Rear Diff Oil

[bajasequoia]

Hello
I am a little confused, i want to change the oil in the diffs on my 2002 Sequoia 4wd SR5 and according to my manual the rear takes"Hypoid Gear Oil API GL-5 viscosity SAE90". I can't find any and all the other owners on forums and youtube are using 75W-140 for some reason and some others recomend SAE 80W-90. I don't believe i have a rear LSD so i don't know wich one to buy. Any tips???

Thanks

I do know that the hypoid gears in differentials take only GL-5 (never GL-4). From what I've read and heard, the 75w90 full synthetic of any premium brand is good for normal driving. For heavy duty hauling, 75w140 is better. As far as LSD is concerned, if you can't find it in your owner's manual, you can call a dealer's service department with your VIN and ask them.
