That's what the guy who rebuilt my steering box put in the box. Three years later, it's still steering great without wear or play that I can notice. That's NOT what the factory called for. The '62 shop manual calls for gear oil that 'remains liquid at low temperatures", and I figure that to be gear oil like for a manual transmission, 90W. Problem is that, with sector shaft bushing wear, the play in the sector shaft and an old grease seal at the bottom of the sector shaft in the housing that's dry or cracked, and all the gear oil leaks out of it. Dry again. The extreme pressure grease is what my steering gear rebuild guy uses, and is still in my box.

I have used John Deere Corn Head Grease AN102562 on many steering boxes. Light bodied grease with extreme pressure additives. -30F to 330F rated. will not drip from gearbox.

Like that idea a lot. I think the reason a lot of the boxes went bad was they couldn't keep the lube in them. That would solve the problem.

my manual steering box was leaking from the bottom seal. i removed the top bolt an checked level with a thin handle paint brush, it was low in side. i was advised to add marine grade grease. to get the grease inside i removed the grease fitting tip on my john deere grease gun an the threaded end fit into the bolt hole perfect. not screwed in just slipped into the hole. i would pump 10 shots of grease an drive the car. i kept repeating till i was about a 1/2'' below the bolt hole. there should be the words lube here with an arrow pointing to the bottom of the 3 bolts on that top plate. so after 2 plus years all is tight an steering well. so if i was wrong i sure don't know how i'd get the marine grease out of that box.

I first read this it made me smile. Thinking this must be kept next to the blinker oil. Turns out there actually is such a thing. Who knew, besides you of course.

i had to google corn head grease.
corn head grease is a poly urea based NLGI 0EP grease. commonly used in corn headers and similar boxes. It is a semi-pourable grease suitable for some gear boxes as it will slump to prevent cavitation voids like a #2 grease might cause. Some mowers spec a 0 or 00 grease.. but most spec oil.Jul 19, 2014

Yep, same type of stuff is used in the transaxle of your cheaper big box store riding lawn mowers. Transaxle is made up of two die cast case halves, upper and lower, and no sealing gasket is used between these two pieces...and the mating lip is left as cast. The whole lower cavity is filled with what they refer to as "Semi-Fluid" grease. The consistency at 70° room is about like Jello chocolate pudding..

I thought about this all night. It's just a gear box, correct? Why can't you use just regular grease versus marine grade grease, corn head grease, or the WD40 high pressure grease. It's not a high pressure system.

WD40 Grease is a quality #2 chassis grease. This grease is thrown off any rotating parts. J.D. grease is semi fluid and sticks to rotating parts. You Tube has video.

I'm glad I ran across this as I am wanting to clean up my steering sector soon and the Corn Head grease looks like it will do
the job as a lubricate. Question.....does all the old existing factory grease need to be cleaned out before filling with the Corn Head?

So funny I came across this. I just disassembled cleaned and reassembled my steering box for my 67 Nova. I used Valvoline extreme pressure red grease. I'm pretty sure you're supposed to use grease and not gear oil like some people might tell you. I've never heard of the corn head grease That's pretty interesting. I had an old power cyst unit in the car but I just rebuilt the whole front end and I'm just going with the straight manual gearbox. If I like it enough I'll see if I can obtain some Corvette internals and get a better ratio out of it. Good luck.

Here's a link to a video I took of putting everything back together for the most part. The camera angle kind of sucks and I like to talk so may take a little patience getting through it. Shameless plug....

Do you by chance know how similar the 1st gen steering sectors are to the 2nd gens? I watched your video. I thought
it was very good. Would have liked to have seen you disassemble the parts from the box though.

I think most of these boxes back then were very similar and, in some cases, had identical internals. 67 was the only year that had an independent shaft, whereas previous years were connected to a shaft that went all the way up the column.

Taking the box apart is very simple. I do have a video of that but it's not a bird's eye or walkthrough. Just a video of me taking it apart. Ill throw it up o YouTube and post a link anyhow. The most difficult part is reassembling the ball bearings in the worm gear. But if you take your time it's not all that bad.

The adjustment is something I'm still not 100% sure of but I think I have a general enough idea that will work just fine. I touch on this a little in part 2.

I am very interested in the next video. I have a '65 that has the long shaft that I would like to rebuild. Do you happen to have a
source you could tell us about on where to get the gasket and seals?

it does look like it be easier to do a 67 box than it would be to do a 62-66 box. i'm thinking it would turn into a monster to pull the box an steering shaft from the installed column.

Not sure if it's going to be all that helpful but here it is -

Here are some other sources that may help:

A bunch a sources online have gaskets and rebuild kits. Watch out for some that include plastic bearing cages. They may be fine but I'd prefer steel

The first link below is a place that sells all parts separately. But, like I said, kits can be found all over online. I included a couple of others. I have not purchased from any of these sites as I am keeping my original internals for now.

Here is a company that can convert your box to 12.7:1 (which is crazy). Not sure if they are still in biz but figured I'd drop it in here anyway.
