need help

When using a pickle fork no rubber can be wedged between fork, ball joint and spindle. It will absorb all the energy from the hammer.

For separating upper ball joint from spindle I use a homemade tool consisting of a bolt and threaded rod coupling nut that exerts force on the upper & lower ball joint stud when expanded. FSM had a diagram showing how to make it.

No beating with a hammer, no destroyed rubber dust cups, and no body damage from misplaced hammer swing. It just popes the thing loose.
