Found on another forum , users were discussing which oil for what -
"Let's clear up the confusion;
The Prado is an all wheel drive (AWD) hence it has a center differential. The center differential is intergrated into the transfer case (making it an AWD transfer case)
1 case, 1 oil, 1 drain plug and 1 fill plug.
It takes 1.4 lts of Hypoid gear oil, API GL-5 SAE 75w-90.
So, from front to back you have:
Front diff
Engine
Gearbox
Transfer case
Rear diff"
To clarify the above list further, it would be more logical to start the list with the engine thus:
1. Engine;
2. Gearbox;
3. Transfer box & Center open diff;
3a. Rear open diff (60%);
3b. Front open diff (40%).
The center, front and rear diffs then all have the added option of being progressively locked (in that order) to avoid wheels spinning in soft no-grip conditions.
IMO it's misleading to talk about power, the engine produces power, nothing else does. It's motion that's being distributed to the four wheels, as described above.
Of course, setting off quickly will unweight the front wheels more than the back, and then they're likely to spin until the weight distribution evens out. But anyone who's driven a Ferrari will know they are difficult to drive because they have so much power. Without caution, they would be out of control very easily.
I would think the fun would be in learning how to pull away quickly without spinning the wheels, using judgement and driving skills.
Otherwise we should respect our trucks for what they are and drive them within their limits, as the alternative is likely to be premature failures.
