    I have used Lubriplate 1200-2 for 45 or 50 years and never had A problem.
    I would repack the steering knuckle every 10,000 miles . Never have greased the knuckle in between
    repacks.

    Bill at Bill's Jeep in Denver Colorado was trained At Willys Overland in Toledo Ohio and this is the
    method He used also . He would cut off the square nut on the plugs on the knuckle so they couldn't
    be lubed between repacks.

    Same as Focker. Just picked up two tubes .Takes about a tube per knuckle if I pack it in during assembly of axle.Nice and full and plenty of lube getting to that upper bearing when axle is engaged.

    By repack you mean new seals on the back of the knuckle?

    As I have read, this type of lube is used vs grease to be able to have lubrication all the time, since as it moves it gets liquified but it doesn't leak because around the seals is thicker (not moving much). Grease would sling onton the walls leaving the joint dry. My question now, after this long tirade: do I need to grease-pack the bearings for the king pin or the lube (specially the top) is enough?

    Just an FYI; in researching Corn head grease, I learned that it is a urea based grease and doesn't play well with other greases. I got a urea based grease for the bearings and then Corn head in the knuckles.

    I don't know if it's the FINAL answer, but it's an answer. Made sense to me to use compatible lubes.

    Or repack them with the wheel bearing grease and fill the knuckle with 00 grease and leave the old knuckle seals on it and go. Thats what I did this week end and packed the carden cross ujoints too

    Mr. Focker, since I am done rebuilding (did the best I could) my front Dana 25, I am ready to move on to the knuckles. Not a big deal there. My question is this: I am trying to decide which type of lubricant to put into the knuckles. So far I favor CHG and I intend to also buy poly-urea grease for the bearings, since it does not play well with regular lubricants. The differential oil is regular 80w. If the axle seals (which are new) leak, wouldn't that be a problem? And if so, how big of a problem? Have you experienced something like it or am I overthinking it?
    Thanks!

    Isn't there a seal that separates the knuckle from the outer spindle? Pretty sure that's the route the lube would have to take to reach the wheel bearings. Pretty sure there has to be something there, since the originally spec'd knuckle oil would be a mess if it went out the end of the spindle and into the wheel bearings. The outer seals will just leak onto the ground or onto the backing plates and wheels, IIRC.

    I was referring to the seals at the diff carrier, since this one is filled with oil.

    I haven't, but you're probably overthinking it. ;)

    The gear oil would lay in the axle tubes if it got passed the seals.those tubes can hold a good amount of oil. As far as I know there is no seal on axle/spindle.The axle goes thru spindle and rides on bronze bushing in spindle .No seal. Nothing to keep oil from migrating from knuckle to wheel bearings .Probably not good to overfill knuckles with gear lube. Knuckle pudding should help slow it down.I don't recall this being a problem on any jeeps I have owned or worked on. mike

    Any lube is better than no lube.
    I mix my own also.

    Does anyone know if there is a gasket to install in between the knuckle and the spindle?
