I didn't have to remove the control arm bolts in the first place. Disconnect the shocks and sway bar. Push down on the control arm with your foot and the spring will just pop out. It was a bit of a pain to reconnect the sway bar afterwards. Both control arms must be raised up to align the bar into the brackets....easily. I was messing with shocks, springs and ride height constantly and got good at it.
I may be forgetting something. Age.......
