QUESTION FOR UCA BALL JOINT SEPARATION
I agree it's hard to imagine and it seems like the bushings not being fully seated would be far more likely. I've checked the mounts, they are not bent. One thing I did do before buying another arm and popping the upper joint is run a 3/8's bolt trough the A arm (1/2" was too big). What I saw was if I ran that bolt down the bushings fit in the mounts with the proper spacing on both inner and outer washers on the bushings. This again tells me the arm is spread. I've done some rough side by sides with my "new" arm, it seems narrower in most positions.....but not all. I'm about to finish pulling the old arm off, put together my bearing press and tear both arms down.
