Ive had good luck using an anvil as a base, seems to work pretty good. But usually requires and extra set of hands to hold the shaft

the worst ones to do are the injection molded OEM ones that must be heated up to melt the nylon crap out of the grooves that retain the cups


First set of nylon injected joints I ever did,, I had no idea you had to melt the nylon out first....
after stalling my 40 ton press,, I was like WTF.....that little bit of plastic can't be that ****in strong.....
It is.....
I've had flaming grease and nylon goop squirt out and scald me several times doing those...


These wouldn't budge at all using the ball joint press...![]()
Had a three foot cheater on the ratchet tightening the BJ press...no go. I cut the cross out and it was pretty easy after that. With the cross out of the way you no longer are trying to get two caps moving at the same time.
................one day while pressing one apart a cup shattered,and the next day I felt something poking me near my navel--a shard of it was sticking out of my belly,it went in a good 1/2" and never felt it till the next day when it felt itchy and I went to scratch it and it felt like a splinter...it was a peice of the cup where the snap ring goes..I just yanked it out with pliers,and was told later by a doctor I really should have gone to the ER and had a x ray to ensure nothing went deeper and to avoid infection...it hurt there for months afterwards!..
