upper ball joint replacement

if i'm reading this correctly, you're trying to remove the ball joint from the upper arm and it is just spinning the the bore and won't unscrew past a certain point?

if this is the case, make sure that the spindle is fully free and removed from the ball joint. i'm guessing that it is, but never know... then get a wedge in between the "cap" of the ball joint and the UCA to apply some pressure and slowly turn it out. i've used screwdrivers, body tools and even a wooden stake to accomplish this. you'll likely have to reset several times, taking a little bite each time as you slowly move it out.

i'd verify that you need the UCA's for the swap before going any further. if not, then abandon ship and let that mess be somebody else's problem.
