Is this spindle/steering knuckle junk??
The (albeit small) gap between the upper ball joint shank & edge of tapered hole at the top of the knuckle. Doesn't this have to be a tight fit over the entire taper?Why would it be junk? Am I missing something?
The knuckle is generally not a wear part unless it gets damaged.
Marker contact looks good. It doesn't rock at all. Edge of shaft where it starts to taper sits about 3/32" below top surface of knuckle. There's about 3/32" of thread length to spare under the nut with it snug. Nut goes from finger tight to 55 lb-ft over about 1/3 of a turn.Do you have any Dykem ?
Lots of felt pen works in a pinch.
Coat male and female tapers to get a read on where and how it is contact if you push together and rub a bit.
You say it does not rock at all ?
Cotter pin hole height OK ? ( somewhat difficult to judge if the joint is afternarket as some sit high and require a washer,,,,,,,sometimes🙄)
Any evidence the hole is not round at edge?
Does it make contact with partial torque ?
