2010 Tundra: diffs and transfer case service
Posted: Sun Nov 23, 2025 5:01 pm
These go together because the fluid seems like GL-5 75W-90 in everything.
Rear diff fill and drain plug torque is 36 lb-ft
Front diff fill and drain plug torque is 29 lb-ft
Transfer case fill and drain plug torque is 27 lb-ft
Diffs technically take 75W-85 GL-5 but I'm sure 75W-90 is fine.
Front diff holds 2.2 qts.
Rear diff holds 3.8 qts.
Transfer case takes 75W-90 and holds 1.2 qts.
I would need 8 qts of 75W-90 for all of this. Nice and easy. I will make sure to get the kind with LS additive built in and just use it everywhere.
Also need to buy the crush washer kit from Amazon.
Video to reference but some of his torques are wrong and this is very simple work: https://youtu.be/UgqPKS1TEzU?si=pBPb7O5nxblXiBcj
