Vehicle is a 75 series Landcruiser, and i am about to do the diffs and gearbox/transfer case. Im a little weary on what oil to use
Gregory manual says to use;
Gearbox and Transfer Case- SAE 90 GL4 or GL5
Front Diff- SAE 90 Hypoid Gear Oil GL5
Rear Diff- SAE 90 Lim Slip Hypoid Gear Oil GL5
Penrite Website says;
Gearbox/Transfer Case- Transaxle 75
Diffs- Hypoid 80W/90
Now i already have some Lim Slip oil for rear diff so thats ok, its just my local Auto One only has Hypoid 80W/90, no Transaxle 75. What i want to know is can i use the Hypoid 80W/90 for my Gearbox and Transfer Case or should i try get some Transaxle 75 somehow. Is there much of a difference in the two oils? Its just that the bloke at Auto Pro told me it would be fine so i brought 7.5L (2.5L Bottles -No Larger amounts available, Rip Off), but now it makes me wonder if Penrite say to use the other stuff.
Any mechanics out there or 75 Series owners
