Upper control arm bushings

[tdangle]

I need to change out the upper control bushings. Did this a while back on the other side, removing the entire upper control arm, I removed the upper ball joint wrecking it in the process.

I am looking at it now and think I may be able to replace the cross shaft and bushings with out removing the ball joint from the spindle. Has anyone ever done this? If not, I'm open to suggestions.
