Default Manual steering gear box lube q

An old wrench told me to fill my manual gear box with grease, not gear lube. Thoughts on this?

If you'll look at the Lubrication Chart in the front of the GM Chassis Service Manual, that's what it shows for the steering gear.

Use GM#12377985 Chassis lube. About $6 a tube with discount. Only one tube (or less) needed.

Now if you are starting from scratch after a box rebuild, many folks are using a synthetic chassis lube for longest/best life. Info on this in the archives.

Am I the only one still having leaks - even with grease?

Not much, but a few (red) drips came out my box a few months after a rebuild.
I used synthetic chassis lube when I refilled the box.

I think the heat from the manifold breaks down even the synthetic grease..

Mine is a '61 - not sure if the box is better insulated on a C2...???

Swapped in chassis grease in my original '61 box 6 years ago and no leaks. My car is driven a lot...

I filled the steering box on my 1960 with chassis grease back in 1985 when I rebuilt it. No leaks so far.

I guess I am the only one...

I am running a NOM SB350 (LT-1, solid lifter, high CR). I see 600+ degrees on the manifold with the IR gun. Maybe more heat than stock?
