The ST-12 states that replacement of the lower control arm shaft bushings (inner) may be accomplished without removal of the lower control arm and without replacing the shaft. Just unscrew one end at a time and replace.
What about the lower outer (pivot bushings), upper inner, and upper outer ones? Is it necessary to remove the spring, control arms, and shafts to replace the bushings on those 3 places?
