But just in case you guys are wondering..... I also use the hammer method .
Here is the proper tool to use:
Harbor Freight and it's always worked perfectly.
3/4" Forged Ball Point Joint Separator
quoted for truth.
It can be a real pain, so be patient. I swear you'll feel you've spent the day playing thor
The way i look at it, if you need anything more than a hammer than you are doing something wrong, .
Now if your working on an old car like my torino (the upper is pinned in) big PITA. I had to break out the grinder on that !
to answer your question I've seen a mechanic use a air-powered tapered fork of some sort, with impact pulses. I dont know the name of it but the air forces the fork between the ball and the joint and forces them apart. I suppose a clamp of some sort to re-press back together? Also you'll need a tool to re-press the boot back on... I tried this myself and used a extremely large socket, but the diameter wasnt right and it tore the rubber boot, and grease would leak out. FAIL
OR pickle fork and hammer as mentioned above, but it can gouge metal and damage rubber boots.
