Corn Head Grease Questions

    About to put knuckle back together. Questions using Corn Head grease.

    1. I assume you use it for bearings and all inside the front wheel area?

    2. How many tubes does it take for both sides of a front end?


    Thanks.

    I buy two cartridges and really pack the knuckle full before installing spindle. One tube may do it or part of a second tube.I always pack the kingpin bearings before installation with a good high pressure molly grease. mike

    I bought a case of corn head grease to try in the transfer case. but my PTO engagement gear has worn a groove in it's mating gear in the transfer case, creating a lot of shavings. So until I get a clear oil change I'm not willing to give it a try.

    I think cornhead grease in the transfer case would be a monumental folly. It does not flow until it is hot, it will be very tough to drain unless it is really hot, and if you do get it to drain it will need flushed with a solvent to get the accumulated sludge and metal debris out. Not an expert but I don't see the intermediate shaft surviving it.

    This is one side of the discussion.
    Others in favor have said, the shear qualities it see in the device it is designed for, is excellent for a transfer case. :shrug: Many have talked about it but I have not heard any results.

    As for flow, I have been working with this stuff trying to decide if I want to do this, if you put some on your hand it almost melts at body temp, it's more like pudding than grease. My transfer case gets really hot, it has exhaust pipes on both sides, and it gets hot enough you can't touch it, and as for draining,...... The PTO adapter I have, has no drain plug like the cover had, so to drain it I have to remove the PTO adapter and if done hot most should flow out. .And if it does destroy the internals, I have another D20 in the barn.
    Also I am looking for this to be it's last oil change. It looks like my Jeep and trailer will become trailer Queens as my wife would like to join me on my travels, so we'll be driving the Suburban and car hauler cross country.

    So why not try it and settle the question. ...... Or pass it on to my son and let him figure out how to drain and flush:twist:

    Regardless of the discussion, the Borg-Warner three-speeds all share oil with the transfer case. You can't run a different lube in the transmission and the transfer case - they mix. T-98 and T-18 yes, anything else, no (though I still say a thicker lube is folly). Desert Runner having a '78, that's different - the T-150 is not Borg-Warner and also separates the two cases - but not for an early. I'm siding with Arnold Layne, though not for the reasons he states.

    IMG_8616.jpg IMG_8612.jpg I use enough of this stuff each year, and 'tis the season! If it would flow much it would not work in the corn heads for long because it would leak out. I put a slob of it, genuine John Deere and about 3/4's tall, on this tire this afternoon, complete with toothpick. The blue glum is regular gun grease.The hot pic is after one hour, the other is a little more than another hour later. The quality of the lube is fine, I would be more worried about the distribution of it, would rather have oil reach the bearing before the bearing needs oil. Just my thoughts, and I do understand that the chances of me being way off base are always very high.......

    I'm with Tim and Arnold, I can't picture the bearings lasting very long at all. Especially the intermediate shaft rollers. Even down here straight 140 wt. oil is too thick during cold weather and it's oil. I can only imagine what would happen with even light grease.

    So plain 90wt for trans, transfer, Diffs and Corn Head for knuckles? Is that the bottom line?

    That's my preference for sure.

    The thickest we ever ran outside the knuckles was 140 at times. Dad would mix 140 with bearing grease to make the knuckle pudding and put half 140/90 in the tranny and tcase. Those never gave us issues in the 40+ years he did that.

    so that would be in place of the corn head grease in the knuckles?

    Yes. The corn head grease wasn't what willys originally called for, but has been proven to be as good or better of a solution that the original spec oil for the knuckle.
