Rear differential oil 2004 two wheel drive

Factory specs on rear gear differential oil for a two wheel drive Tundra crew cab V8; 2004 model unlimited.

 

Lsd?

 

I am assuming LSD isn't Timothy Leary you are referring to but limited slip differential. Just bought the truck so not sure. Can I get that off the Vin number through Toyota? I thought it took

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

75w 90 synthetic gear oil just not sure.

 

Maybe the website, maybe theres a sticker on the axle. Neither is a guarantee. But if you floorboard it from a stop and one wheel spins, its open. If both wheels spin, its lsd. You'll need about 4 qts of 75w90, and if its lsd it'll take less, and theres an additive you add in (or but lsd oul with the additive pre-mixed).

Drive around to warm the axle up before draining, and fill until it starts to come back out of the fill hole.

 

If open diff, book calls for 75W-140 gear oil. Limited slip is

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

75W-90.

 

LSD usually would have a sticker indicating it's LSD on the back of the pumpkin. See here: https://www.tundras.com/threads/hel...lip-differential-06-tundra.29557/#post-729734

But you should sign up for the Toyota Owners site linked there. And plug in your VIN, assign it to yourself. You can see there what options it came from the factory/port with, including LSD.

Also, if you haven't read it yet, check this thread: https://www.tundras.com/threads/so-you-wanna-buy-just-bought-a-1st-gen-tundra-eh.115928/

Check that timing belt!

 

Still worthwhile to manually check for limited slip. It was not uncommon (and not terribly expensive) to add the Kazuma TRD lsd unit to an open diff.

 

Can you see lsd vs spidergears from the fill hole? Havent opened mine since like 2012.

 

I'm gonna have to ask for a source on this one. I'm pretty sure they are all 75w90 but feel free to prove me wrong.

Interesting.

 

Is there a general rule here? LSD for 4WD.

 

no general rule, plenty of 4x4’s sold with open diff

 

My 06 2WD has a LSD

 

That isn’t always a guarantee, an open diff can spin both if traction is equal. That being said, Open diffs suck!
