1972 Firebird Trans Am Control Arms Upgrades
|
A ball-joint separator is used between the ball joint and steering knuckle. Remember, the front coil spring is under tension and it places great pressure on the lower control arm, which pulls the upper control arm downward. We previously mentioned backing the ball-joint nuts off a few threads. This allows the ball joint and steering knuckle to break free while preventing the control arms from popping apart.
