bottom joint can be done by the suspension alone
undo the nut 1/2 a turn
take off the brake
Hit the eye in the end of the lower arm with hammer
jack under to take the suspension strain
undo
lower down
mind I find that works with the top one as well
it really is best to break that taper first but leave it hanging.
if you can get the track rods off at the outer ends and the pitman arm off you can take the whole cross link off the car
rest each eye on the rear saddle part of your vice or on a curb stone and smack with a hammer
lower shock bolts are also a pain. they press fit into the lower shock eye sleeve
undo nut so it covers end of thread
welly it as hard as you can
this peens over the end of the nut somewhat, which in turn restores its self locking capability
the only balljoint splitter that works is the scissor type with the bolt.
use the bolt only to tension
then
Hit the eye with a hammer.....
I,.e you don't need it if the suspension provide the necessary tension
