i don't condone doing it this way, but if you must...
keep the tension on the t-bar, pull the drums and junk so you have room to operate, remove the shock, crack the ball joint nut and leave it with a few threads on the stud so that when it cracks the nut will catch the spindle and the whole assembly doesn't fly off and hit you in the dick.
here's the problem with that modus operandi... you only get one of the ball joints under tension to assist in separation, so like, choose wisely. and have a separator tool handy.
pro tip: keep the lower arm on the car to deal with that ball joint, otherwise you need a heavy table with a good vice or you'll be chasing the arm and floppy joint all over the garage floor fussin' fightin' and cussin'
