[1968_K20_4x4]

Recently I went through the closed knuckle Dana 44 on my 68 K20, checked everything and replaced the seals. Everything was in good shape so I cleaned it all and reassembled it. I assumed that the wheel hub bearings would be lubricated by the oil in the knuckle ball... but now I am not so sure. So my question is, does oil flow through to the wheel hub bearings to lubricate rhem from the knuckle ball in a closed knuckle axle? Or should I have lubricated the bearings when I reassembled the axle (they're currently dry and I have not added any oil to the axle yet) I have the axle all put back together now and dont want to have to tear it all apart if I dont need too, but I also dont want to ruin my bearings without oil. I appreciate any help from someone with the understanding of how a closed knuckle is designed to work. Thanks
