    Yes, the oil flows where it should. :) An oil and grease mix is better than straight grease, and straight oil is the best.

    Well, you don't want EP grease in there. The additives are good at protecting from shock loads but increase wear from scuffing dramatically in worm-gear applications.
    Thick oil, the thicker the better if your seals are shot... and they likely are if someone thought grease was a good idea.
    I'd suggest ISO 640 or 1000, available from any of the usual sources (MSC, McMaster-Carr, etc.).

    I just checked mine, since I'm about to install it.
    It was filled with red grease.
    Now how the hell do I get that out of there?

    I thank you and look for a Jonh Deere dealer, by the way I know one because my landmower is a J.Deere.
    But I wonder if heavy oil is not the solution, sae 80 : I have filled this steering box yesterday with some oil, same as for transfer case, there is no leak and turning the steering wheel is nicer than before.
    If I want to put grase, I can but as explaned by a member grease works well when there is a contact, a pressure, but not when parts are free in a box.
    In this case grease can stay on the walls and not enter in the mechanism. At the contrary oil goes everywhere.
    I suppose that a mix of both, or special expensive products can be good. ANd of course grease will be effective, but maybe less than oil in this situation.
    Today I am extremely satisfied by adding the sae 80, and if no leak coming in the future I believe that it is the solution.

    There are many parts to oil and grease on a Jeep! This steering box is not really on the list but I see the difference.

    In fact, since I have got my Jeep, 5 years, I spent some money (my wife asks always to give her the same amount as what I invest in the Jeep) and every year my Jeep is BETTER! (y) Until tomorrow, of course;) but I enjoy it a lot, less noise, smoother, engine runs well, starts immediately, good brakes ...

    We have very nice dry weather in my part of France, no rain in one month, big sunshine. In the day I use the 'bikini' because of the sun, and end of the day no top, when my sons ask for a trip, and windshield down between the fields and in some fields when it is possible.

    We see wild animals (no bears or crocodiles..:rolleyes:) deers, rabbits, prey birds ...it is a (modest) paradise.

    Less noise, smoother, etc... is this still about a comparison to what you give your wife? :)

    What kind of red grease is it? If it's safe for yellow metal and non-scuffing you can just add oil to make sure you get lubrication everywhere.
    Really, that John Deere corn-head grease is a semi-fluid of about ISO-1200 and nothing like axle grease.

    I don't know what kinds of grease it is.
    All I know is that the box was rebuilt by someone in California.

    My oil rep. At work is supposed to drop me off a case of the corn head, or as he calls it corn hole =), grease next time he comes through.
    Pretty neat stuff. I used it in my knuckles and it came out of the grease gun like oil but then just changes back to grease.

    They might have know what to use and put that in as a bit of 'break-in' lubrication, call them up?
    Solvent will wash out the suspect grease, or you can use oil. It works even better if you heat the oil before pouring it in.

    I'd still rather use heavy oil since the wear particles don't get trapped in the gearing.

    If you want to know too much about the challenges and choices, you can look here:

    This is highly specialised and interesting. Thanks.

    Glad I could help. We have a wide variety of gearboxes spanning over 125 years at my work so I've spent a lot of time learning about lubricant classification as a result.

    Interesting info.
    I have no idea who rebuilt the box so there's no one to ask.
    I'm thinking I might just pull the cover and get out what I can then refill with the corn head grease.

    Walcks did a video on the rebuild and called for 140 weight. I haven't goten that far in my build yet but it makes sense.
