Very nice pics.
I just replaced ball joints on my 190 and used this as reference.
I did the hole thing without a press.
Mine had come apart so it was much simpler.
I supported the lower arm with a block of wood and used a socket to drive out the old ball joint.
Then after having the new balljoint in the frezzer all night. I warmed up the lower arm with a propane thourch and it slid right in. Just a small tap with a socket and hammer and it was home.
