Upper control arm removal issue

Even though the UCA is rounded, there should be enough of a lip for the gear puller to grab onto. Put two of the arms on the inside of the UCA, closest to the coilover and the remaining arm on the outside above the spindle. Should be able to get good position and pop out the ball joint. Might take a few tries to line it up, but once it's on there it pops out pretty easily.

Edit: This is also why you need the 5 ton puller .. the 3 ton puller doesn't have long enough arms, and won't grab onto the UCA.
