Thread 'The great ball joint debate' https://www.jeepkj.com/threads/the-great-ball-joint-debate.77356/ it's just hole for the cotter pin, you'll end up needing to use the nylock nut rather than the castle but if the earlier ball joint is used on the later models. I don't know how well they work the other way around. This is the k3199 on my 2005. Hole is not quite low enough for the cotter pin, but enough thread for the nylock nut, both come with the moog ball joint.K3199 is for the earliest kj up to 2004.
K80767 is for the rest.
K3199 is a little bit smaller
If your truck is 2002-2004 and you are experience it with k3199, maybe the lower control arm has been replaced with a +2005
I think you're meaning knuckle rather than spindle, not that it matters a whole lot. But the ball joint case as you call it and where it fits into the spindle I'm pretty certain are the same for all kj's. But they could certainly wear out and get sloppy over time and use.I am talking about the spindle itself, not where the shaft of the joint goes through the lower arm but where the ball joint case itself presses into the spindle
