Oil for axle and gearbox

[gotoy]

Appreciate good advise on correct grade oils to use:

1. 8" axles. ARB lockers installed.
2. H55F gearbox
3. 15B-T engine.

Cheers!

Here's what I used in mine with in order from left to right: axle, transmission, engine.

My rear axle is a 9.5 with a LSD but in my forty with an ARB I used the same grade oil and made sure to use synthetic. I also have a 1HZ but I'm sure engine oil is the same for both.

My manual calls for:

Trans - API GL-4,5 SAE 90
Xfer - same as above
Diff - hypoid gear oil API-5
SAE 90 if above 18 C
SAE 80W or 80W-90 if below 18 C
