Control Arms
1. Lift the vehicle and secure it with jack stands.
2. Remove the wheel to access the control arm.
3. Unbolt the control arm from the chassis and the steering knuckle.
4. Install the new control arm and torque the bolts to manufacturer specifications.
Ball Joints
1. Remove the wheel and access the ball joint.
2. Use a ball joint separator to disconnect the ball joint from the control arm.
3. Install the new ball joint, ensuring it is correctly seated, and torque the retaining bolt according to specifications.
Shock Absorbers
1. Remove the wheel to access the shock absorber.
2. Unbolt the top and bottom mounts of the shock absorber.
3. Replace with a new shock absorber and torque the bolts to the specified values.
Bushings
1. Remove the suspension component associated with the worn bushing.
2. Use a bushing press or a suitable tool to remove the old bushing.
3. Install the new bushing and reassemble the suspension component, ensuring proper alignment.
