealers are just criminals.
 
Took me 3.5 hours to change my engine oil, filter, front differential and rear differential oil change. Thanks to each and every one of you to help me find the specifics on washers, torque settings, and the type of oil used in the diffs.
Next project is to change the oil in the transfer case.

How'd the differential fluid look? How many miles on it?
 
For those of you who have done this yourself, what would you say the cost was, including the oil and washers? The Car Care Nut (Ahmed) says you should pay for 30 minutes labor if you take it to a shop (he even has a good video showing how to do it yourself). My mechanic quoted me $150 which I believe is a full hour. I’ve been going to him forever and he’s awesome but I think a full hour seems a little high. But seeing what some of you guys are paying for oil, washers, etc., I’m wondering if I should just have him do it. I don’t have a lift and climbing around under the truck is becoming less fun with every birthday. There’s no way I trust my local dealership. They’re terrible and I’ve caught them cutting corners too many times. But I’ve been changing oil in the LC and it’s super easy. I used to do the gear oils on my 4Runner and it was always easy. But the 4Runner was much easier to climb under than the LC
