Oils and Fluids

I recently purchased a 404 and was wondering if there is a lube chart online, and what the recommended fluids/ oils are. (ie. zerk fitting locations, oil weight for engine and trans, suggested diff fluid etc.) Any help would be appreciated!

Make sure you buy the right 80-90, series 4 not 5 I think.

The most common one eats yellow metal apparently (and the mogs got lots of yellow metal in it).

What do you mean by series 4? Is that like the GL-4 or GL-5. I bought some Valvoline 80-90 gear oil for diffs and trans and portals... no mention of 4 or 5 series. How would I find it?

Yellow metals would be things containing significant quantities of brass (like syncros and bushings). Not really an issue in the axles or portals but a definite concern in the transmission.

And yes, the 4 is GL4. GL5 is not safe for our transmissions.

Yeah, just make sure the transmission fluid is GL4 or "Yellow Metal Safe". Axles/Portals you can run anything.

Great info, thanks. From the research so far...
Gear oil: 80-90W
Tranny: 80-90W (GL4 safe only!)
Engine: HD 30W
Coolant: Aluminum safe (ie orange, not green)
Brake fluid: DOT 3

Any ideas on safe power steering fluid?
I have a pump/ steering box off of a 406/416. Is it okay to run the lucas power steering "stop leak"? I dont have any leaks, but im sold on lucas products.
