Welcome to site. Wondering how your J is coming along. I like the closed knuckle axles, changing the seal is a good idea as it holds in 80/90. When you pulled it apart how much ran out? If none, it hasn't been takin care of properly, no and I mean no grease goes in that axle bearing/knuckle assembly. I drive 3 J trucks with the closed knuckles, 1 going on 35 years, 1 for 12 years and the 70 for the last 8 or so. Between the 3 probably 150,000 miles, not a spec of grease has ever touched the wheel bearings. When I assembled them the bearings where dipped in 80/90 and installed, also DO NOT put any grease in any part of lockouts. The 80/90 you put in the ball lubes everything, now I've read the post and such on mixtures/pudding folks use. I've never had an issue, period, and my lockouts work like they should always. The 70 when I built it I went through front axle also and put 35,000 miles on it the first year, about that many more sense and other than pulling one of the bottom 4 kingpin bolts to drain and change the ball oil every couple years it's been perfect. Yeah I get a drop or two of oil on tires seeping out of ball seal if it sets for a week or so, that don't bother me knowing that all is being lubricated properly.
