I have to replace my kingpin bearings and I have a few questions.
Are the kingpin bearings lubricated from the gear oil in the knuckle, or by grease. I didn't think the axle ujoint would fling that much oil up to the top bearing. And if a vehicle that is used in 2WD all the time, wouldnt the bearing starve for lubrication if the Ujoint isnt flinging oil up there?
When I install them I am going to grease them up good and seat them down. I was wondering about the lubrication of them, because I got a set of axle ujoints that are "maintenance free" permenant lubricated kind, and I was thinking that I could run the axle without filling the knuckle with gear oil, or grease.
I previously used grease in the knuckle. But when I was going to do my disc conversion, i bought new knuckle gaskets and then planned on using gear oil to lube.
But I I can just grease up me kingpin bearings, and go with my maintenance free ujoints, then I dont have to put any fluid in the knuckle, then I would never have the mess of oil leaking through the seals.
Does this sound Kosher, or am I dreaming?
Also Does anyone have the "Kingpin replacment" article from four hweel drive and off road? I lost my copy and I need to know how to shim the caps. Also what is the "pounds" they said the knuckle needs to turn. The measurement they used with that fishing pound scale.
Thanks

I have used only grease in mine. I may just keep it empty. I am using Mobil 1 grease currently. I will grease the king pin bearings. The bottom bearings will be fine, but i was worried about the top bearings having the grease drip out. I dont know how hot the kingpin bearings would get under normal use. I dont think it would get that hot to melt the grease so i think i will be safe. And the ujoints are the Maintenance free type. And I do not believe the brass bushings require lubrication, so all should be well to run them dry. Only other thing is for the knuckle gasket. Do they need a little film of grease to clean the knuckle ball?
