It's not a job that can be done easily in a driveway.  Those SOB's need
to be pressed into the knuckle, I haven't seen any on a Jeep that could
be 'sucked' into place.

You have to do a preload on that sleeve using a special notched wrench
with the lower ball in place, then set in the top ball's nut.

On the last one I tried, when I tightened the top nut, it just sucked
the ball joint out of the socket.  Didn't matter the order of
tightening.  No amount of jacking, 8' pry bars with 2 big construction
workers hanging on it, a 10 lb sledge or any amount of cussing would get
those damn things to seat.  One gent I know used a 40 ton press to get
his to seat.

I recommend you get the cheap Haynes manual for your Jeep.  It is about
$20.00 and has the procedure outlined with the torque settings.  The
Haynes CJ manual is actually the better one for your engine bay and
wiring, but the YJ one should do for the ball joints.
