While the arm is out check the condition of the ball joints and replace if needed. After assembly have the front wheel alignment checked.
to remove lower control arm bushings you need to remove control arm from vechicle have control arm bushings pressed out.you need to remove disconnect torsion bar,remove shock absorber,disconnect stabilizer bar link, remove axle half shaft, remove the lower ball joint, remove control arm mounting bolts, then remove lower control arm.
Typically these are replaced with a complete lower control arm. What happens is the ball joint is reseeding the lower control arm and rusts. When the old ones pressed out it distorts the opening in the lower control arm. When the new one is pressed in they never fit tight.
Anew lower control arm is very easy to replace.
1. Jack up the vehicle on the sub frame or pinch weld.
2. Remove the pinch bolt that holds the ball joint to the knuckle.
3. Separate the ball joint from the knuckle.
4. Remove the two bolts that secure the horizontal bushing to the sub frame.
5. Remove the single bolt that secures the vertical bushing from the subframe.
6. Remove the lower control arm.
