Corn Head Grease Use

Am in the process of exchanging my grease in steering box, 39 Standard Coupe, to John Deere Corn Head grease as this is recommended for this task by many for its special properties.
Just wondering if this is also suitable to use in King Pins, and if not why not?
For us in NZ John Deere Grease is in a special cartridge which is not standard to our regular grease gun cartridges.
So you have to also purchase the John Deere grease gun to be compatible.
Is this also the case in USA. A ploy for more revenue collecting cby the company!!
Thanks,

No, the John Deere grease cartridges will work in any of my old grease guns. I think they are a standard size.
 
It doesn't require the grease gun sold by Deere. It is compatible with the standard 14oz cartridge style grease guns sold here in the US. I'd expect that something similar is available down in NZ.
 
Same as a regular tube here in the states.
It is a flowable grease, thats why it works so well in steering boxes, it doesn't create a cavity around the worm and sector, but it doe not have the propertys to stick to a surface like regular grease does.
 
John Deere corn head gearbox grease is thixotropic type which is for use where fluidity is necessary but an ability to resolidify is also necessary to reduce seepage and hold lubricant on surfaces. The two best uses are for the U-joint cavity and steering gearbox. It is not necessarily a good grease for high pressure applications. A good grade of chassis grease would be better for suspension parts that have higher pressures inflicted upon them.

The J D Corn grease I buy here in USA fits in my standard size grease gun .
Don't know why it is like that in N Z . I use it in the clamshell on my car because it doesn't break down over time & get " liquid like " . Hence , it doesn't leak as much .

JD Cornhead grease is good stuff. I use on my 39 pickup and 40 Merc. If nothing else, can't you use and empty NZ grease tube and full it with corn head grease?
 
The JDCHG I buy fits into the standard cartridge grease guns I own. I use it in my early Ford steering boxes, water punps, and torque tube type universal joint housing. I suppose it would work well in other areas on these old Fords with grease fittings. However, I would not suggest using it in transmisions, rear ends, or wheel bearings.
 
Thanks for all that. Have also used it in the clamshell. And seems like its not really for the king pins so will stick with the normal grease as per tie rods etc, Grease nipples(Zerk).
The John Deere cartridges sold here are a smaller dia than our normal sized grease cartridges as sold and volume is also less.

I asked for it at my local dealer and found that they don't stock it. Said they only had about 1 request a year.
 
I've never used the corn head grease. I used STP in my 32 steering box when I rebuilt it. Does anybody here have experience with using both? How do the 2 compare ? What is the advantage of using the corn head grease that makes it so popular? Lots of questions I know, but I'm sure I'm not the only one wondering

Most people are very familiar with NLGI #2 moly chassis grease for vehicle lube orders in grease guns for general lubrication.

But there are other grades, "self-leveling" grease of which Picker head or Corn head grease is just one, is simply a NLGI #00 grease which you should be able to get just about anywhere or at least annoy the idiot behind the counter and get him to order some.

I used STP first - it leaked - then cornhead no leak. Never looked back.

I had the exact same experience. Every type of gear oil I used in my 35 fordor steering box, including various mixes of oil & STP, including straight STP, leaked out. I was getting ready for a cross-country run in 2013 and did not have time to rebuild the steering box with new seals and gaskets, so I filled the box with JDCHG and that worked great. That's what's still in there 4-1/2 years later.
 
If only that MM Oil was available in NZ? This seems to be a product able to solve several problems as well as being a good additive to the fuel tank.
Have searched and not available in NZ. Ebay purchase and shipping would maybe be a problem being the product it is from a safety side etc.
