It's time to oversee the fluids in my '93 4x4 p/u.
The M/T and T/C should have API-GL4/GL5 SAE75W90.
Same in the front axle. For the rear diff it gets trickier...
I believe my truck came with an LSD factory rear end. Truck is actually europeean Volkswagen Taro (Toyota Hilux/Pickup assembled in Germany). I elevated the rear end and both wheels spin in the same direction when one is turned -> LSD?
The FSM specifies a special 75W90 LSD hypoid oil for that application. I can't seem to find exactly that anywhere. Castrol has a 75W140 as a recommendation. Do I dare to put that in there?
