How is coil spring compressed when replacing upper control arm?
When replacing an upper control arm, it is important to understand that the coil spring is compressed to half its unsprung height. It is normally compressed between the upper and lower control arms, which are connected on one end to the frame, and the other end to the spindle, via the ball joints.
