Digging this thread up since it's not too old...
Trying to the the knuckles off my 91 10b front... knuckles, tie rod, & steering arm going direct to the scrap yard

And of course they won't budge. Searching thru various threads, I'm a little confused here... do I need that little preload spanner socket to
remove the knuckles (I'm not actually removing the ball joints)? Tried whacking the upper ball joint stud, lower ball joint stud, and the sides of the C's where they go thru, thing ain't moving. Biggest hammer I've got a available is just a lil 4 pounder on a short handle. Gonna stop by Harbor Freight tomorrow and pick up a
proper BFH. Am I missing anything here?
