I'll promise you one thing, a steering box does not have near the stress that a CV Joint has. If it will work in a CV joint, it will work easily in a Steering box.

Basic street smarts would agree that the stress-levels are nowhere near the same.
BUT, I am sure there are other aspects of engineering that us Common Street guys don't have a clue about.
If GM, AND richard1 say we need to use something of a higher grade, then I will trust their word over that of a Shade-Tree Mechanic.

Since I am a GM University Graduate, ASE Master Technician for 40 years and member of the GM only the best club, and was Service Director for a GM Dealership for 6 years and owned and operated a very successful independent Automotive repair business for over 40 years, I consider myself a step above shade tree Mechanic. I also he been using CV Joint grease in Corvair steering boxes as well as many other makes since the CV Joint became popular.

Well, why didn't you say so from the start? ? ? ?

Well, Richard did say it, but I have never seen any specs on GM steering box lube. When was the last time GM even offered steering box lube for sale? I've never seen it in 40 years. I am aware Studebaker International offers lube due to customers who did not know what to use in their boxes. Studebaker stopped selling cars back in 1966, so it understandable their lube was long off the shelves.

Craig replies: I think GM Steering Gear Lubricant went away about 15 years ago. At that time I did a Google & Ebay search and found some for sale at a GM dealer. I contacted that dealer and bought a few tubes for my various projects.

Last time I saw some? About 5-minutes ago! LOL

If someone wanted to search for some, the GM part number is 1052182, Group #8.800

You all make far too much about which oil to use, especially in a steering box. Nearly anything is better than what's been inside of those boxes for the last 50 years.

what I used

I have used this on a single box, no issues.

Seems to be the right viscosity.
