Subject:What Determines Steering Knuckle Replacement?

Hi all.

Still working on my '88. PO set driver side front bearings too tight;
couldn't move washer even if levering blade at rotor collar.

Here's what I see (can take picture):

- mild heat marks on inner and outer bearing rollers and what are
likely "spin" marks on bearing inner race.

- spindle outer seat: minor scoring. I can *just* feel some ridges
with my thumb nail. They appear/feel very minor.

- spindle inner seat: has marks but I can't feel anything.

P. 40.12   "check for scoring or ridges...... - replace seal ring or
steering knuckle if necessary"  This seems vague as I don't have
enough experience with these parts.

Does "if necessary" mean excessive ridges, play between bearing race
and spindle?

My spare '85 knuckle seats look better (shinier, more uniform
appearance). This is my only point of reference.

New outer bearing fits and I don't feel any play. Measuring both, I
see 19.98 mm  (which doesn't make sense as technically, the bearing
wouldn't fit. I blame my calipers.    < grin > )  Old bearings and
seats are the same measurement as well.

If I keep these knuckles, and install all parts correctly, is there a
pretty good chance the inner race of each bearing will stay put and
not spin? Is there anything else the slight spindle damage could
cause?

Much thanks,

Neil.
