Steering box lube?

[TucsonJim]

Can anyone tell me how much, and what type, lubricant is used in the steering box of a 1967 1/2 1600 roadster?
As always, thanks.

I found it in a book. 250 ml of 80W90 gear oil. Fill it to the top.
Thanks

Lots of suggestions regarding "liquid grease" or corn grease or something to that effect here. It is much less prone to leak out over time as the Gear oil seems to do.

Can other grease, like Mobil 1 etc work, or does it have to be “ corn grease”?

0 weight grease, also called corn head grease comes from agriculture applications where gears turn slowly, such as a corn head on a combine. When it warms up it liquifies so it will flow into open bearings and gears. It often gets used for gearboxes that have leaking seals on vertical shafts because once the machine is shut off and the grease cools it won't continue to drip like 80-90 gear oil would. I would stick to the 80-90 unless I had a leak because the steering gearbox will rarely get warm enough for the O weight to flow.

I have used John Deere Corn Head Grease in the lower unit of antique outboard motors that do not have a shaft seal, but only a bushing. In this case, water does migrate into the gearbox. It is particularly useful in this application because it does not emulsify in water and is recommended by most antique outboard groups. I am not sure if this is very useful in this discussion, but an interesting tidbit of info.
