Tools You'll Likely Need:
* Jack and jack stands: Essential for safely lifting the vehicle.
* Wheel chocks: To prevent the vehicle from rolling.
* Lug wrench: To remove the wheels.
* Socket set and wrenches: Various sizes will be needed.
* Ball joint separator: To separate the ball joint from the steering knuckle. A pickle fork is less ideal and can damage components.
* Control arm bushing removal tool: This is crucial. You can't just hammer the old bushings out; you'll likely damage the control arm. A hydraulic press is best, but specialized socket and hammer/punch sets exist for this.
* Control arm bushing installation tool: Again, this prevents damage. A press is ideal.
* Torque wrench: Absolutely necessary to tighten bolts to the correct specification.
* Penetrating oil (PB Blaster, etc.): Makes removing rusted bolts much easier.
* Safety glasses and gloves: Always protect yourself.
* New lower control arm bushings: Make sure you get the correct ones for your vehicle.
General Steps (Consult your repair manual for specifics):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks.
2. Lift and Support: Safely lift the vehicle using the jack and secure it on jack stands.
3. Remove Wheel: Remove the wheel on the side you're working on.
4. Disconnect Components:
* Brake Caliper: Usually needs to be unbolted and carefully secured out of the way.
* ABS Sensor (if equipped): Carefully disconnect the sensor wire.
* Sway Bar Link: Disconnect the sway bar link from the control arm.
* Ball Joint: Separate the ball joint from the steering knuckle using the ball joint separator.
5. Remove Control Arm: Unbolt the control arm from the frame and the strut.
6. Remove Bushings: Use the bushing removal tool to carefully press out the old bushings from the control arm. This is where a press is highly recommended to avoid damage.
7. Install New Bushings: Use the bushing installation tool to press the new bushings into the control arm. Again, a press is crucial for proper installation and prevents damage.
8. Reassemble: Carefully reverse the disassembly steps, ensuring all bolts are tightened to the correct torque specifications using your torque wrench.
9. Lower Vehicle: Slowly lower the vehicle.
10. Test: Test drive the vehicle carefully, paying attention to any unusual noises or handling issues.
Important Considerations:
* Rust: On a 1994 vehicle, rust is a significant factor. Penetrating oil will be your best friend. If bolts are severely rusted, you may need to cut them off.
* Press: Investing in (or renting) a press for this job is highly recommended. Improperly removing or installing the bushings without a press can easily damage the control arm, rendering it unusable.
* Repair Manual: A Haynes or Chilton repair manual for your specific year and model Chevy Corsica is invaluable. It will provide detailed diagrams, torque specifications, and step-by-step instructions.
This is a general overview. Attempting this repair without the proper tools, knowledge, and a repair manual is strongly discouraged. If you're not comfortable performing this repair yourself, take it to a qualified mechanic. Improperly installed control arm bushings can severely compromise your vehicle's safety.
