Doesn't hurt to ask now does it? A beam could be considered an arm and it is below the coil spring....is it not? And it does have a bushing at the pivot. I did want to assume it was an SLA setup, and wanted to ask first in order to be on the same page.
From my experience, a ball joint press kit works quite well. You may need a regular shop press......but the ball joint and a 1/2" impact have worked most the time for me.
Also be sure to mark the depth of the bushing, and try to match it the best you can.
